How to Identify a Yellow Jacket

To the untrained eye, a honey bee and a yellow jacket might be the same. While they look similar, their behavior can be very different, with yellow jackets being more aggressive. There are several things to look for to spot a yellow jacket. 

The first thing to keep in mind is that a yellow jacket is less furry than a honey bee and a bumblebee. The fur on a bee helps it pollinate plants. Yellowjackets rely on hunting insects and even seeking out human food instead of feeding from plants.  

The predatory nature of yellow jackets also leads them to travel in larger groups than other types of stinging insects. If you see a swarm, you are much more likely to be looking at a yellow jacket. You are more likely to see them swarm in the summer season when their preferred insect meals become less plentiful.  

The final and most obvious way to tell is by the black and yellow bodies that motivated the name. It’s true that bees also have striping, but it is more visible on a yellow jacket due to having less fur. You can notice the striping more when looking at the head of the insect. 

Yellowjackets don’t exclusively nest underground but are the most likely to do so. They are most likely to occupy a hole dug by a rodent. If you see many insects flying out of a hole in the summer, you are likely observing a yellow jacket nest.

Yellow Jacket Nests

The unfortunate thing about yellow jackets is that they can pretty much be found anywhere humans are located. This is because they prefer eating many of the same foods that we do. 

Yellow Jackets fly in a straight line, known as a beeline, useful if you try to locate a potential nest location. Look for an area in your yard that is hit directly by the sun, and see if you can notice any insects flying by repeatedly. If you see this, you are likely to be close to a hive.

It is a common misconception that bees and yellow jackets only create hives above ground. This is, unfortunately, not the case. Check rodent holes for nests, and if they are empty, make sure to fill these holes. Be careful and watch your step in case there are other nests nearby. 

You are most likely to notice a yellow jacket nest in late summer and early fall. The rest of the year, the low overnight temperatures are still too low for active bugs.

How to Get Rid of Yellow Jackets Safely

If you feel like you have a Yellow Jacket nest nearby, locate and mark the yellow jacket nests in broad daylight.

It is not recommended for you to try to get rid of Yellow Jackets yourself. Yellow Jackets are highly aggressive, and even seasoned technicians get stung when trying to treat this pest.

If a Yellow Jacket gets squashed, it releases a pheromone that attracts and incites others of its species. Because of this, people often find themselves getting stung multiple times.

For these reasons, it’s recommended you get a professional to get rid of the nest. Then, you can take preventative measures to deter them from coming back.

How to Prevent Yellow Jackets

When gathering outside, there are ways to prevent those pesky yellow jackets from joining you in the first place. Inspect your yard frequently to stay on top of everything. 

If you have pets or problems with other kinds of pests, you may have a yard full of several holes. Work on filling the holes with dirt to prevent yellow jackets from creating underground nesting hives.

Scraps of cardboard and old wood should be discarded or stored securely. Yellowjackets will frequently build nests out of this kind of material. 

Outside trash containers should be regularly cleaned and sprayed with insecticides before filling the bin. Double-check that the lids fit tightly, so there is no room for the bugs to sneak in. Don’t carelessly dispose of food, be sure to put food in air-tight bags first. Keeping the outside of the bins clean will also help prevent them from looking around this area for a food source. 

If you have a garden or fruit trees in your yard, keep an eye for falling produce. Rotten fruit lying around is a big attractor for yellow jackets, and clearing them out of the way will go a long way.

How to Successfully Get Rid of and Prevent Japanese Beetle Grubs

A portrait Japanese Beetle grub

Japanese Beetle: two words that strike fear into the heart of every lawn-lover and gardener in the United States. 

Japanese Beetle grubs have become one of the biggest problems Minnesotans face each summer. Instead of living in fear of them, you can get to work by trying to control their massive population.  

Environmental Pest Management is here to help you successfully reduce Japanese Beetle Grub populations. They utilize integrated preventive measures along every stage of the beetle’s life cycle. 

When the bugs get to be too much, it’s time to call in the professionals. If you find yourself infested with pests like Japanese beetles, contact Environmental Pest Management. Your free consultation awaits!

Where to Begin? 

japanese beetle portrait

Treating your yard for beetle infestations can be a bit tricky. Like the infamous chicken and egg question, it’s hard to pinpoint where to start. Let’s begin! 


First, be aware of what creature you are up against. The predator that strips plants to the bone and leaves lawns aghast is a creature no bigger than your fingernail. 

The beetle’s shells have a shimmery-green head and rust-colored wings. Deceptively mundane looking, they can be highly destructive. You can see evidence of its presence from early Spring to late Fall. 

Life Cycle

Once identified, it’s helpful to know the Japanese beetle’s entire life cycle from start to finish. 

During the summer mating season, female Japanese beetles can lay eggs. They can lay up to 60 at a time into the soil. This process can happen anywhere from July-September when adult beetles emerge. 

After the eggs hatch, they become grubs. The grubs quickly grow, and white grubs feed on the root systems of lawns and gardens, creating turf damage. Homeowners will commonly see spotty dead spots and patches on lawns

Once grubs have formed and begun their harmful eating, they essentially go through a two-staged process before emerging into adults. The first grub stage is in the Fall when they are new grubs. 

When temperatures begin to drop, the grubs will then burrow deep underground and lay dormant through the winter months. 

The second grub stage begins after the ground thaws. Destruction begins when these slightly more mature grubs viciously feed on root systems in lawns once again.  

After this, the mature grub then begins its metamorphosis into the pupa. Quickly after that, the adult beetle emerges, wreaking havoc on just about every edible plant around. Mating happens, and the process begins all over again. 

Countless plants are susceptible to beetle damage. Gardeners will notice the almost immediate destruction of roses, raspberries, apple trees, beans, and other plants; all brought about by adult beetles. 

The entire life cycle process from start to finish goes largely unnoticed until it’s too late. 

Don’t be discouraged! With Environmental Pest Management here to help, there is still time to disrupt and kill the pests during any stage of their life cycle. 

Japanese Beetle Reduction Process

Even though it takes an entire year or more, the whole life cycle of the Japanese beetle from start to finish is quite simple. However, the means to eradicate them can get a bit tricky. 

Timing is everything. 

Once again, the chicken/egg problem emerges. Thankfully, prevention can start at virtually any stage of its life cycle. As long as it is continued and maintained, beetle population reduction is possible. 

For this example, we will go through the stages starting at the second grub stage when ground thaw occurs in the Spring. 

Spring Grub Stage 

Grub control products for lawn care are found at many home and garden stores. Most of these are chemical-based except for Milky Spore and Neem oils. 

Milky Spore is a natural product that can provide benefits. Even though the product claims to provide lawn assistance, unfortunately, no science currently backs its success. 

Adult Stage

A shiny Japanese Beetle in the adult stage

The next stage to attempt population reduction is the adult stage. This happens in early to mid-July when adults emerge from the ground. Their destructive presence is unmistakable. Gardeners across the US want them as far away from plants as possible. 

Using Japanese beetle traps is an easy and effective option. These contain pheromones which produce an attractive scent the beetle follows right into the well-designed trap. 

It’s best to place the traps in multiple locations around your yard. Traps can fill quickly, so you will want to make sure you have backups as well. 

There are also protective products you can put on your plants to kill or deter the beetles. Conventional and organic options are available at most stores. However, if you have the time, the absolute best option is to hand-pick them off into a bucket of soapy water. 

Breeding and Egg-Laying Stage

Once the egg stage begins, control measures get slightly more advanced. Popular insecticides work well for turf, but they will need re-application after any rainfall. This can get time-consuming for homeowners trying to keep up with endless to-do lists. 

Fall Grub Stage 

Finally, in our example, we reach the fall primary grub stage. Treatment is the same as spring mature grub control. You can apply more granular grub control products from late August into early November or until the ground freezes. 

Prevention is Possible!

Though it can be challenging, controlling the Japanese beetle population is possible. It takes proper timing, dedication, and persistence. Prevention is always best when it comes to any pest type. 

Knowing your enemy and the ways to combat them are great tools to have in your arsenal. Sometimes even the best defense is no match for the plethora of Japanese beetles. 

When the bugs get to be too much, it’s time to call in the professionals! If you are struggling with your Japanese beetle population, contact the experts at Environmental Pest Management. 

Minnesotans only get a few months to relish, don’t waste yours battling a never-ending enemy. Don’t let Japanese beetles ruin any more of your yard or precious ornamentals.

Common Pests Your Crawl Space Attracts

No crawl space is fully immune to bugs and rodents. However, if you stay up to date with regular inspections and treatment from Environmental Pest Management, your chances improve significantly. 

Certain types of vermin are common to crawl spaces in Minnesota. You may encounter the following:

  • Bats
  • Chipmunks 
  • Mice
  • Moles
  • Rats
  • Squirrels
  • Voles

In addition to mammals, insects are notorious for clustering in dark, damp spaces. Common insects found in your crawl space include:

  • Bees and Wasps
  • Beetles
  • Carpenter Ants
  • Cockroaches
  • Earwigs
  • Silverfish
  • Termites

Let’s look at some effective prevention measures you can take to ward off any unwelcome guests. 

Tip #1: Keep Pests Out Of Your Crawl Space By Deep Cleaning and Removing Pest Attractors

A person using a spray bottle to deep clean. Regular cleaning is one way to help keep pests out of crawl spaces.

Crawl spaces are great for storage. However, make sure it contains absolutely no food of any kind, even pet food. 

Pests live and breed near food, including sealed food. Foods attract pests, so make sure your space is devoid of any and all. 

If yours does happen to contain food, make sure to remove it promptly. Then once cleared, give your crawl space a thorough deep cleaning to eliminate any crumbs or remnants. 

Cleaning your crawl space helps fend away pest activity. 

Tip #2: Remove External Debris and Foliage

The bushes and shrubs surrounding your home are natural habitats for all kinds of critters. Making sure your home’s exterior is clear will help prevent infestation. 

Many invasive bugs are attracted to certain types of foliage. For instance, the boxelder bug is known for being attracted to the boxelder tree, from which its name originates. 

Other pests and rodents are attracted to fruit trees and sweet perennials like hostas and roses. Stinkbugs and chipmunks love anything sweet and are notorious for hiding indoors when cold weather hits. 

Foliage from nearby trees can push up against the house, creating damp hiding places suitable for pests. Keep pests out of your crawl space by clearing all loose debris away from your foundation walls. 

Tip #3: Seal Cracks and Openings

Once the debris has been cleared away, it will be easier to spot any cracks or openings in your foundation. 

Cracks are an open invitation for pests to enter your home. 

Seal these open cracks with caulking, foam insulation, wood, or cement blocks and replace any broken boards. 

Tip #4: Shine a Light

Most crawl space bugs and rodents will flee at the first sign of light. 

You can’t stay down in your basement or crawl space with a flashlight 24/7. But you can have simple LED lighting installed. 

Low-cost and energy-efficient LED bulbs will help keep pests away. And if your space has any appliance parts or piping, it will be easier to service them with proper lighting. 

Tip #5: Set Traps

Setting traps is effective, cost-efficient, and they do the job of keeping pests out of your crawl space. Traps should be placed both inside and outside the home. 

Not all traps are created equal. Traps purchased through a local retailer work for the short term, but the poison wears out over time. 

Another “trap” is having a pet who hunts. Some cats are great hunters for vermin like mice and rats, and dogs will occasionally eat certain bugs. 

Keep pests out of your crawl space by letting your pets inspect the area. Just make sure you don’t have any poison traps around when they’re running loose.

Tip #6: Install Proper Ventilation

Crawl space rodents and insects thrive in humid environments. To lower humidity and moisture levels, install a dehumidifier. 

While dehumidifiers are a quick fix, a ventilation system is best at keeping mold, mildew, and wood rot at bay. Vents can both open and close, which adapts well to Minnesota’s constantly changing weather. 

Most new homes are built with crawl space ventilation systems. However, if your home is older, you will want to remove and replace moisture-rotted beams before installation. 

Dirt and concrete walls and flooring will help further prevent moisture from spreading. 

Each state’s HVAC IRC code varies, but most ventilators are required to cover 150 square feet of crawl space. Be sure to check with your city’s code to make sure you have enough. 

Tip #7: Crawl Space Encapsulation

The most effective way to control moisture levels, create a vapor barrier, and seal off any cracks is plastic encapsulation. 

A 20-millimeter thick encapsulation will create a plastic vapor barrier in your crawl space. It will cover the floor, walls, and ceilings, so pests can’t enter your crawl space. 

Regular Inspections Are Best

Keep Those Bugs At Bay! How Does Bug Spray Work?

A parent spraying their child wit bug spray while doing outdoor activities.

Bugs are part of summer, and so is bug spray. But how does bug spray work, and is it safe? Today you will learn all you need to know about everything bug spray. 

Summer is the best time of the year. There’s nothing quite like getting together with your friends and family, basking in the sun, and enjoying your backyard. 

There are endless opportunities for day trips, including going to the lake or a park. Unfortunately, a day outside often ends with the family covered in bug bites, and that itching can last for weeks. 

Environmental Pest Management provides bug control services in the Metro Twin Cities area and surrounding suburbs. We use safe products to protect the planet and your family. 

When bug spray isn’t enough for your yard, give us a call! 

What Is Bug Spray Made Of?

Bug spray is excellent for making sure you’re not covered in itchy dots at the end of the day. 

Over the years, you’ve probably noticed the weird smell of many sprays, which has to do with the various ingredients. The main ingredient you will find in most bug sprays is DEET (also known as N, N-diethyl-meta-toluamide.) 

DEET was first produced in 1944 as a pesticide in farm crops. DEET has been found to be slightly poisonous to some freshwater fish, but it is EPA-approved.

A study was released in 2014 by the United States Environmental Protection Agency (EPA.) It stated that “The Agency has not identified any risks of concern to human health.”

Many common sprays contain lemon eucalyptus oil. It serves as both an insect repellent and a remedy for killing certain types of fungus. 

Researchers say that the oil is as effective and long-lasting as products containing DEET and is a better natural alternative. 

Another ingredient that you are likely familiar with is citronella oil, which you can also find in candle form. 

Citronella is derived from an Asian grass plant known as the Cymbopogon genus. The plant produces a citrus-like aroma.

It is less protective than DEET, often only lasting for around 3 hours before you need to reapply.

Bug repellents work by irritating insects, so they don’t land on you. Natural alternatives also encourage bugs to leave the area.

How Does Bug Spray Work?

You apply bug spray on a regular basis, but do you know exactly how it works?

The average bug spray isn’t designed to kill bugs but instead fights them off. 

Bug spray works by disguising the scent of your body from bugs. 

Bugs, like mosquitos and ticks, are attracted to the carbon dioxide that the human body produces. 

Carbon dioxide is released from the body through your sweat glands, pores, and even your breath. Pests associate this smell with a food source. 

Pests find the smell of bug sprays repulsive, which helps to keep them away. Try to stay away from lavender and basil as they are highly attracted to these scents.

While bug spray is a repellent, insecticides are used to kill bugs such as ants, cockroaches, and hornets. There are so many different kinds of insecticides because the goal of these sprays is to administer a quick death. 

The chemicals do this by causing paralysis and attacking their central nervous systems.

There is a flower called Pyrethrins, which produces natural insecticides. The flowers look similar to daisies and have been used for hundreds of years to kill bugs and head lice. 

Pyrethroids are synthetic chemicals in Insecticides that mimic the effects of the flower. This chemical is most commonly used in wasp and hornet sprays. 

Insecticides are best used late at night. A hive tends to be less lively at night, and they are less likely to attack you when you spray. 

While bug spray works by getting insects out of the area, insecticides work by killing the pests.

Are Bug Sprays Safe?

Someone spraying a can of blue bug spray into the air.

DEET, the most common active ingredient found in household bug sprays, is a pretty controversial topic. Although the EPA registered DEET without any expected health concerns, DEET is an irritant that can often cause rashes. 

The American Academy of Pediatrics (AAP) warns parents not to use DEET on children under two months of age. But other than that, there are no age restrictions. 

Surprisingly, the only repellent with an active age restriction is the oil of the lemon eucalyptus plant. They state that it should not be used for children under three years old. 

Natural Alternatives

Two class amber-colored bottles filled with eucalyptus oil.

As mentioned above, lemon eucalyptus oil is a widely used natural alternative to most repellent sprays. There are also alternatives to harsh chemicals that kill bugs on the spot, though they may not be as effective. 

Soap sprays have been found useful for killing pests like mites, psyllids (plant lice), and whiteflies. The sprays work by covering the bugs in soap which cuts off their oxygen supply, essentially suffocating them. 

You can make your own soap spray simply by putting some mild liquid soap in a spray bottle. While less effective than a commercial spray, it is completely non-toxic. 

Diatomaceous Earth is a powder you can find in most gardening aisles, which acts as miniature shards of glass. The powder works best against bugs that crawl, like ants, maggots, spiders, and worms. 

Apply it around vulnerable plants, and pests will be torn up when they crawl through it. Diatomaceous Earth only works when dry, so if it storms, you must sprinkle more. 

There are also various species of plants that can be put in your yard that act as a natural repellent. To find out more information, visit our article on 7 Plants that Help to Keep Mosquitos Away.

Do LED Lights Attract Bugs?

An LED bug zapper
An LED bug zapper

LED lighting has proven itself to be an energy-saving option to traditional incandescent or fluorescent lightbulb. When it comes to being outdoors, though, do LED lights attract bugs or deter them?

Insects are attracted to lights. We see examples of this by looking up at street lamps at night and seeing the swarms around them. 

Their attraction to light is based on an instinctual draw that helps them navigate the earth. 

At Environmental Pest Management, we understand the nature of the pests that we treat. We treat pest problems wholly and humanely in the Twin Cities greater area of Minnesota. 

For integrated pest management, we have a goal to know the life cycles of insects and their behavioral patterns. Those patterns include their attraction and relationship to lights.

Do LED Lights Attract Bugs? Here’s How Lights Measure Up.

A diagram of visible light and wavelengths

One way that light can be measured is in wavelengths, which are measured in nanometers. 

Warmer colors such as red, orange, and yellow measure longer wavelengths of light and are less visible to insects. Cooler colors, on the other hand, are measured in shorter wavelengths. 

The range from red-colored to UV light measures anywhere from 400-800 nanometers. Cooler tones will register 300-650 nanometers. 

Ultraviolet or UV light lies with the cooler colors and registers at 350 nanometers. That reading makes it very attractive to insects. 

Flying insects primarily use the light that they see to navigate. Much like humans, the light they see is only a fraction of the entire light spectrum. 

400 – 800 Nanometers

  • What humans see 
  • Ranges from the color violet to red 
  • It does not include UV light

350 Nanometers

  • Ultraviolet light

300 – 650 Nanometers

  • What insects perceive and are attracted to 
  • Includes UV light 
  • Insects prefer light that falls between 300 – 420 Nanometers. 

Insects can see UV light and are attracted to it, so many bug lights use it. 

 The three primary colors that bugs see are UV, green, and blue: the cooler tones on the light spectrum. Insects are less able to register warmer colors like orange, red and yellow. 

Staying away from lights with cooler tones can keep flying insects at bay in your outside spaces. Cooler-colored lights are often used in outdoor settings because they appear to be brighter. 

These were also the only lights available to customers for decades.  Bugs swarming around them at night was quite normal. 

An LED bulb that gives out a warmer tone will be just as bright without attracting annoying flying insects. LED lights with higher wavelengths do not attract bugs because the bugs can’t see them.

Going Toward the Light 

Do LED Lights Attract Bugs? Someone swapping an incandescent light bulb for an LED bulb because they do not attract bugs.

Traditional incandescent light bulbs are cooler in tone and put out a lot of heat. These light sources are typically used outside and attract flying insects. 

Incandescent and halogen bulbs are especially attractive to insects because they give off the most heat. 

These bulbs give out 90% of their energy in the form of heat. This is really important to the insects who navigate with heat receptors.

Insects of the blood-sucking persuasion are attracted to the change in temperature from one thing to another. So when a mosquito, for example, senses a higher temperature, they will go to it. 

The bloodsuckers interpret the change in temperature as a sign of a food source.

This is one of the reasons that insects are attracted to traditional lighting. The light insects are most attracted to is one that puts off lots of heat.

So, do LED lights attract bugs? 

LED bulbs are built to be more efficient and give off much less heat. Insects feel less of a change in temperature, so they aren’t drawn to these lights. 

This means you are not only running a more efficient household: you are avoiding bugs. You, my friend, are officially multi-tasking. 

Bug Zappers and Color Lights

A blue bug zapper surrounded by dead bugs.

Bug Zappers attract insects by using UV light to attract the bug. When the insect is in range, the device sends out a jolt that electrocutes it.

The bug zappers that come to mind are ones that glow purple with UV light and have bugs around them. 

They are often large and are accompanied by a loud buzzing and zapping sound.

Today there are  LED options for bug zappers that draw insects into the kill zone using UV light. The rest of the bulb, however, is an LED light that will not have a cloud of bugs around it. 

LED lights do not attract bugs the way incandescent lights do. But they do help make bug lights more efficient.

The LED options are also quieter than traditional bug zappers. 

If bug zappers aren’t an option for you, color lighting is an alternative. As we’ve covered, bugs are primarily attracted to “cooler” colored lights. 

Use a bulb that throws out a warm color light to draw fewer flying pests.

LED Lights Do Not Attract Bugs, So Keep The Light On.

Are There Any Plants That Keep Mosquitos Away?

A bright flower garden in someone's backyard.

There are a variety of plants that may help deter mosquitoes. They also smell amazing and are fabulous additions to your Minnesota landscape.

Plants alone are unlikely to deter large amounts of mosquitos. Most natural repellents are made from the extract of the plant, not the plant itself. 

So unless you’re crushing your plants, you may be happier combining this strategy with other methods.

Start by clearing away any standing water in birdbaths or other containers. Mosquitoes love to lay their eggs in stagnant water. Then, add some of these plants to your backyard design.

Plants That Keep Mosquitos Away

1. Citronella Grass 

A citronella plant planted in the ground. Citronella is a plant that help keep mosquitos away.

Citronella may be the best-known plant for keeping mosquitos away.

Also commonly known as lemongrass for its scent, citronella grass is a common ingredient in most bug repellents. It’s also common in outdoor candles and torches meant for mosquito control. 

This beautiful lemon-scented plant is hearty and can grow to be quite large. The fragrant plant thrives in full sun and warm weather. 

You can use a potted citronella plant as a natural mosquito repellent in your home. Be sure to protect it from cooler temperatures. 

2. Marigolds

Bright orange flowers planted in a garden known as Marigolds.

Who doesn’t love a multi-tasker? Marigolds are an easy to grow annual plant that not only keeps mosquitos away but also protects against: 

  • Aphids
  • Tomato HornWorms
  • Squash Beetles

All of those pests can be harmful, especially to vegetable and flower-based gardens. Marigolds are also ideal for making a border when landscaping. 

3. Mint

A closeup of mint plant leaves.

Mint is a welcome addition to any yard or garden based on its scent alone. Not only does this plant keep mosquitos away, but it also smells lovely.

The more intense the smell of mint in the air, the better it is working

There are other reasons to plant mint in your yard. Different types of mint not only repel mosquitoes and other pesky insects, but it’s excellent for cooking and making refreshing drinks. 

Peppermint is excellent for nausea and other around-the-house uses as well, like cleaning and aromatherapy. 

4. Bee Balm 

Purple flowers known as Bee Balm.

Also known as Monarda and Horsemint, these are some colorful flowers. They come in red, pink, lavender, white, and purple. 

These gorgeous colors make them a helpful addition to any landscaping project. The chemicals that fight mosquitoes can be released by crushing the leaves to release the oils. 

The oils released have a pleasant fragrance. It is also attractive to both bees and hummingbirds, which are always welcome for pollination.  

5. Lavender

Purple Lavender flowers. Lavender is a plant to keep mosquitos away.

Lavender is widely known for its relaxing fragrance and medicinal properties. A lesser-known property is pest management. 

The oils and chemicals of this power plant will block the sense of smell for mosquitos. It can also keep rabbits and other pests out of your yard. 

Lavender is drought-resistant and is very low-maintenance, needing only good sunlight and drainage. 

6. Rosemary

Commonly used in cooking, rosemary is also excellent for deterring mosquitos! 

If used in landscaping, rosemary can protect lawns and gardens from carrot flies and cabbage moths as well. 

It is best to grow rosemary in a pot, as it seems to thrive when placed in them. Potting this plant also makes it ideal for use in the winter for seasoning. 

7. Sage 

A sage plant.

Sage has been used for centuries for several purposes ranging from spiritual reasons to ceremony to cooking. 

The smoke from sage plants can be used to stave off mosquitos. This is a great trick for those with a firepit or a campfire. 

Some insect-repelling plants that deserve an honorable mention include lemon balm, floss flowers, and scented geraniums. Adding any of these plants to your landscape will help keep mosquitoes away. 

Extracts and Natural Oils From Plants That Keep Mosquitos Away

Getting the most out of your home is important. The plants being used in landscaping and decor should be no different. 

Some plants keep mosquitoes away better after a bit of processing. The oils and extracts that are found in these plants should serve in more than decor and repelling pests. 


Lavender oil and extracts have been used in aromatherapy, spa treatment, and, yes, mosquito repellant. Not only does it smell good and get rid of pesky pests, but it helps you to relax as well. 

Bee Balm 

The extracts of the bee balm plant have several uses. Medically, the extract can be used for scrapes, stings, and stress relief. 

To release the oils and extracts, simply crush its leaves. 


For the most part, citronella oil is burned to protect humans from mosquitos. It can be found in anything from candles to spray bug sprays.

How to Identify June Bugs

A large June Bug on a green leaf.

There are hundreds of June bugs species, but in Minnesota, there are roughly 20 bugs with this name. June Bugs in our area are about an inch long and have an oval-shaped body.

These bulbous bugs have six hairy-looking legs and a pair of black antennae. They are dark brown, although some appear almost black or maroon. 

The June bug’s back and body is a hard, smooth shell with a uniform color and no markings. The underside is hairy. 

When they walk, they move in a bumbling way, almost as though their legs are too short for their bodies. When they fly, they always look like they’re about to crash.

They certainly are goofy, graceless bugs.

June Bugs are unique insects with two sets of wings. That hard shell covering the backside is a set of wings. There’s a second pair underneath the first.

The top set of wings serves to protect the bug but sticks out straight to be out of the way in flight. The top wings sticking out make this bug aerodynamically awkward.  

What Is A June Bug’s Life Cycle?

June Bug Larvae on potting soil

Adult June Bugs show up in or around (you guessed it) the beginning of summer. But where do they originate?

The bug begins life as an egg. The little white egg takes about three weeks to hatch.

The June Bug larva makes its way into your soil. It has a huge appetite, and it will molt twice before moving to the next stage of life. 

The bug will continue in the larval stage, eating roots and growing for one to three years. 

When the larva has grown and matured enough, it enters the pupal stage.

The pupa starts dark brown, gradually taking on an iridescent sheen. The pupa remains underground and doesn’t move at all during this stage.

The pupal stage lasts about three weeks. When this stage ends, the adult bug finds its way out of the ground and flies off to find a meal.

What Draws June Bugs To Your Home Or Yard?

June Bugs are attracted to moist soil and organic material. If you leave grass clippings left in your yard, June Bugs will be happy to dine there.

Damp soil is an ideal place for June beetles to lay their eggs. When the eggs hatch, the June Bug grubs will burrow into your lawn.

June Bugs are drawn to any light source. If you have exterior lights on in early summer, you are likely hosting a nightly June Bug party. It may be the reason you’re researching how to get rid of June Bugs!

What Harm Do June Bugs Cause?

This flying, bumbling beetle is not a danger to people, and they do not want to bite or eat you. But June Bugs are interested in your plants.

June Bugs eat a wide variety of plant leaves, making Swiss cheese out of your lawn and garden. But that’s just the start.

The bugs lay eggs in your soil, turning your yard into a June Bug nursery. When the eggs hatch, the grubs feast on the roots of your plants.

A grub infestation can cause patches of dead grass to show up on your lawn. Brown patches in your yard are a sign of grubs munching on your roots.

Bugs in your lawn can also attract other animals notorious for being pests. Skunks and raccoons will dig small holes digging up grubs for dinner. 

How To Get Rid Of June Bugs

The first step to getting rid of June bugs is to focus on the adults. 

If you aren’t squeamish, grab a pair of gardening gloves and pick the bugs off your plants by hand. Place them into a jug of soapy water to drown them.

If you prefer a hands-off approach, try this integrated pest management approach. This DIY insect killer is safe for humans and the environment:

  1. Mince four cloves of garlic. Soak them overnight in a tablespoon of mineral oil.
  2. Drain the oil, then add the garlic to a pint of water.
  3. Add a teaspoon of dish soap to the mix. 
  4. Put two tablespoons of your mix in a pint-sized spray bottle. Fill the remainder with water.

To get rid of June Bugs, spray the ones you see, as well as the plants they’ve been munching. The method also works well on Japanese beetles.

You can also reduce your June Bug count by installing a bug zapper. These bugs are notorious for heedlessly heading into lights. They fly straight into a crispy end with this contraption.

Once you’ve gotten control of the adults, you’ll need to address the grubs. 

June Bugs like to lay eggs in short grass, so don’t mow your lawn too low. You can set the mower to at least three inches to keep it at an ideal height. 

Deal with grubs naturally by introducing nematodes to the soil. You can purchase these microscopic worms online or at a garden center. Apply them with a spray bottle. 

A similar method is to apply a bacteria called Bacillus Thuringiensis, or BT. Apply in a spray or powder form to safely eliminate grubs.

If you need a more robust solution, try an insecticide that contains neem oil. This compound is toxic for many larvae but will not harm most beneficial bugs

Pests That Affect Your Pets: Fleas vs. Ticks

Outlines of a flea vs. tick

Have you ever woken up in the middle of the night to your animal incessantly scratching? Your dog could be scratching because of a common pet pest. The scratching can be from a pest, but is it a flea vs. a tick bothering your pet?

Fleas and ticks are tiny parasitic bugs that can cause people and animals irritation and transmit diseases. Though both fleas and ticks are tiny parasites, irritate, and transmit disease, they have more differences than you would think.  

If your home is teeming with tiny parasites, contact Environmental Pest Management for a successful pest control service.

Pests that Affect Your Pets: Fleas vs. Ticks

Three small dogs itching for fleas vs. ticks.

The most noticeable difference between fleas and ticks is that fleas like to invade. Fleas will infest your pets and invade the inside of your home. 

In contrast, ticks prefer to stay outdoors and will latch on to your pets if a suitable host wanders by. Both of these bugs have differences in characteristics, habitats, behaviors, bites, and how they spread disease.

Let’s dive into the differences!

Fleas are a dark reddish-brown color. They are easy to mistake as dirt in your pet’s coat.

They have tiny backward-pointing hairs that extend from their exoskeleton. They use their extended mouthparts to feed on their host’s blood. 

Although they may appear to be flying, this is not the case. They do not have wings.

Fleas use their strong hind legs to leap up to 13 inches or 200 times their body length.


An enlarged photo of a tick on a white background

Depending on the species, ticks are usually larger than fleas. There are more than 850 species of ticks, and 90 of them can be found within the United States. 

Ticks can be a black, brown, reddish-brown, grayish-white, or yellowish color. They are more of a teardrop or oval-shaped bug with a large abdomen used for feeding. 

Adult ticks will have eight legs, while tick larvae will only have six. Ticks have three life stages: Larval, nymph, and adult- all of which are capable of biting. They are a close cousin to spiders. 


A shaded area with tall grass is the perfect habitat for fleas and ticks

Fleas prefer to live in shaded areas with lots of tall grass. Since ticks cannot fly or jump, they prefer to live closer to their hosts. 

They will live in wooded or grassy areas close to homes or near rat burrows or bird nests.

What weather can they tolerate? Most of the time, we think of “flea and tick season” as the warmer months. 

While it’s true for fleas, they thrive in warmer environments. On the other hand, while yes, ticks thrive in warmer weather, they can survive the colder months. Some even hide underneath the snow.    


A tick biting human skin.

Fleas usually avoid biting humans unless there are no other suitable hosts nearby. Fleas will find one host, usually a dog or cat, and live there until they die.

On the other hand, ticks are not as particular. 

Ticks will attach themselves to multiple hosts and feast for a few days until they are engorged with blood, then move on to the next. Ticks will feed on pets, deer, opossums, rabbits, rodents, and even humans. 

 Fleas use their powerful hind legs to jump to and from their hosts.

Since ticks can’t fly or jump, many species of ticks wait for their hosts in a position called “questing.” When questing, the tick will hold onto a leaf or grass with its hind legs with its front legs outstretched.

Then once a host wanders by that area, they will quickly climb aboard and search for a place to latch.

Fleas vs. Ticks: The Bites

Flea bites on a leg.

When a flea bites its host, they inject their saliva into their skin. This can cause your pet to experience skin irritation, rash, and itchiness. 

When a tick bites, it is usually painless, and the negative symptoms will not appear until the tick has finished feeding. The symptoms of a tick bite can include pain at the site, swelling, rash, headache, sore muscles, or fever.

How They Spread Disease

A doctor removing a tick from a person's hand.


Fleas can spread diseases such as typhus and plague. Fleas become infected when they bite an infected animal such as a rat, opossum, or stray cat. 

When the fleas bite their host, it causes a break in the skin. When the fleas feed, they poop. 

The poop is called “flea dirt.” The flea dirt from the infected flea can get rubbed inside the wounds. 

It is also possible for people to inhale in the infected flea dirt or rub it into their eyes.


Ticks can transmit diseases such as Lyme disease, Rocky Mountain Spotted Fever, and tularemia through feeding. 

Depending on the species of tick and which life stage it’s in, it can take anywhere from 10 minutes to 2 hours to find a feeding spot on its host’s skin. Once the tick has found its feeding spot, it cuts into the surface of the skin and inserts its feeding tube. 

Many species of ticks have a barbed feeding tube that helps keep them in place while feeding. They can also secrete a sticky substance to help keep themselves attached to their meal.

Before ticks bite, they can secrete a small amount of saliva that contains anesthetic qualities. The host will be unaware of the tick’s attachment.

The tick can go unnoticed in a hard-to-reach or out-of-the-way spot. Then the tick will feast on the blood slowly for a couple of days. 

If the host has any bloodborne pathogens, the tick will ingest them with the blood. Tiny amounts of tick saliva can enter the host during the feeding process. 

The infected saliva from the tick can transmit pathogens to the host during the feast. Once finished feeding, the tick drops off to prepare for its next stage of life. 

Any acquired pathogens or diseases can be transmitted at the next feeding. 

Protect Your Pets

Preparing yourself for fleas and ticks is the best way to protect you, your home, and your pets from fleas and ticks. When it comes to fleas and ticks, it is best to use prevention methods. 

Keep your yard mowed and landscaped to help keep them from living in your backyard. Do not leave out any pet food that may attract unwanted animals, such as opossums or raccoons.

Talk to your veterinarian about a flea and tick treatment for your pet. And keep your pet’s bedding or carpets and rug clean to prevent flea infestations. 

If you think you have a tick infestation or live near a wooded area where ticks love to hang out, call Environmental Pest Management for help. We will prevent pet pests from infiltrating your home.

Protect Your Home and Yard From These Stinging Insects

Summertime is a season of sun, vacation, backyard barbecues. Inevitably, it’s also the season of stinging insects. 

How can you best prevent those pesky wasps, hornets, and bees from interrupting your party?

Wasps, hornets, and bees: what’s the difference?

Wasps and hornets can be quite an annoyance at your garden party. Being more aggressive, they are harder to deal with than the friendly bee. 

Wasps and hornets

Wasps appear armor-plated with a sleek, hairless body. The most common wasps in Minnesota are yellow jackets and paper wasps.

Yellowjacket wasps are yellow and black. Their thorax ends with a pointy tip. 

Paper wasps have a segmented body with a thin waist. They have dark coloring with smokey black wings.

Hornets are a wasp, but their bodies are a little rounder than yellow jackets or paper wasps. 

Social hives versus solo-resident nests

When wasps and hornets live communally, you can find their nests in trees, under the eaves of a house, or porches. These stinging insects can also live in individual nests usually found in sand or soil locations.

They raise their young in communal hives. Like honey bees, wasps and hornets have a single queen.

Wasps and hornets generally are not interested in humans unless they are defending their nests. The stinging insects are quite territorial, and if you come within a yard of their nest or hive, these insects may attack you. 

Carnivorous hunters

Wasps are predators and use their stingers offensively and defensively. They sting to stun or kill their prey, and they sting to ward off threats. 

Wasps can sting their target multiple times.

Wasps and hornets are essential in helping control the population of small insects. They also feed on sweet nectars from flowers and fruit trees. 

Honey bees or bumblebees

While these flying insects can also sting, they are generally much less aggressive.

Honey bees are yellow and black flying insects that grow fuzz or fur on their bodies. The presence of hairs on the bee’s body helps you differentiate them from yellow jackets. 

Bumblebees are rounder and plumper than honey bees. They also have black and yellow stripes and fuzz all over their bodies. 

Communal hives

Bee keepers checking on their honey bee hives.

Honey bees live in hives with a single queen, and their nests are often found in trees. Bumblebees live in holes in the ground. 

Helpful and hairy

Bees are helpful pollinators, and much of our fruit, grain, and vegetable production depends on them. Pollen attaches to their hairy bodies and is deposited to other flowers as they fly from bloom to bloom. 

While generally less aggressive, honey bees can only sting once, then die. If possible, do not kill honey or bumblebees, as they are important to our ecosystem and can be considered a beneficial insect

What happens when you get stung?

No question, stinging insects no fun. What is a stinger’s anatomy, and what is the biological response in your body after you get stung?

History of the stinger

A closeup of a wasp or yellow jacket stinger

In prehistoric times, the stinger was not for attacking but instead was how female wasps laid their eggs. This anatomical feature is why only female wasps and hornets have stingers. 

Anatomy of the stinger

Wasp venom is produced and stored in a sac near the stinger. The poison seeps out through valves, which leads to the sheath which holds the stinger.

The smooth stinger is coated in venom. The wasp is always ready to respond to a threat or attack. 

When you are stung by an insect, your body has a few biological reactions—the most common being: pain, redness at the site, and swelling. 

Why does it hurt?

A close up of a bee sting on someone's arm.

Peptides and enzymes in venom will break down cellular membranes in your skin. When neuron cells are affected, the injured cells send a signal to the brain. 

That message translates into the sensation of pain. 

Another element in stinger venom is a chemical that acts like norepinephrine. This chemical slows blood flow, which causes the pain to continue for several minutes.  

Hyaluronidase and MCDP (Mast Cell Degranulating Peptide) are also present in venom. They potentiate the enzymes that break down cell walls in your skin, which is why wasp and bee sting often lead to swelling and redness in the area. 

How to prevent wasp and bee stings

While it can be challenging to avoid stinging insects entirely in the summer, here are some great tips to encourage them to stay away from you and your loved ones.

  • Minimize wearing strong perfumes or scents.
  • Food smells especially attract wasps. When eating outside, clean up food scraps and leftovers quickly.
  • Avoid wearing dark colors and bright floral patterns as they are all attracted to these colors.  
  • Keep outdoor waste cans away from where people may be congregating as wasps are attracted to garbage. 
  • Wear closed-toe shoes if possible when walking on the grass. 

Most importantly, nests found near your home or in areas where people gather must be safely removed. It can be very dangerous to your health if the wasps or bees become angry and aggressive, so don’t try to remove them yourself.

Especially if you have an allergy to bee venom, do not attempt to remove a nest yourself.

Diapause and Pest Control

Dealing with an infestation of insects is a nightmare for many homeowners. It can be a real challenge to clear the pests completely.

It is a good idea to invest in the services of a professional pest control company. Experts who have a strong background in tackling several pest control problems: including diapause.

Insect diapause is a natural process in the lifecycle of an insect. Several external factors can cause it—and understanding these can be key in preventing an infestation.

Here at Environmental Pest Management, we know how to tackle any infestation—including a sound understanding of diapause. Get in touch with the team and see how we can help!

What Is Insect Diapause?

A flesh fly

In the simplest terms, diapause is a period of arrested development or reproduction in insects. The state is usually triggered or terminated by environmental conditions. 

Temperature, availability of food, changes in daylight, or temperature fluctuations are all regulators of diapause. Combinations of these can also set off insect diapause in a wide number of species.

There is an important distinction to be made here; the diapause response is ultimately genetically programmed. The aforementioned environmental factors do not cause it, but they can determine when it starts and ends. 

Quiescence, on the other hand, is a period of slowed development. Unlike diapause, this is triggered by environmental conditions, ending when optimum conditions return.

What Are The Main Environmental Factors?

As we mentioned, a range of environmental factors can play their part in insect diapause. Some of these include:

  • Temperature

Sudden changes in temperature, such as extremely cold or hot periods, can trigger the beginning or end of diapause. Additionally, alternating cycles of temperatures can also influence the process. 

The exact trigger and temperature will depend primarily on the type of insect; each has its unique requirements and cues.

  • Photoperiod

The term ‘photoperiod’ refers to alternating phases of sunlight and darkness throughout the day. Suppose there is an alteration in the phase due to external factors such as seasonal changes. In that case, the process can be triggered with shorter days and less light.

In many ways, the photoperiod is the most important aspect of insect diapause. It is also easy for pest control professionals to manipulate, as they can artificially create light cycles.

  • Food

As some insect species come to the end of their growing season, their food sources’ quality also deteriorates. Once again, this process can trigger diapause in certain species.

What Are The Types of Insect Diapause?

It is important to note that insect diapause comes in two main types: obligatory and facultative. The difference is important as it dictates when and why insects enter the phases of diapause.

Insects with obligatory diapause begin the period of arrested development at a point in their life cycle, which is predetermined. The process occurs despite any external environmental conditions. 

Obligatory diapause generally occurs mainly with univoltine insects—in other words, those who have one generation each year.

On the other hand, insects with facultative diapause will undergo diapause only if it is essential for the creature’s survival. It is the most common type of diapause, found in the majority of insects. 

This type of diapause is more commonly known as overwintering, and it is similar to hibernation in some mammals.

Facultative diapause is associated with bivoltine (insects producing two generations a year) or multivoltine insects (over two generations per year).

It is also worth mentioning reproductive diapause; this is a suspension of reproductive functions in an adult insect. It is commonly found in species such as the monarch butterfly, which goes into reproductive diapause to prepare for the long migration.

Why Can Diapause Be A Problem For Pest Control?

While diapause is a natural phenomenon, it causes serious issues for the management of pests and unwanted insects. 

When diapausing, insects can endure adverse environments such as extreme temperature or moisture. They can also handle food shortages more readily and be able to withstand toxic chemicals and ionizing radiation.

Perhaps most crucial, diapausing insects can delay reproduction. It is integral if you aim to reduce population growth and is a key factor in your pest management regime’s timing.

All of these factors are critical elements of pest control. If they no longer work effectively on the insects, it is hard, if not impossible, to eliminate your pest problem. 

As the insects build up a tolerance to the factors we discussed – temperature, chemicals, etc. —they can resist a pest management program. They may also be able to synchronize their reproduction program to their maximum advantage, making full use of available resources.

What Can Be Done?

A dead bug on its back

It seems that the only way to tackle insect diapause for pest control is to learn to use it to our advantage. The process involves manipulating external factors to prevent the onset of diapause, giving pest control a chance to work by pinpointing the perfect time to use pesticides.

Controlling external factors is hardly a new concept; a recent study experimented with using artificial light to extend the day’s length in preselected plots. 

The test saw a 76% and 70% decrease in the onset of diapause in two insect species. Non-diapausing insects were then unable to survive the harsh winter, allowing control of their numbers.

In some cases, one can carefully manipulate reproduction; this allows pest control experts several options. They may calculate the predicted reproduction time and use it as a window to maximize the treatment’s effectiveness. 

Alternatively, experts may act to eliminate the insect before reproduction can occur—this can bring numbers down to more manageable levels.

Also, no stored-product insect species are currently known to diapause in the egg stage, and only one in the pupal stage. This information can also be useful to pest control experts, giving them a window to act.

There are also potential benefits from waking insects early from diapause or preventing it entirely. If these things can be done, the insects will likely die naturally from winter’s harshness and won’t need to be treated with pesticides.
