Little Brown Bats and Big Brown Bats: How to Know if You Have a Bat Problem

Bat

Bats are Pretty Cool, as Long as They’re Not Living in Your House Rent-Free

Little Brown Bats and Big Brown Bats play a significant role in our ecosystem here in Minnesota. They eat an excessive amount of insects and often serve as pollinators to some species of plants.

Bats also serve as a vital food source for other predators. Because of their roosting patterns in large numbers, they are an easy catch for other mammals, predatory birds, and snakes.

We can surely all agree that bats at a distance, or even flying around in our neighborhoods at night are a nifty example of nature at work in all her glory. However, if those bats are roosting in your home, apartment complex, or business property, “nature” can get a little too close for comfort.

At Environmental Pest Management, our goal is to help nature do its best work outside of the confines of your home, apartment complex, or business. Call us today to send an eviction notice to your pests and make sure they leave you alone.

There are Two Main Bat Species that May Want to Move in and Set up House in your Home

In Minnesota, two bat species commonly show up as pests in our homes or properties: The little brown bat and the big brown bat.,/p>

The Little brown bat:

A tiny creature that weighs just half an ounce, this bat is prolific and well-traveled. These bats are red or brown colored and have a wingspan of 8-11 inches. Little brown bats are found all over the United States, Canada, and Mexico, but with fewer numbers in the south than in the north.

These little guys “shack up” in the hundreds of thousands, and have day and night roosts, as well as summer homes and winter “hibernation” hide-outs. They favor caves, rocks, trees, woodpiles, and buildings to rest, sleep, or raise their young.

Little brown bats eat mainly insects, so you have them to thank in large part for keeping mosquito and other insect populations from running completely rampant in our neighborhoods and on our rural farms and lakeside “playgrounds.”

You will likely notice bats at the height of their daily feeding frenzy just a few hours after dusk. They must eat at least one half of their body weight in insects each day to survive. Surprisingly, bat mothers must eat at least 100 percent of their body weight each day to live and feed their young.

The Big Brown Bat:

This bat has a coppery sheen to their fur and a wingspan of 12-16 inches. It weighs one-half to just over an ounce and has a different facial structure than the little brown bat. The big brown bat is also exceedingly common, living from the Carribean Islands and northern South America to the north of Canada. They are everywhere in the United States.

Big brown bats eat insects, and their favorite food is beetles. Their teeth are well equipped to break the tough exoskeletons of beetles, but they will also eat flying insects as well. Big brown bats may check out your attic or walls and decide your home or building is a perfect place to hibernate or rest.

These bats are the speed demons of the bat world, achieving flights speeds of 40 miles per hour. They can also live long lives (hopefully not as freeloaders in your space) of up to 20 years. They adapt well to a variety of habitats, including deserts, cities, forests, and mountain ranges, to name a few.

Do you have a bat problem?

Bats and Big Brown Bats

Here are some signs of a bat infestation:

  • Droppings around your attic vents
  • Scratching or squeaking sounds in your walls or attic
  • Seeing bats enter and leave your attic vents at or just after dusk

If you notice these signs of a bat visitor in your home or business, be sure to call us at Environmental Pest Management  immediately. Do not attempt to evict the bats on your own.

Depending on the time of year, you may inadvertently seal a bat into your building because it’s hibernating and you’ve closed the entry point. If the bat is female and raising flightless pups, you may also seal it and the babies into your home if you close entry points at the wrong time.

At EVP, we are well-versed in bat behavior, hibernation, and mating/birthing seasons, and can advise you on the best course of action once you discover you have one or more of these fantastic critters playing house with you.

Even though you surely don’t want these small, furry, somewhat creepy roommates to live with you permanently, the good news is that they are not rodents and will not chew on your walls, roof, or other home materials. They make their way into buildings to hibernate or colonize and raise their young exclusively.

When You are Ready to Evict Your Bats Humanely, Call the Professionals at Enviromental Pest Management

Our primary goal, no matter what pest you need to get rid of, is to provide you with a safe, humane solution for both you and the pest. With bat removal, we want to rid your home of the bat and return it to a habitat where it can keep doing its job uninterrupted–which is removing insects from the air and serving as food to other predators in the food web.

Since every building and every infestation are unique, we travel to your place to have a look at the situation before giving an estimate. Cost of removal depends on the number of bats in your home, the structure of the building, and the approximate length of the infestation.

Once we see what we’re dealing with, our quote will be precise and cost-effective, so you can make a quick decision to end the infestation and get on with your life, and the bats can move to more “natural surroundings” and continue to do what bats do best.

Call us at Environmental Pest Management Today for a free estimate and reclaim your home while sending bats out into their natural habitat so you can enjoy nature where it’s meant to be–outside!
