Other Pests We Treat
Most spiders are small, inconspicuous arthropods which are harmless to humans. Their beneficial role in keeping insect populations in check far outweighs the hazard posed by the few spiders that occasionally bite humans. Very few of the 100?s of species of spiders in the Upper Midwest can hurt people. Only two groups–recluse spiders and widow spiders– are considered poisonous to humans.
Jumping spiders, wolf spiders, and some other spiders worry people who mistakenly believe they are seriously poisonous. Although these spiders are often large, hairy and formidable-looking, their bite is typically less harmful than a bee sting. People who are extremely allergic to spider venom, though, react severely to any spider bite.
All spiders are venomous but only rarely are they poisonous. All spiders can bite but very few will choose to do so. We receive countless calls and inquiries every year about diagnosed spider bites with the common comment being.. ? My doctor told me it was spider?? In almost all cases the actual culprit is something else. Mites, ticks and a myriad of other bugs are more likely the sources of those itchy red marks. Keeping that in mind, we approach the control of spiders by treating the source and looking at control measures instead of total elimination. We look at ways they are accessing a home through cracks and crevices and openings from the outside and try to solve the problem non-chemically if possible. A tube of calk or treatment with a good botanical repellent pesticide can do wonders in keeping spiders out of doors. Some species will set up housekeeping indoors and among that group, we find the cellar spider, common house spider and yellow sac spider leading the list.
When homes are located next to bodies of water or in heavily wooded areas, a good approach is to do an external application and to treat the siding of the home with a botanical pesticide that will prevent web building to an extent. It is not possible to prevent some web building as spiders are very resistant to the effects of pesticides due to fact that they spend so little time in actual contact with the homes surface and so much time on the webbing they have built.
