At this time of year, we get a lot of calls about spider control!
But first the good news - those big brown spiders you see are probably NOT Brown Recluse spiders, as they are mainly a south central United States spider. Most likely, you are seeing Wolf spiders - there are 50 or so species of them found in Michigan. They are brown, have 8 eyes in a distinctive pattern, and can grow fairly large, up to 1.1 inches in size. But there are no real dangerous Wolf Spiders indigenous to North America, and if you do happen to get a very rare bite from one, at most it can cause some swelling, itching, but no long term or dangerous effects.
Black Widow Spider
The only real "dangerous" spider found in Michigan is the Black Widow Spider, which is easily identified by the "red spots" on their black body. Black Widow Spiders do have a toxic venom in their bite, but really only dangerous to small children. However there is more good news here, the Black Widow Spider is a very timid spider, and prefers to flee when disturbed. Bites from Black Widow Spiders are actually quite rare.
There are about 39 types of spiders found in Michigan, and two of the more common ones you can run into in your Grand Rapids home are Cellar Spiders ("Daddy Long Legs") which like to hide in our basement, and the black and yellow Garden Spiders that like to hang out under leaves and in your garden.
