Thanks for the information. I had one of these in my bathtub and was able to catch it is 2 plastic cups and removed it to my mudroom. Earlier in the week I had seen 2 spiders in my bathroom. Does the centipede eat spiders? Is this the food chain in action?

I live in Northeastern Illinois--30 miles north of Chicago. We have quite a few of these, but has anyone ever seen these when they're 3-4 inches? Is it another species? They have so many legs that we call them toupee bugs. Since we live right on a creek, these things are in the house all the time.

Scutigera coleoptrata (L., 1758). This is believed to be a European species that has been introduced into North America by man and now occurs throughout the continent. It is often found inside houses in damp, cool spots, like in bathtubs, sinks & drains, and cellars.

I found one of these creepy things hanging from a web outside my
house i've never seen anything like it ,it really gave me the creeps!i'm from cumming georgia.U.S.A

This is a House Centipede, Scutigera coleoptrata(1). Keep them around, they get rid of the pests :)
