Hi. I live in Michigan and was curious about this bug. I see them in the bathroom sometimes along the crack between the floor and the wall, they are very fast and hard to photograph,(I had this one trapped for about a week hoping he would die so I could get a picture). He is still alive although he did change from brown to a very light color and is about 2.5 cm long. Not as interesting as some of the other bugs you feature but I wonder what this one is and if he changes into something else. Thanks,
You have Silverfish, primitive insects and common household pests that are usually found in dark damp areas.
