I live in Windsor Ontario Canada. Yesterday I found a spider in the carpeted side of my basement. It was underneath a large toy in a corner. I have found this type of spider before in this room.This is also the playroom for my kids (yikes). I will try to get a digital photograph for you. It is darkish brown but not uniformly. It has some sort of markings on the back which were lighter brown or beige than the rest of the body. I thought it kind of looks like a skull. It was not a huge spider like a wolf spider but I wouldn’t call it small either. The body was bulbous. The basement is not what I would call wet, but it can be damp down there, with laundry facilities and storage nearby the playroom. Any ideas? I hate to spray because I am terrified of introducing those chemicals into my home, especially with the kids, but what are my options if it is a harmful spider like the brown recluse I’ve been reading about.
Not to be an alarmist, but it does sound like you might have a Brown Recluse, Loxosceles reclusa. There is plentiful information online, including this site which provides the following description of the Brown Recluse: “Adult brown recluse spiders are soft-bodied, yellowish-tan to dark brown, about 1/4 to 1/2 inch long and have long, delicate grayish to dark brown legs covered with short, dark hairs. The leg span is about the size of a half dollar. Distinguishing characteristics are the presence of three pairs of eyes arranged in a semicircle on the forepart of the head and a violin-shaped, dark marking immediately behind the semicircle of eyes with the neck of the violin pointing towards the bulbous abdomen.” Here are a drawing and photo from that site.
