WTF is This?!?

Joe, at our shop in Golden the wolf spiders would creep or is it run into the shop. The bodies at least as big as a quarter. They never walked out if I saw them! I hate them. When I was living in Westminster I used to get black widows all the time in the garage, let me tell you, brake cleaner or paint usually kills most spiders I attempt to kill however, it doesn't touch or bother the widows and believe me I have tried it on quite a few. There is only one way and that is to squish them with something, you know they are dead then!!!!
