Found this in the basement of my duplex in West Michigan...not a huge fan of spiders. Is it dangerous? Should I do anything about it? Any help would be great. I was too afraid to get any closer to it so this is the best picture I could get haha.
Any idea what this MI spider is?
The only medically important spider in Michigan is the black widow spider, and this isn't one of those. It might be a common house spider, Parasteatoda tepidariorum - http://www.spiders.us/image/parasteatoda-tepidariorum-31/
