Now that I think of it, I can't find my 8 legged room mates. There was about 30 maybe even 50 little black spiders on my window last summer. I swore they had red under their butts. I never found the adult ones . But last summer I had hundreds of earwegs in here, I hate them soooo much. They always fall from the celing & land on my face at night & scare the crap out of me. But on the + side, the fish had a great meal.
