Thanks! Normally I leave spiders, too, I just never go out at night. lol. But I have never seen Black Widows like we have here. They are huge! And I saw a huge one in one of the coops. But they are getting out of hand like I've never seen before. Now I find out that the Brown Recluse is in this area, too. I've got to do something, I just don't want to put something out there that might hurt the birds. And in the heat and humidity we're having I can't just take everything out of the coop, including all bedding, and spray with Raid or something. And this old playhouse has the double walls with plywood on the outside and paneling on the inside that has warped from the high humidity leaving lots of little gaps for them to run back into. So I have to use something with a residule effect, to kill them when they come back out. Grrrrr.
