My neighbor gave me his old coop. It seems to be infested with tiny black ants. They are EVERYWHERE! I am also finding lots of eggs everywhere. I cleaned it out and sprayed everything down with a water/bleach solution. I also replaced some rotted boards. The ants are still all over. They seem to be coming out of the wood. The ones I sprayed died, but when I went back later in the evening there were still ants everywhere. What can I use to kill the ants that will be safe for my chickens?
