I'm not sure if this goes in this catagory, but here goes.
I just found hundreds of dead ants in one of my flowerbeds in the yard where my hens free-range. I have not used poison in there for over a decade. Last spring, '08, I put down diatomatious earth along the whole bed because of ant colonies there. It didn't work. I find it hard to believe that more than a year later, there could be a residue that would suddenly kill hundreds, if not thousands of them in one area. They are just laying on the surface.
Does anybody have any idea what could have caused this and if I should be concerned for my hens that have free-run of the yard? I don't even know how long they have been there. I'm sure it's been less than a week, or the rains we had would have washed them away.
