So, there are massive roaches in my backyard. I think the duck feed is attracting them, as well as my former neighbors. The ducks eat them, but I can't stand the thought of those things living in my shed. Luckily they haven't taken over my house, though I fear that may occur with winter's approach. I have some professional grade pesticide I could use indoors, but I'd like to get them out of my yard. I was thinking diatomaceous Earth, as that seems to be safe for chickens. Any thoughts? Anyone else had this issue?
