I didn't know where to post this so please feel free to move it where it may belong. In my searching today for Jap Bettles for my hens I discovered that my Curly Willow has what I think are Aphids. Quite a few branches are covered with these tiny bugs. My question is what can I use to kill these bugs and it still be safe for my chickens? Would DE work. I read some place in BYC that someone made a solution and can use it as a spray. My bag of DE didn't specify which bugs it would kill, but I do remember something about exosceleton. I don't think these bugs have that. I don't want to use a poision because the chickens love to scratch under this tree. Any sugestions? I posted a picture below. It's kinda fuzzy tho.
