I've had big nests of Army worms move into some of my apple trees ,can't really use a spray because if they fall out the chickens might try to eat them .Doesn't seem like anything eat those nasty worms ,they will strip down a whole tree of all their leaves ,then they move on to another and do the same . any advice would be great ,thanks Dee Anna.
