Haven't tried this, but heard of it and would use it if I needed to. A free range flock of Banties in the apiary. The gentleman in Florida that uses them says the chickens are crazy for the beetle grubs in the sands around his hives. So much so that he has to regularly grade the sand back into the pits they make around the hives. I'm sure it's not a cure all, but any natural control is great and I like chickens.
