Have you ever used Formic Pro on top of 2 deep body hive instead of between brood boxes? If so, is it effective and safe?
I do not recall this as being the recommended application method for FormicPro, nor for the companies' predecessor formic product. None of the instruction pamphlets which come in the package describe this method but I haven't keep them all and none are dated.In 2020, I followed the recommended placement (honey super, pad #1, deep, pad #2, deep, bottom board with the entrance fully open).
NoCan we all agree that formic pro is not a great product?
