What a mess, but I am wiser >for it now. made me wonder "Does Apistan, when used in a legal manner for control of varroa mite, have any direct activity against wax moth as well?" The active ingredient in Apistan, fluvalinate, is a very effective insecticide for control of many other caterpillars, including many that are in the same family as wax moth. However, I am unaware of any testing for this insect and the rates used for varroa may be insufficient for wax moth. Just wondering, as I can't find any other way to control existing wax moth infestations since Certan has dropped off the market. Whitney Cranshaw Colorado [log in to unmask]
