As a new hobby beekeeper I have questions about Apistan. Does it work as a "fumigant" or does it work by "rubbing off" on bees that pass by? By the former mechanism, what is the danger of Apistan residue (after pulling the strips)--if there is any-- in the two bottom deeps contaminating the honey supers? By the latter mechanism, can the bees transport Apistan on their bodies to the honey supers? Also might the bees move potentially "contaminated" honey from the bottom deeps to the honey supers, eg to make more room for brood or pollen? Finally, what are the health dangers of Apistan--they are not described on the packaging. -Allen G. Meek Allen G.
