we use a mixture of drone brood trapping and fall-treatment with formic
acid. In essence we place a cloth or fiber(whatever), which has been
saturated with a measured amount of formic acid, in the hive and let the
acid evaporate from that. It is very effective against both pests. No
residue in wax or honey, but it may kill a weak queen now and then.
Apistan, on the other hand, leaves residue in both wax and even in the
honey. It also bad for the bees' immune system - lowers it. The utterly
perverted and immensely stupid practice of using Terramycin is prohibited here.
