In the UK where, generally, the queen is kept below an excluder wax moths aren't a great problem. They aren't very attracted to comb that hasn't been bred in. This afternoon I was loking at a hive where the owner has left a beer mat soaked in Certan (BT) in the tray inder the mesh floor on the theory that wax moth larvae will chomp on it as the next best thing to a soft piece of wood. Can one of our Danish contributors tell us whether wax moths are a problem there? It is the practice in that country to renew brood combs annually and I am guessing that this will reduce the success rate of wax moths.
