Does anyone know how serious the problem of hornets can be on my hive. I've set hornet traps around the hive, they seem to be very successful in catching European hornets and now Carrion beetles. Every day I visit my hive I kill a 5-7 hornets waiting to catch and fly off with my bees. So far Ive killed around thirty. Im hoping I can locate their nest and destroy it. Does anyone have any suggestions for this issue?
