Last thursday I opend one of my three hives and found an large infestation of wax moth larve. They were everywhere by the hundreds, I ordered some BT, it arrived late yesterday, so early this morning, I mix up a quart of BT, opened the hive and the larve were no place to be found. I did find some webbing on one of the frames, but very little. I sprayed the frames, bees and all with a light spray anyway. I was unable to find the marked queen after twice checking each frame. It is pobbible she was on the inside of the body. Today I reduced the hive to a deep with my best 9 frames. It is a weak hive, the best thing is if they " whacked" the queen as she lays very spotty anyway. It's very late for all of this to happen. But, what happened to the hundreds of larve that was there 5 days ago? No moths observed flying around.
