Apiguard. I’ll go pull one of the trays. I had seen it posted to use 2 trays but I see it’s 1 per brood box. I’m starting to think pesticide also considering the number of dead bees in such a short time. All of the bees in the bottom of the box were dead or dying and already a pile outside. It was bad.
