Its too hot right now for apiguard in our area which will explain extra bearding, especially w/ reduced entrance. Take off feed, remove reeducer and leavew on apiguard. Dont stop now w/ meds. The dead pupae are eitehr from meds, or mites or inspection. If they are chewed up, mites, crushed from inspection, whole from meds. in all likelihood. After apiguard is on for a few days, you can feed and reduce again when weather cools a little and the fumes decrease. I was going to put on meds, but am now waiting a few days for cooler time.
