Can Checkmite plus kill honeybees? I had a terrible SHB problem. I put a few strips in each of 2 supers, upper and lower, 8 frame deeps. I have noticed a couple dozen dead bees in the front of the hive (on the ramp) a couple of days later. They were all small bees, like nurse bees. It might be just coincidence and house cleaning from the winter. That's why I thought I'd ask here.
Thank you in advance for any ideas, advice.
