I have a hive with quite a few small bees with a small abdomen. First thing that came to mind is mites. I treat with thyme sugar water, and check my SBB about once a month. I find very few mites I don’t even clean the bottom board. It's been 6 month since I cleaned it. Every thing is still there a few dead beetles and a few dead moths that I smashed over that last 6 months, cappings and about 100+ mites.
Two hives out of 18 have these small bees. All the hives have same mite treatment.
Is it mites?
Are my treatments not working?
