Two of my hives are very clean. One especially is tidy, straight, and clean. The third just seems grimy.
The propolis is ugly grey and gooey/gunky and excessive. I don't seem any Nosema, or bee defecation. There are not any beetles, or wax moth larva or slime. All the comb seems normal, but the frames, especially the top of the frames is just dirty.
Today I say what seemed like a small drop of water on a frame. It was watery, not sticky, gooey, slimy, or stringy, and it was a grey, milky color.
This hive had beetle problems in February, but the population exploded last month and I rarely see one now.
It has swarmed twice already this pre-honey flow calendar year.
Ideas?
