I noticed yesterday that the hive was doing house cleaning. Probably 15 or so pupae on the ground at different stages of development. I also notice maybe 5 or 6 emerged bees with deformed wing virus. I have two 8 frame deeps and a parcel 8 frame medium (medium: some frames filled, some not, foundation)
I treated with a OA vaporizer a couple of weeks ago. I'm not sure that I did it properly. The first treatment when I pulled the vaporizer out had a bee in the pan. The second treatment I stuck in from the backside where the oil pan slides in at, however it tilted and I'm not sure of the dose because of that. The third treatment was done correctly.
This is my first winter with bees so I don't know if I should expect to see this or not. I was concerned about applying the OA again because I didn't want to kill the bees. Any thoughts?
