Disturbing behavior this past week, looking for feedback (video and description)
This hive has been a super strong first year colony. I harvested ~70 lbs of honey last week and started treating with OA vaporization as soon as I took the supers off. Mite counts were 0 in June, 3 mites out of ~400 bees in August and then last week before removing supers I did a full inspection and saw 4 mites on nurse bees just while looking over frames – alarming.
The girls have had 2 OA treatments in the past week (4 days apart) and I plan to keep treating every 4 days for a total of 7 treatments. Since I started treating, the weather has gotten much colder (30s at night) and each morning starting 2 days after first treatment, this is what I see outside the hive (see video). Weird thing is after it starts warming up more, by about 11am, most of those bees are gone and everything looks normal again other than ~10 dead bees scattered in front of the hive. Some of the dead ones have their proboscis' sticking out with lots of fluid around the body. Other bees are just really lethargic and seem to want to crawl up to high ground. Just standing there watching, I get several bees crawling up my shoes and pants – never seen that before. But like I said, a little later in the morning and all of those lethargic bees are gone and everything seems normal again.
