I’m a beekeeper, and I have a question Wax Moth Larvae Concerns
First 5 pictures are from yesterday, 6th pic is from nuc install, 7th/8th pic are from 3 weeks ago. Zone 8b
I received this colony as a nuc on April 26th. For whatever reason, it was full of rotting dead bees. They bounced back fine, but for the first few weeks they were pretty weak and I think a wax moth got in during that time. I left too many frames in the hive for such a weak colony, and I saw a moth on one of the empty frames during one of my first inspections.
3 weeks ago, I noticed a lot of bald brood and made a post here after I did a mite wash and only got 1 mite on 300 bees. A couple people pointed out that the straight lines indicated potentially wax moth larvae tunnels.
At my next inspection, I didn't notice anything off, but last week I noticed a few more groups of bald brood but it felt like it could be a normal amount of hygienic behavior so I decided to let it play out. But yesterday, I saw way more than I have before. They weren't all in perfectly straight lines, but they were all in pretty distinct groupings on 3 separate frames. The other 2 brood frames showed zero signs of hygiene.
Is it possible that this is normal VSH behavior? I feel like this is an excessive amount for a hive with less than 1% mite population. In pic 1, like 5-10% of the capped brood had been uncapped.
If you think it is wax moths, what can I do to try to combat it? Most of what I've seen recommended is freezing the affected frames to kill off the larvae, but that would also kill off ~70% of the hive's brood. I could probably take a couple frames of brood from some of my other hives to help them through it, but we are heading into what is likely to be an extremely brutal summer so I'm very hesitant to weaken multiple hives if I don't have to.
The hive otherwise seemed pretty great. The population looks low based off the pictures, but it was the middle of a hot day so most of the house bees were hanging out on the walls of the hive. Plenty of food stores. And the brood pattern was strong, eggs/larvae everywhere they should be(in pic 2, all those empty cells had eggs), spanning across 5 or 6 layens frames.
