When inspecting my hive today, I decided to take a look at the plastic board underneath the screened bottom board. I didn't see any mites (thank God) but i did see some larvae that wasn't bees. I assume it was SHB. There wasn't much from what i saw. All of the larvae was 1/8"-1/4" long and was white. These bees have been treatment free for over 5 years and I want to keep it that way. Any advice on how to take care of this or if I should do anything at all.
I don't have any pictures of the larvae, sorry. But here is a picture of a frame of brood from my newly mated queen if it will help.
