The hives are FULL of bees and seem to have expanding populations.Id be interestred to know to. I just purchased two FHB traps and currently have them set up on my hives....
Here is my theory: The adults hang at the top of the hive and end up in the oil when entering the hive. The larva migrate down and end up in the oil?Yes you should be catching Adults in the oil I did within 20 Min. there were adults in the oil never found any larva in the hives.
Absolutely covered. FULL of bees. I will look Wed to see if they are concentrated on a frame or perhaps all are being driven to the bottom?I'd inspect to see what frames the larva are coming from and freeze them. Are the strong hives able to keep all the frames covered?
