Inspected today. Took the top off my weaker hive first. Noticed a grub half wrapped in a paper-like material in between two top bars. It's a TBH and it couldn't get in but I was worried it might be a wax moth larva. It was gray, fat, and about an inch long. I dropped it so I don't have a picture. Inspection revealed no kind of damage or other larva but the hive just doesn't seem very strong. Lots of traffic in and out but not much pollen coming in. Neither hive will take sugar syrup so I assume there is a flow. Other hive has built out a whole bar plus the rest of their nuc frames. This hive hasn't even finished it's nuc frames yet.
Any thoughts?
Red Flag, Red Flag, Red Flag!!!!
If you could get a hold of some certan, I would asap, and spray all frames both sides. If your hive is weak as you say this is when wax moth will invade, and when they get a foot in the door, the hive is doomed.
Take action now before its too late!!!
