I had every intention of checking on the bees. I’d gotten the smoker out and everything. When I went to open the plastic bin we keep the bee suits in, however, I found some unwelcome guests. They were everywhere, and the bee checking had to be postponed.
It wasn’t hard to find the source of the problem. We were storing the bee suit bin on top of another bin with some old frames of comb in it. And those frames, wouldn’t you know it, were completely full of wax moths.
Wax moths are a perpetual threat if you’re storing used comb without bees to protect it. Fans of the blog may remember that our hive was infested with wax moths last spring, after it was abandoned. Wax moths are rarely a problem in active hives, because the bees will drive them out before they can take hold. But if the comb is unprotected, like in the empty hive or the shed, moths are almost certain to move in.
Despite their name, wax moths don’t actually eat wax. A frame of unused foundation in the same bin was untouched. What the moths like is the thin, protein-rich skin that’s left behind on the cell walls by the bee larvae when they emerge as fully formed bees. Think of it like a bee amniotic sac. Moths lay their eggs in the wax, and those eggs hatch into grubs that burrow through the wax, feeding on these old protein skins.
Because they’re disgusting.
I thought the bin we were keeping the frames in was tight enough to keep the moths out. I thought wrong. Here you can see a few of those little grubs on the move.
And here are some adult moths.
Will and I dragged the bins outside to clear them out. We wiped out all the bugs and their bizarrely stretchy webbing.
The moths clearly started in the bin with the frames, but they’d been migrating. I found a few little cocoons in the bee suits.
I picked off all the cocoons I could find and shook everything out. For good measure, I took the suits home and washed them. I sprayed the bins down with the hose and let them dry in the sun. I’m pretty sure we’re moth-free.
As we were working, a few of the bees came over from the hive to see what we were up to. This one found a single globule of honey on one of the frames.
Some others flocked to the honey that dripped out of the frames onto the ground. They will have drunk as much as they could hold, then carried it back to the hive to store.
This wasp showed up for the free food, too.
So what became of the frames? I didn’t want to keep them around so full of moths, but I couldn’t stand the idea of throwing away all that good wax. I brought the frames home and tried to render the wax in my kitchen.
Stay tuned for that tale of hardship and woe.
