Last week a novice beek friend who lives in Rhode Island sent me pics of the deeps and frames that he had stored in his shed earlier this year. He hadn't used BT even after my strong urging. Now those boxes and frames have been burned. Right up to the time when the deep was about to go into the fire and just two days after blasting them with a strong water hosing, a dozen or so white worms were continuing to emerge from the deep holes they had bored into the wood. The moth larvae had finished devouring the wax so they altered their diet to include wood. The birds and chipmunks thoroughly enjoyed eating the worms that had been blasted off with the hose.

I would say that was a proper infestation.

I'm sure they now realize how inexpensive and easy it is to apply bt. It has pretty much become a habit for me to spray any frame before it gets stored. Even if I think it will just be for a couple weeks.

Boxes damaged by wax worms are unsightly, but they are still usable. If looking at the damaged area offends, use painters spackling compound to fill the indentions and then paint with a good quality exterior latex paint.

The box and some of the frames were burned mostly out of embarrassment. He didn't want other beeks to see his poor decision in ignoring sound advice. I hope he's reading this.

I was given boxes that were every bit as bad as those. They cleaned up fine and now have colonies in them. Most of the frames were not worth saving as they had not been glued together in the first place. Interesting how they build their cocoons between the box and the end bars but not so much on the sides.

And a follow-up to alf1960's question - does it have to be BTa or is the more normal BT I can get from Home Depot or Tractor Supply good enough?

Alf- BT is bacillus thuringus or something very close to that. It's at every garden center and used for moth control. It gets heavily diluted with water and sprayed with a spray bottle.

Bta and Btk sold at garden centers will kill the same family of moth.Lepidoptera and doesnt harm bees.I have used both for over 38 years with good results.

I believe the general thinking is that brood comb isn't safe without some protection. Comb that has only had honey in it is safe to store as long as the bees have cleaned it up a before storing. That's what I've observed as well.

Last winter I placed my spare frames in a freezer for 2 weeks, then in an air tight bag over winter. Before using I placed them back in the freezer for 3-4 days.
Is that acceptable also?
I know, I know, typical question 😃

I freeze frames too, before storing. But I've had moths chew through black plastic garbage bags to get at frames in my garage. This was brood comb. I plan to use BTa moving forward.

What Snapper said +1.
Be aware that because pesticides are regulated - the label is the law.
The states regulate permissible uses, as example, remember that OA usage had to be permitted state by state.
The labeling process is costly, beekeepers are a small part of the market so manufacturers have no incentive do the permitting.
Also XenTari is not labeled for usage with bees.
The label lists vegetable and fruit varieties and numerous caterpillar types but not bees, hives, comb storage etc.

I will add that many people will say that they will also infest honey comb, not just brood comb. Has not happened to me, but some here will strongly disagree that they only use brood comb. J
