I've heard some people say to stack them outside, exposed to the weather, and others say to put them in an airtight bag in the basement for the winter. Also, some people treat them with something for wax moths and others don't. Any insight and experience appreciated...

My frames are sprayed with BT when new in the beginning, after extraction placed back on hives for bees to bee cleaned. then stacked in open shed on solid floor { mice you know}
Next spring spray with BT again, { not really needed but too cheap and easy not to } and start over again.

Here we go with these abbreviations again lol. First it was DT now it's BT....I'll bite...what is it...? I typed BT into a search and came up with Bacillus Thuringiensis. Is this it?

Bacillus thuringiensis it is: A bacterium that attacks and kills the larvae of Lepidoptera (butterflies and moths). When the wax moth larvae feed on the sprayed hives, they ingest the the BT and it kills them. It has no effect on bees or on honey for human consumption and falls into the category of biological control agents, non-poisinous organisms that help to control pests. ;)

... can only find a product called "Para-Moth"
I'm not familiar with brand names, but it sounds like crystals of the same material "moth balls" are made of (para-di-chlorobenzene, I think).
Ive used them many times and they are effective--providing that you stack your hives solidly and there are no cracks for new mooths to sneak in after the crystals evaporate.

It doesn't say in the catalog what it contains, but I'd bet you're right, I had always thought that moth balls primary ingredient was naptha, but the key word here is THOUGHT. So, instead of paying big money for a "bee specific" product, why can't I just sprinkle moth balls throughout the area where I store the frames, inside a plastic "deck box" that I bought at the local home store. I have one dedicated to frame storage, and it is weather tight, but probably not moth tight.
Thanks ef and Walt.

There are two different moth balls in the store. The paradichlorobenzene ones can be used. The other ones cannot. Of course, they only last a short time, where BT lasts the life of the comb.

OK
Thanks Iddee. I'll buy the right stuff. Didn't realize there were 2 different types. I thought moth balls were moth balls. Guess that's what I get for trying to do a job (thinking) without the proper tools.
That's why I joined this forum and why I spend so much time here.

thanks Iddee for pointing out that moth crystals are not moth balls. this seems to be a constant point of confusion. the first time you place moth balls in a stack of supers and come back to find them full of wax moths will reinforce this lesson <been there, done that.

with paradichlorobenzene you need to separate the stack about every 5 or so boxes with newspaper and add a tablespoon or so of the product (on the paper). after treating you then need to wrap the boxes in plastic or cover with a tarp... this just limits moving air thru the stack which vaporizes the product. in very active wax moth areas you need to unstack and retreat about every 45 to 60 days. there is some concern about the long term health effect of using this product since benzene is considered to be carcinogenic. para moth require any treated boxes to be air out (takes about 2 days or so) before placing back on a hive.

There are several subspecies of Bt., many are
not as effective. The subspecies Aizawai is the
one that was in Certan. The only product I am
aware of that was certified for bee use.

I switch to Agree WG awhile back as it also contains
the protein from Bt Kurstaki, and is more effective
that Xentari.

The product is invaluable in my orchard and garden
as it is inexpensive, and stores well (in dry form).

It is also rated Organic in agricultural uses.

Crazy that it isn't "legally" allowed for use on bee
colonies. But Paramoth is??? A carcinogen?? Go
figure.

If you are cheap (like me) you can get a block of urinal disinfectant from a janitor's supply... most are made of paradichlorobenzene. Chip a chunk off and apply per tec's post, above. Store the rest in a zip-lock in a sealed container. Seems to last. Kind of stinky in the spring, though, and I air mine out before using.

After my wax moth fiasco this year, I will be applying BT to all comb.

Darn, now You come out with something new !
I bought a 1/4 lb. of BT 4-5 years ago from you and still have a lifetime supply !!

Guess, I just have to live with it, AND no moths !

Good one. The old stuff is still darn effective, just
the new product is a bit better.
