    "Bacillus thuringiensis subspecies kurstaki strain SA-12"

    i think you need the aizawai strain for wax moths.

    Bt K is known as Thuracide.BtA you get a big bag and BtK is a small bottle.You will get more for your dollar with the big bag of BtA.

    A big bag would be fine, if it did not expire so quick, or in many cases was shipped past expiration date.

    FWIW Xentari is also not labeled for use in a bee hive.

    I got mine off the internet. The brand I got is Dipel Pro which is made by the same manufacturer as Xentari but much less expensive. It was shipped to me out of code but still worked well.

    I see a lot of BT's with this as the active ingredient:
    Bacillus thuringiensis subspecies Kurstaki strain SA-12 Solids, spores and Lepidopteran active toxins.

    Is this the stuff were looking for? Is this the Bt-A

    I also have used Bt-K (Monterey BT) in my gardens for the past 40 years. The worms eat the spore and get sick very quickly (within hours to 1/2 a day). They may still be alive the following day, but not eating anything until they die.
    I would think the Bt-a would work just as well in the garden, but I have not tried it.
    9 hives - 10 years (also had 7 hives in early 1970's) T as needed - zone 6

    Bacillus
    There are different strains (varieties) of Bt available that have been selected to control different specific insects. Bt-kurstaki (BTK) controls the European corn borer, tomato hornworms, fruit worms, cabbageworm, cabbage looper, spring and fall cankerworm, spruce budworm, and other caterpillar-like larvae. Bt-san diego (BTSD) controls early larvae of the Colorado potato beetle. Bt-israelensis (BTI) controls mosquitoes, black flies and fungus gnats.

    Bacillus thuringiensis -aizawai is used exclusively for the control of wax moth larvae.

    Thuricide is Bt-kurstaki, so it is the wrong strain. It is also in an emulifised pertrolium oil that you should NOT put on your comb.

    Bacillus thuringiensis -aizawai is also used on crops so it isnt exclusively for control of wax moths.Dipel powder isnt in an emulsified petroleum.Valent BioSciences the manufacturer will disagree with you.They have a wed site describing these.

    So have we established that BtK does _not_ kill bees? Has anyone here sprayed it on their combs and lived to tell the tale?

    I have used it for the past 6 years but ONLY for drawn out frames going into storage for the winter to protect them from any eggs that may have been layed while in the hive. I have never spray it on frames that are still being by the bees. It kills the caterpillar as it hatches from the egg and not the moth!
