Where did you get it?

The new name under beekeepers products is Certan wax moth Larvicide. It’s a little pricey even for bee products @ around $35+ for
5 oz. Someone had to pay the registration fees. In the old days there is rumored people have used Xentair, b402, certan b401 all are a targeted pesticide that some of them developed for cabbage worms. Does not harm bees. It is Bacillus thuringiensis.

search xentari. 7 springs farm supply has it for 25.00 per pound. there are different versions of B.T. not all work for wax moths. dipel is for cabbage worms. i talked to the manufacturer & it doesn't work for wax moths. i researched finding one that works for hive beetle larvae but never found one.
xentari was approved for bees. the approval expired & they weren't making enough money off the bee side so decided it wasn't worth investing in getting it reapproved. it does work but it will not safeguard frames from hive beetles so freezing & other precautions need to be taken.
