It was previously sold under the product label – Certan. It was labeled for use in bees when available here. It is no longer available in the US so it's not technically labeled here anymore. Probably not enough money to made here for the trouble of keeping it registered. You can read about it here: https://www.vita-europe.com/beehealth/products/b401/

The same thing with Thuracide BtK.It kills the very same type of moths as the BtA does but not labeled for honey bee hive use.

Bacillus thuringiensis var. aizawai (Bta) is what is used for wax moth larvae prevention on frames, XenTari is the name, OMRI listed safe. You can still get it here in the USA $26/lb. Amazon doesn't carry it anymore.
