Has anyone every used the Kurstaki strain of BT for wax moth control? I understand it is used in India and several Middle Eastern countries for this purpose. Apparently, Aizawai is the only type of BT that has been registered for wax moth control. Since it is no longer registered in the U.S. for wax moth control, and I only have paradichlorabenzine as a legal option, I was wanting to use the Kurstaki strain because I know it will not harm honeybees. The main question I'm asking is how effective has it been for you?
