Forgot one...
There is (or rather, was) also a type of Bacillus thuringiensis that
attacked wax moth at the larve stage, but the company that sold
it declined to spend the money to re-register it in the US.
Folks in europe use it all the time.  Over there, it is called "BT-401".
Sadly, they can't sell it to US addresses.

I have no idea why the BT one can buy in the US to fight bagworm
and other pests similar to wax moth would not work on wax moth,
but I have not experimented with it.  Any biochem majors out there
that know details about the various types of BT?
