Asked and answered but you may have missed it. (see post 085789)

> 1.   Is there any contamination of honey if the combs are sprayed with B401
> Bt (aizawai)?
None to worry about.  The strain of Bt in question is fatal to wax
moth, inconsequential to humans.  No worries to humans.  Honey
contamination is a non-concern.

> 2.  What is the downside of using Bt (aizawai) v. paradichlorobenezene?
Bt: Cost and availability (although the tip of diluting Xentari (a
powdered form of Bt widely used by orchardists) 4 teaspoons/gallon
addresses the later) and labor intensive.
PDB: Cheap, easy and a carcenogenic.  It really has no place in
beekeeping (my opinion).

> 3.  Why isn't Bt (aizawai) regerstered in the USA?
Either the company ownership changed or prior authority expired but at
some point it disappeared from stock and has never returned.
