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.

Aaron Morris - thinking the archives are invaluable!
