Dear MMDians, I had an idea.  Since I'm going to be using
shellac, I can mix in pretty much anything I want into the solution.
Woodworms and termites are a scary thing to me, so I was hoping you
all could suggest a number of different poisons to mix into shellac.

I figure that if one pipe or part of the organ has been attacked,
then best to keep all other pipes from being infected, so to speak.
So, what kind of poison would not harm shellac or wood (acidic and
basic properties would be benign) and be just all-out lethal to the
living?

Killin' them critters,
