[Terrapreta] A few photos of the rice hull charcoal trial

[Kevin Chisholm]

Dear Jeff

When an Ant colony is attacked, they give off a cloud of formic acid 
vapor, to repel the attackers. Acetic acid "vinegar" is similar in smell 
  to formic acid.

Intuitively, there is a good reason to believe that vinegar from 
charcoaling could repel insects and varmints.

Best wishes,

Kevin
