Despite what I read on the EPA website, this fumigation thing is still a leap of faith, in both directions. It really does evaporate, because it's a gas and not a residue, like the old days. But that's provided you ventilate after treatment. And it's supposed to penetrate wood, etc. I hope the termites really are terminated. But that's all they'd be. Dead. This is just a temporary setback for those little critters. They'll be back. My house is too yummy.
So, after $$ and half the summer, I have an updated bathroom, a new door, a study area in the master bedroom, a well-ventilated crawl-space, new deck beams, a cleaned-up garage, and most of a dumpster's worth of trash hauled away.
