Thanks for reply Paul H. I'm trying to decide if I should take the time/trouble to build this thing. Seems you've already refined an effective method. Do you think adding HBH to your application would be possible? Efficacious? I've got this itch to try this fumigator, just to see the results. My caution arises from the long apparent lack of wide spread use or knowledge. Just a little PNW beek trying to follow data/experience.
