    Hey everyone, As you have seen before I am a bit of a oxalic acid nut and always want to figure out the best way to do somethings. I decided to use the ProVap 110.

    ...then why do these things kill brood, and not affect varroa in capped cells? After using oxalic vapor, one will often find brood at different stages of development is killed and disposed of outside. I have read that this can happen with some of the thymol products out there as well. And...
