Re: If Oxalic and Thymol are harmless to bees and toxic to varroa...
I suspect "these things" are not harmless to bees like the title suggests, but instead work like chemotherapy. In other words, oxalic, & thymol kills the bad stuff, (mites on your bees like chemotherapy kills cancer cells inside you) only all three kill the bad stuff just a little slower (hopefully) than they kill your bees or kill you.
