I have a couple hives that I purchased as small cell nucs last year. They've been treatment free since then. The state inspector took a look at them on Friday and told me I have pretty bad varroa populations and the start of some European foul brood as well as deformed wing virus. He recommended Mite Away Quick Strips (formic acid) as a way to take down the mite population. I'd prefer not to do that, but I don't know of any other options that are in keeping with treatment free ideals. I can't afford to just let both of my hives die. Is there a treatment free option? I've read the Idiot's Guide to Beekeeping, and their section on varroa says "we don't have a mite problem". And that's it. Well great. That's no help.

Anyone have suggestions?
