So I treated three times since the end of summer - once with formic when the weather was good, and twice with OAV, once in Jan. and once in Feb.
I broke some drone brood yesterday, and I saw drone larvae with varroa on them. A few had one or two, and one had about 4.
Should I be worried? I feel like we all know that we are raising varroa with our bees, but I don't know if this is evidence of being over threshold.
I guess i really just need to do an alcohol wash to find out...
