Re: Another varroa question
Agree with that.
As a part time job I test mite levels in hives as part of our governments disease surveillance program. There are often differences between one hive and another.
Very occasionally, we'll do a yard where the hives have moderate or major infestations, but there will be one hive with virtually nothing. I've considered approaching the owners of some of these hives to see if I could use that queen as a breeder, but so far haven't had time to follow through on it.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
