Hi Guys, I've moved varroa free hives near infested ones and observed the same results. Within a few weeks, natural mite fall will be essentially the same. But here's something else to think about. My small cell hives were surrounded by hives that migrated from CA almonds. Two semiloads were dropped within 2 miles. The last remanents of them would be moved to out yards toward the end of May. And up to 400 hives would be placed around my small cell yard on about a 1/2 mile spacing. There are two commercial beekeepers who have grandfathered locations. And suitable bee habitat is scarce. Yet, my small cell hives thrived without treatment, even when hives surrounding mine were collapsing from varroa. Some of the surrounding yards would normally have 40 hives. And would be left with just a couple after the collapse.
