In an apiary of 20 hives I am counting a mite drop of 4 a day in a couple
of hives. The remainder of the hives show no mites at all. I treated
with Checkmite exactly as recommended last fall and I use hygienic NWC
queens from Pat Heitkam. I would think by now I would be seeing much
greater mite numbers and wonder if I made a mistake. I thought that
spraying Pam on the plastic trays that go under the screened bottom board
I would catch any mites and prevent them from crawling off. Do you get a
more accurate number with the sticky boards? Is it possible that
Checkmite leaves a residual effect because it gets into the comb or am I
seeing an effect from the hygienic bees removing larvae that are being
attacked by the Varroa?
