We treated for mites on June 24; took mite readings earlier in June, but figured we would have to treat anyway based on our previous counts, so no use counting again.
However, during the Mite-Away treatment, we saw the following Mite drop on the grid bottom boards at the end of 6 days:
Blue – 70
Yellow – 43
Blue on Yellow Nuc – 16
They certainly needed treatment; following advice, we will treat again in August, and use vaporized Oxylic just after Thanksgiving.
Since we monitor the temperatures (and humidity) on the hives, you can see the effects of the Mite-Away treatment (shown below on the Blue hive) …. it really affects the bees…they seem to get out of the hive a lot…
