Hi Juanse and all
This treatment was done in late Sept/Oct when, although brood rearing
would be diminishing, young bees would be emerging daily thus the
mite levels would still be increasing. I believe that because of the
low level of formic in the hive, the mites don't get a lethal dose
until the 5th or 6th pad. Miteaway II single use pads, however, with
250ml in the pad get an earlier kill according to the OBA tech
transfer team.
