One should be able to do a test.
Do a mite count with alcohol wash or icing sugar. Pick a hive with a >3% mite count.
Remove and clean sticky board in a screened bottom and recoat with oil. Do a mite count on sticky board after a couple of days.
Remove and clean and coat sticky board. Fog and do a mite count on sticky board after a couple of days.
Again do an alcohol wash or icing sugar test.
???? Min of two days between tests and a max of a week.
Plan to give it a try but will be 3-4 months till warm enough
