"These hives tested only 2% to 3%, but when multiplied by thousands of bees they add up. I was always under the impression that Formic didn't really kill many phoretic mites.
"I guess it does !!!!"
Fred Putnam responds by saying "Besides killing mites in capped brood, Formic kills phoretic mites (the few that are running around unattached to a bee) and ectoparasitic mites (the bulk of the emerged mites that are attached to the bees.)"
Still time to test and treat. Please watch Fred's Mite Management, Counting & Treatment video for details.
