Hi! Everone... I think that the mineral oil treatment is a great idea. We have to start to look for remedies from nature. This treatment could be used on ferral bees and would help keep the mite from reinfesting our colonies. At the same time the bees could be developing their own resistance to the mites, and this would not be an artificial medium which when the drug is gone the mites are back in full force on bees that are sick from both the mites and the drug. I noticed that formic acid really depressed my bees, and they slowed down in brood production. I took the pads off and the bees seemed to liven up, flying and multiplying faster. This mineral oil will make the mites sick, and at the same time have no effect on the bees and they will carry on in numbers and be stronger for it. Idea.. more bees = more of a chance to develope immunity. This is just a thought I had, I am a novice. Maybe we can brain storm on this? Debie from Canada.
