To control the varroa mite, formic acid is an option. Formic acid has the property to kill the varroa mite both in the capped brood and on the adult bees. This makes it suitable to apply just after the last honey harvest and before the feeding of the bees for the winter period. You can use a short-term treatment or a long-term treatment.
