formic pro leaflet Fight varroa and protect your honey. READY-TO-USE STRIPS THAT MAKE ORGANIC VARROA CONTROL EASY. Formic Pro is a brood-focused treatment that targets Varroa destructor mites where they reproduce: under the brood cap. The formic acid vapours penetrate capped brood to protect vulnerable developing bees from varroa mites. This organic miticide also kills dispersal phase (phoretic) mites found on adult bees.
