THYMOVAR strips each contain 15g of Thymol, a phenol naturally found in thyme essential oil, widely used as a food flavouring and in cosmetics and pharmaceutical products. Thymol naturally occurs in   some honeys, such as thyme, lime tree or sunflower honey.
Upon release, Thymol vapour concentrations build up in the hive. These vapours are toxic to Varroa mites, but are not harmful to honey bees when used according to the directions for use.

Each pack treats 5 hives twice
