Apiguard, Varroa Mite Medication

This relatively new medication from Europe is gaining popularity among beekeepers.  The active ingredient is Thymol, which is an essential oil of thyme.  It comes either in a 10 pack to treat 5 hives, or a pail to treat 30 hives.  It needs warm weather to be effective, so timing of treatment is important for those in cold climates
