VarroxSan – 60 Strips

VarroxSan is the first legally registered mite treatment in the U.S. that allows oxalic acid treatment through the use of extended-release strips. These strips kill varroa mites over time as the controlled release of VarroxSan’s active ingredient, oxalic acid, is taking place.

VarroxSan is in stock now and can be shipped to most U.S. states. PLEASE NOTE: Due to state restrictions, we are currently unable to ship VarroxSan to the following states: CA & HI

Instructions for use: *You should always refer to the EPA and manufacturer’s labels for full details and complete instructions for use.* Four strips of VarroxSan are used for every 10 frames of brood (or 1 strip for every 2.5 frames of bees in the brood nest). To apply treatment, simply fold each strip in half and drape over the top bar of a brood frame. After 52 to 56 days of treatment, remove strips.

VarroxSan works best when added to hives in the summer or autumn months, but not during the period of honey flow. There is no temperature restriction, but VarroxSan works through contact and is most effective when the external temperature is above approximately 15°C (60°F) and the bees are actively moving throughout the hive.

The distribution of oxalic acid relies on bees moving it around and coming into contact with other bees within the hive as they do when performing hive cleaning and other housekeeping tasks. This type of activity increases as external temperatures rise, so applying treatment during these times ensures a better distribution of the oxalic acid. VarroxSan can be used with honey supers in place, but application during active nectar flows should be avoided. This is, however, permitted if absolutely necessary.
