Usage Instructions

Use up to 4 VarroxSan™ strips in a brood chamber, placing them between brood frames. Ensure the bees can walk on the strips. Leave the strips inside the hive for 42 to 56 days, then remove. If after 42 days bees aren’t in contact with the strips, reposition closer to the cluster. Strips must be removed after 56 days.

For colonies in double brood boxes, place four strips in the lower chamber and up to 2 additional strips in the upper chamber. For medium-frame brood chambers, use half the dose. For two medium boxes stacked together, treat this as 1 deep box. 

Detailed Description

VarroxSan is made from oxalic acid dihydrate (18.42%) and delivered in convenient slow-release strips. The fiberboard strips are designed for easy application, and each pack contains 60 strips, treating 15-30 hives. VarroxSan is a long-lasting, natural solution for varroa mite control, with each treatment lasting 42 to 56 days. It works best in the summer and autumn, though it can be used year-round under the right conditions.

The slow-release mechanism ensures a controlled distribution of oxalic acid, reducing the need for repeated treatments. Ideal for use during low honey flow periods, VarroxSan allows beekeepers to maintain hive health without worrying about environmental impact.
