These strips are a great new tool in battling the Varroa Mite. Developed
by working with beekeepers all over the world, this new strip
formulation of formic acid not only kills adult Varroa mites but also
kills 95% of the Varroa under the cappings. This treatment consists of
simply laying the strips across the frames for only 7 days in daytime
temperatures of 50-92 degrees F. It contains no residues and it can be
applied during a honey flow. Can be left on the hive for the bees to
dispose of or the strips can be removed and composted.
