For treatment of Varroa and Tracheal Mites Slow release formic acid is available in pre-soaked pads or you can purchase just the formic acid in a 4L jug. It is a slow release so it does not overwhelm the honey bees. The fumes do not affect the honey bees but makes the mites fall off of the honey bees. The concentration is 65% formic acid. This price is related to the 20 pad kit already pre filled with formic acid for your convenience. Please use two pads per hive. Place on opposite sides of the box and leave in there for couple weeks. ****Note: This product is for pick-up ONLY
