Oxalic Acid 140 g with  Dihydrate 99.6%. 

This crystalline powder is a treatment to control the varroa mite in honey bees. It can be used with an oxalic vapourizer or can be dissolved in sugar syrup or sprayed into the hive.

Apply in late fall for best results. Do not use when brood is present.  This 140 g will treat approximately 80 hives.


Always wear impenetrable  gloves & protective clothing as you don’t want to get the chemical on your skin and wear a full mask respirator with cartridges rated for use of organic acids.
