Oxalic Acid
Compact tub is a great addition to the kit.
Oxalic acid is an organic compound found in low concentrations in peanuts, pecans, wheat bran, chocolate and many other foods we eat. It is what gives these foods a slightly bitter taste. In high concentrations oxalic acid is poisonous and extreme care in handling the product is needed.
Oxalic acid is 70 times more toxic to varroa mites than bees. For more information Go to http://scientificbeekeeping.com/oxalic-acid-questions-answers-and-more-questions-part-1-of-2-parts/ to learn more.
