There are so many treatments to counter varroa mite infestation. Cultural approaches have been found to be effective and this include practices such as: purchase of mite-resistant honey bees, providing a brood break, and the use of small cell comb as a bait for the mites. Other treatment methods include mechanical treatments such as powdered sugar dusting, screened bottom boards, and removal of drone broods (cells most targeted by varroa mites). The final option is the use of soft chemicals to counter varroa infestation. It helps annihilate the mites just before the onset of winter. Oxalic acid, being a naturally occurring compound is derived from plants such as spinach, rhubarb, beets, and kale. It takes various forms which could be powder or vapor. It is best suited for an integrated varroa mite control since it does not penetrate the cappings. It is thus useful during broodless periods.
About the Product
This is a 100g oxalic acid package for treating varroa mites. It is delivered in 5 packets with each containing 20 grams of the product.
The specially formulated solution helps treat the space between the frames of the beehive, disinfecting and ridding harmful mites. It also helps get rid of mold and pathogens from the beehive.
Oxalic acid can also be used to clean and restore poly and wooden hives to their original color.
Application and Efficacy
The 20g oxalic acid powder should be mixed with 1 liter of warm water. Use approximately 5 to 10ml of the mixture to treat each of the interframe space.
It should be used 3 times during spring, within intervals of a week. During fall, apply the mixture after the honey has been collected and when temperature levels are not lower than 15 degrees Celsius.
You can also mix 100g sugar, 7g oxalic acid, and 0.5 cups of water. Apply the mixture at the rate of 5ml per hive.
The use of oxalic acid is effective in countering varroa mites but it should never be used as a standalone treatment option. It should also be used in moderation. Too much of the substance can harm the honey bees. It will crystallize in the mid-gut of larvae bees leading to a high mortality of larvae bees. It also affects the longevity of workers when used in excessive amounts.
Overall, this is a potent treatment against varroa mites. It does not affect the quality of honey for consumption since it is a natural formulated substance.
