Save your colonies! Everything you need to know about anti-varroa fighting and protecting your bees

The Varroa destructor, more commonly known as the varroa mite, is the sworn enemy of beekeepers. This tiny mite, barely larger than half a millimeter, attacks bees by feeding on their hemolymph (equivalent to blood in insects). It thus considerably weakens colonies, making them more vulnerable to diseases and harsh weather conditions. Without intervention, a varroa infestation can annihilate a hive in just a few months.

Fortunately, there is an arsenal of effective methods to fight against the varroa mite and protect your bees. This article presents in detail the different anti-varroa treatments available, their advantages and disadvantages, as well as practical advice on how to implement them safely and optimize their effectiveness.

Varroa destructor: a formidable parasite for bees

Varroa destructor is an external mite belonging to the Varroidae family. Originating from Southeast Asia, it has spread throughout the world during the 20th century, becoming a formidable parasite for Apis mellifera, the honey bee most commonly known as the honey bee.

The varroa mite's reproductive cycle is closely linked to that of its host. The mite reproduces in the bee's brood, taking advantage of the larvae's development to lay its eggs. A female varroa can lay up to six eggs per day, and its offspring feed on the hemolymph of the developing larva. Once mature, the adult female mites leave the cell and attack adult bees.

The consequences of a varroa infestation are disastrous for the health of bees. By feeding on their hemolymph, the varroa mite transmits viruses and weakens their immune system. Infested bees become more vulnerable to diseases, live shorter lives, and see their flight and foraging abilities diminished. Ultimately, an untreated infestation leads to the collapse and death of the colony.

The different anti-varroa treatments: advantages, disadvantages, and points to watch

In the face of this threat, beekeepers have several treatments at their disposal to fight against the varroa mite. Here are the main ones, with their specificities:

  1. Formic acid: an effective natural treatment
  • Active ingredient: Formic acid is a naturally occurring organic acid present in ant venom. It acts by contact, destroying the protective cuticle of the varroa mite and causing its death.
  • Advantages: Formic acid is a natural and biodegradable treatment, safe for adult bees and honey. It is easy to use and does not require specific equipment.
  • Disadvantages: Formic acid is an irritant for the eyes and respiratory tract. It is important to wear personal protective equipment during its application. Its effectiveness may vary depending on the ambient temperature and the targeted mite strain.
  • Points to watch: Formic acid comes in gel or diluted solution form. Strictly follow the dosages and application durations recommended by the manufacturer.

Powdered mallow:

  • Active ingredient: Not identified (probably a combination of natural compounds)
  • Advantages: Natural, safe, repellent.
  • Disadvantages: Moderate effectiveness, regular application, difficult to find.

Oxalic acid:

  • Active ingredient: Oxalic acid
  • Advantages: High effectiveness, rapid action, broad spectrum, biodegradable, low cost.
  • Disadvantages: Toxic to bees, irritant, risk of burn, not suitable in the presence of brood.
  • Points to watch: Dosages, application time, individual protection, cautious handling.

Bonus: The Revolutionary Stop Varroa Treatment

The Varroa Treatment stands out for its unparalleled effectiveness, completely eradicating these parasites. It is also suitable for organic beekeeping. Stop Varroa poses no risk to bees and preserves the quality of your honey, without contaminating it. The Stop Varroa treatment, of natural origin and easily manageable, ensures complete success. Its use simply consists of individually lifting the frames and spraying the product on their two faces. In less than 24 hours, the entire varroa colony will be annihilated.


Choosing the most suitable anti-varroa treatment for your context and applying it wisely are essential to protect your colonies. Regular monitoring of hives is crucial to detect infestations and act accordingly.

Do not forget that the fight against the varroa mite must be part of a global strategy for managing the health of colonies, combining anti-varroa treatments with healthy beekeeping practices.
