What can I do to prevent Varroa infestations in my hives?

As a beekeeper, you play a crucial role in preserving the balance of our ecosystem. Your bees, by pollinating from flower to flower, ensure the pollination of many plants, thus contributing to the production of our food and the health of the environment. However, your hives can be threatened by a formidable parasite: Varroa destructor, commonly called Varroa mite. This microscopic scourge attacks bees, weakening them and making them more vulnerable to diseases. Severe infestations can lead to the death of colonies, endangering the survival of these precious pollinators and honey production.

Don't despair! Many solutions exist to prevent and control Varroa infestations in your hives. By adopting good practices and combining different approaches, you can protect your colonies and ensure the prosperity of your beekeeping activity.

  1. Early monitoring and detection: The eyes and ears of your hives

The fight against Varroa begins with careful monitoring of your hives. Be vigilant and inspect your colonies regularly for signs of infestation. Carefully observe the bees and frames for mites or their larvae, which resemble tiny brown dots. Also, pay attention to bees crawling on the hive floor, which may indicate a significant infestation.

For even more precise monitoring, several methods are available to you:

  • Alcohol washing: Dip a sample of bees in diluted alcohol and observe the presence of detached mites.
  • Brood sampling: Cut a piece of capped brood and examine the cells under a magnifying glass to detect mites or their larvae.
  • Use of Varroa traps: Install traps in the hive to capture adult mites and evaluate the level of infestation.

By monitoring your hives regularly and detecting infestations at an early stage, you maximize your chances of acting quickly and avoiding significant damage to your colonies.

  1. Chemical treatments

When Varroa infestations become critical, the use of chemical treatments may be necessary to save your colonies. Various effective products are available on the market, such as:

  • Formic acid: Applied in the form of gel or vapor, it effectively penetrates the hives and eliminates the Varroas.
  • Oxalic acid: Particularly useful during the winter when the bees are grouped together, it allows for effective colony treatment.
  • Amitraz: Distributed in the form of strips, it slowly releases an acaricide into the hive, killing the Varroas.

Attention: The choice of the appropriate treatment depends on several factors, such as the stage of infestation, the time of year, and the presence of other parasites. It is crucial to follow the manufacturer's instructions scrupulously and to take all necessary precautions to protect the health of the bees and yours.

  1. Methods of fighting Varroa without chemical products

Many alternative methods of fighting Varroa exist for those who prefer to avoid chemical products. These methods include:

  • Thymol treatment: Thymol is a natural compound derived from thyme that can kill Varroas. It can be applied in the form of gel or vapor.
  • Trapping: Varroa traps can be placed in the hive to capture adult mites.
  • The queen cage method: This method involves isolating the queen in a cage for a short period, which prevents the Varroas from reproducing.
  1. Stop Varroa: A revolutionary treatment to save your hives

Stop Varroa, an organic and easy-to-use treatment, promises a total eradication of varroas within 24 hours, thus guaranteeing the health of your colonies and the quality of your honey. Its simple application, redoubtable effectiveness, and respect for the environment make it a valuable ally for all beekeepers concerned about protecting their hives and preserving these precious pollinators.


Preventing and controlling Varroa infestations is essential for the health of bees and honey production. By monitoring hives carefully, using appropriate treatment methods, and promoting colony health, beekeepers can protect their hives from this harmful parasite.

In addition to the measures described above, it is important to stay informed about the latest research and recommendations on Varroa control. Beekeepers can find valuable resources from local beekeeping organizations, universities, and government agencies.

By working together, beekeepers can meet the challenge of Varroa and ensure the survival of these essential pollinators.
