Special warnings
Special warnings for each target species:

The effectiveness of the product is significantly reduced in the presence of brood. Use of the product should be restricted to colonies with little or no brood. Therefore, treatment is best done in winter or when queens are isolated. In the case of summer treatment in families with isolated mothers, the greatest efficacy is achieved when the isolation period lasts at least 25 days and there is no brood left in the colonies. Sufficient effectiveness can be obtained in the case of a small to medium infestation with Varroa destructor. Heavily infested colonies can die from Varroa destructor mite infestations, despite proper use of the product. It is recommended to use the product as part of an integrated varroa control program and to regularly monitor mite infestation.

Special precautions for use in animals:

Do not exceed the recommended dose. Repeating the treatment may strongly stimulate the colony. All families in the same apiary should be treated simultaneously to avoid reinfestation. The hives should not be disturbed for a few days after treatment. During treatment, care should be taken to ensure that product residues do not settle on the frames that will still be used for honey production in that season.
Special precautions for the disposal of unused veterinary medicinal products or waste materials:
Any unused veterinary medicinal product or its waste should be disposed of in accordance with applicable regulations. Api-Bioxal should not enter water courses as this may be dangerous for fish and other aquatic organisms.
