EPA is committed to helping beekeepers combat Varroa mites. Varroa mites are parasites that feed on developing bees, leading to brood mortality and reduced lifespan of worker bees. They also transmit numerous honeybee viruses. The health of a colony can be critically damaged by an infestation of Varroa mites. Once infested, if left untreated, the colony will likely die. By expediting the approval of pesticides that target Varroa mites and publishing information about the products, EPA is helping beekeepers deal with these challenging pests.

The pesticide products listed on this page are registered by EPA at the federal level for use against Varroa mites. Rotating products to combat Varroa mites is an important tactic to prevent resistance development and to maintain the usefulness of individual pesticides. Beekeepers are encouraged to check with their state pesticide regulatory agencies to determine the regulatory status of the products in the individual states.

Primary registered products in the list have 2-part EPA registration numbers and are listed in bold. Distributor products have a 3-part EPA registration number, with the first two numbers reflecting the primary registered product’s registration number. Distributors may market their products under different names, but the formulations and uses are identical to the primary registered.
