The US EPA has posted a list of pesticides registered for use against Varroa mites to help beekeepers identify products that can help fight this invasive species of bee pest. As part of EPA’s role in the National Pollinator Health Strategy, the Agency has expedited its review of registration applications for new products targeting pests harmful to pollinators.
In 2015, EPA expedited the review of applications for oxalic acid and a new biochemical miticide, potassium salts of hops beta acids, to provide more options for beekeepers to combat Varroa mites. More pest control options help avoid the development of resistance toward other products.
As part of the National Pollinator Health Strategy, EPA 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 honoring another commitment in the National Strategy.
The pesticide products listed 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.
