EPA Rodenticide Risk Mitigation Decision (RRMD)
On June 4, 2011, new regulations on rodent bait products went into effect, mandated by the U.S. Environmental Protection Agency (EPA) under the Rodenticide Risk Mitigation Decision. These regulations significantly impact the sale and use of rodenticides by both professional pest control operators and the general public. For retail sales, the use of second-generation (single-feeding) anticoagulants has been restricted—these products will no longer be available to consumers. However, professional applicators will continue to have access to all active ingredients. For retail users, rodenticides must now be sold only in the form of solid blocks or soft baits, and packaging must not exceed one pound.
Professional applicators face new packaging requirements as well: first-generation anticoagulants must be sold in a minimum package size of 4 lbs, and second-generation products in packages of at least 16 lbs. Additionally, when used outdoors above ground, rodent baits must be placed in tamper-resistant bait stations and generally must be located within 50 feet of a building or structure. These new rules aim to reduce accidental exposure to children, pets, and non-target wildlife, while still allowing effective rodent control through regulated professional use. Existing product inventory already in distribution or possession of end users can continue to be sold and used as currently labeled, avoiding immediate waste of pre-regulation stock.
