NWRC Research Areas: Regulatory Support Services-Product Registration
The APHIS Wildlife Services (WS) NWRC Registration Unit is responsible for providing data and information to support regulatory approval of new or existing products needed by WS Operations. These products allow the WS Program to more efficiently address wildlife damage issues and protect agriculture, human health, and endangered species or critical habitats.
To meet this responsibility, the Registration Unit works closely with WS Operations, NWRC scientists, and APHIS headquarters staff to ensure that APHIS's products, regulatory studies, and other activities meet U.S. Environmental Protection Agency (EPA), U.S. Food and Drug Administration (FDA), and USDA Center for Veterinary Biologics (CVB) regulatory requirements. NWRC also works to develop new products for vertebrate wildlife with private companies, universities, and other agency collaborators.
APHIS currently holds federal pesticide registrations with the EPA for 12 active ingredients formulated into 24 end-use products for vertebrates. The end-use products meet the needs of bird management (two avicides), rodent management (12 rodenticides and two fumigants), predator management for livestock protection (two predacides and two fumigants), contraceptives for reproductive control (one for prairie dogs, one for white-tailed deer and one for feral and wild horses and burros), and a toxicant for managing brown treesnakes on Guam. These registrations include three anticoagulant rodenticide products and two acute toxicant rodenticide products registered for control or eradication of rodents on island. In addition, APHIS has developed recommendations for several minimum risk pesticide active ingredients that are exempt from EPA registration requirements: an egg oil treatment, snake repellents, and a wetting agent for blackbirds and starlings.

Bromethalin: Two end-use products containing bromethalin, an all-weather block and a place pack (containing pellets) are registered for eradicating and controlling rodents on islands for conservation purposes. These products are currently registered for use only on Wake Atoll, but may be used on additional islands under supplemental labels, if approved by EPA.

Zinc Phosphide on Wheat; EPA Reg. No. 56228-3
Zinc Phosphide Concentrate; EPA Reg. No. 56228-6
Zinc Phosphide on Oats; EPA Reg. No. 56228-14
Carbon and Sodium Nitrate (Gas Cartridge): Gas cartridges are incendiary devices designed to give off carbon monoxide when ignited. They are used to fumigate burrows of woodchucks, yellowbellied marmots, ground squirrels, and prairie dogs.
APHIS-Only Gas Cartridge; EPA Reg. No. 56228-2
Gas Cartridge; EPA Reg. No. 56228-61
AVICIDES
DRC-1339: DRC-1339 is a slow-acting avicide registered for controlling blackbirds, grackles, cowbirds, starlings, pigeons, collared doves, gulls, crows, magpies, and ravens that damage agricultural crops, personal property or prey upon protected species.
Compound DRC-1339 Concentrate - Livestock, Nest & Fodder Depredations; EPA Reg. No. 56228-29
Compound DRC-1339 Concentrate – Bird Control; EPA Reg. No. 56228-63
Corn Oil: Corn oil can be applied to eggs of pest birds during the nesting season to prevent hatching. Because nests are not destroyed and eggs are not removed, nesting birds are encouraged to continue incubation, often well beyond the normal time for hatching. This active ingredient is a minimum risk pesticide (MRP) exempt from EPA registration requirements, but still may require state registration.

Sodium Lauryl Sulfate: Sodium lauryl sulfate can be used as a wetting agent to control blackbirds and starlings in roosts. This active ingredient is a minimum risk pesticide and exempt from EPA registration requirements, but still may require state registration.
