Abstract

Under an Environmental Protection Agency Experimental Use Permit, a pelleted bait containing 0.0025% (25 ppm) of the new anticoagulant difethialone was tested to determine the effectiveness in controlling Norway rats (Rattus norvegicus) and house mice (Mus musculus). Sixteen (16) individual field studies were conducted in five (5) geographical locations of the United States. The results were conclusive in showing that difethialone bait formulated at 25 ppm was both palatable and efficacious in controlling both Norway rats and house mice under actual field conditions.
