Laboratory evaluation of gophacide as a rodenticide for use against Rattus norvegicus and Mus musculus

Laboratory tests were carried out to assess the efficacy of gophacide as a rodenticide against the Norway rat (Rattus norvegicus) and the house mouse (Mus musculus). Results of feeding tests with wild animals suggest that the compound would be more useful against mice than rats, and that 0.3% would be a near optimal concentration for field trials for both species. The hazards of using gophacide as a rodenticide are discussed.
