In order to achieve its objectives, RRAC intends to actively participate in the field of rodenticide resistance, in particular to support studies to extend our understanding of the importance and distribution of rodenticide resistance, resistance management, resistance detection methods and the biochemistry of resistance mechanisms.
While resistance to some anticoagulant compounds exists in certain localities, particularly in the countries of North America and northern Europe and in the species Rattus norvegicus - Mus musculus/domesticusand Rattus rattus, (see Greaves, 1994, for a review), nowhere are resistant rodents impossible to control satisfactorily with currently available rodenticides. It is the opinion of RRAC that this will remain the case for the foreseeable future.
