Species Notes for this Location: Rattus norvegicus thrives in and around farm buildings in the United Kingdom. R. norvegicus has outcompeted the earlier arrival of Rattus rattus in the British Isles (Appleton et al., 2002).
Management Notes for this Location: The main management tools for controlling Rattus norvegicus populations in the UK are rodenticide baits. Surveys of farm rat populations have revealed widespread resistance to warfarin, and by inference other first-generation anticoagulants. Reports of resistance to second-generation anticoagulants arose shortly after their introduction in the 1970s.
Impacts: Disease transmission: Rattus norvegicus present a zoonotic disease risk in the UK. Human nuisance: Rattus norvegicus causes damage to stored food and structures in the UK.
