A new project is attempting to map resistance to anticoagulant rodenticides across the UK and other European countries and your help is needed.
The Rodenticide Resistance Action Committee (RRAC) is working with the University of Reading to genetically screen local populations of Norway rat and house mouse to identify those with resistance.
The resulting data is then used to inform an interactive mapping tool that can tell the user what type of resistance is present in their area and which anticoagulants are best to use against the rodents.
However, more data is needed to fill gaps in the mapping and ensure the information provided is up-to-date.
You can help the project by submitting a tail cutting from a rat or mouse in your area, which will then be screened for any resistance mutations.

Resistance to both first- and second-generation anticoagulant rodenticides developed soon after their introduction and has been spreading ever since. Using the most appropriate product in your location will help preserve the lifespan of these important tools while limiting the risk posed to non-target animals.
