Survey set to tackle ‘super rat’ issue

31 Jul 2020

A survey has been launched to establish the extent to which resistant ‘super rats’ are breeding in the UK. And it should also help producers to better control rodent infestations.

Research published by the University of Reading's Vertebrate Pests Unit suggests that resistance is spreading, due to the use of anticoagulants containing the actives bromadiolone and difenacoum.

Resistant rodents

Products that are ineffective on resistant rodents will only kill rodents that have no resistance. And this then leaves resistant rodents to breed, which is causing numbers to increase rapidly.

The survey, which is supported by BASF, will raise awareness of resistance and compile fresh data about the use of rodenticides on farms throughout the UK.

Online survey

The survey is available to complete online until September 30, 2020, and aims to establish: how often producers are using rodenticides; which products are being used; and which regions of the UK are reporting the most problems with resistance.

“The information gathered will help to reduce the use of products that rodents have become resistant to and minimise the threat to non-target species,” adds the Campaign for Responsible Rodenticide Use’s Alan Buckle.
