Introduction. Thank you for taking time to complete this short survey, which will take less than ten minutes to complete. These results will help us understand how rodenticides are used on farms across the UK and identify areas of rodenticide resistance, comparing this information to the results gathered in our 2020 rodent survey. As a thank you for taking part in this survey, the first 200 responses will receive a free Selontra® beanie hat. Please note, this survey is for completion by only those within the UK. A report detailing the results will be released in summer 2022.
