Rodenticide alert prompts reminder of permitted target species

The Campaign for Responsible Rodenticide Use (CRRU) has reminded users of rodenticides covered by the UK stewardship regime that no product is authorised for control of wood mice (Apodemus sylvaticus), also known as long-tailed field mice.

Long -tailed Field Mouse

This reminder follows an alert to the CRRU complaints procedure. On grounds that a label had said ‘for the control of rats and mice’, a service company was found to be using a product specifically to control wood mice. 

The product label in question carried neither common nor scientific names of target species. The service company had taken this to mean the product could be used against wood mice, which it halted immediately the error was identified. 

As a result, CRRU has also reminded all authorisation holders that target species, for 

example Norway rat (Rattus norvegicus), Black rat (Rattus rattus) or house mouse (Mus

musculus), should be shown prominently on the outer package of all UK professional rodenticide products. in addition to a statement on leaflets inside the pack. 

CRRU chairman Dr Alan Buckle said: “For the avoidance of doubt, marketing statements saying a product may be used ‘against mice’ does not imply permission to use it against wood mice.”
