An alert by the Campaign for Responsible Rodenticide Use (CRRU) has been issued to remind farm 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.
A service company was found to be using a product specifically to control wood mice on the grounds that the label had said ‘for the control of rats and mice’, giving no specification over common or scientific names of target species. The company in question had taken this to mean the product could be used against wood mice, however immediately its use against wood mice after the error was identified.
CRRU has said that marketing statements saying a product may be used ‘against mice’ does not imply permission to use it against wood mice.
CRRU has also reminded all authorisation holders that target species should clearly show which species are being targeted prominently on the outer package of all UK professional rodenticide products in addition to a statement on leaflets inside the pack.
