Conditions under which permanent baiting with rodenticide is allowed have been updated by the Campaign for Responsible Rodenticide Use UK to cover a critical difference between outdoor and indoor locations.
In both situations, CRRU chairman Dr Alan Buckle emphasises that the fundamental requirement remains for a professional rodenticide user responsible for the site to identify and document ‘a high potential for reinvasion where other methods have proved insufficient‘.
The updated ruling applies to indoor locations only, where permanent baiting is usually more likely against reinfestation by mice than rats. It specifies that the frequency of routine inspections and re-visits when target pest presence is indicated are a matter for the pest control technician in charge of the control programme.
Dr Buckle says this update comes about in response to feedback from professional pest controllers at a British Pest Control Association (BPCA) forum.
Unchanged is that permanent outdoor bait points loaded with rodenticide continue to require re-inspection at least every four weeks. Permanent baiting in any location is permitted only using products with labels stating specifically such use.
