When rodenticides are used outdoors, birds of prey and pets are exposed to a high risk of secondary toxicity. Moreover, rodenticides based on anticoagulants are substances with a high risk of persistence, bioaccumulation and toxicity (PBT substances) and are environmentally hazardous. This is why the Ctgb restricts the use of these substances.
For all authorisations that previously included outdoor use, this use has now been prohibited by the Ctgb.
Under specific conditions, outdoor use as part of Integrated Pest Management (IPM) and with certification of the users is still possible.
