Risk mitigation measures for anticoagulant rodenticides
Anticoagulant rodenticides, i.e. rodenticides preventing blood coagulation, are a health and environmental hazard. Rodenticides should only be used, if absolutely necessary, and instructions for use should be followed.
Mice and rat control is important to prevent them from spreading diseases and destroying structures in buildings.
EU countries authorise anticoagulant rodenticides for rodent control for a period of 5 years at a time. Rodents may become resistant to rodenticides and it is therefore important to follow the instructions for use. Pest control operators should report to The Finnish Safety and Chemicals Agency (Tukes), if rodents are not depopulated despite pest control measures taken.
Limitations for the use of anticoagulant rodenticides
All active substances in rodenticides with anticoagulation activity have been categorised as toxic for reproduction category 1A or 1B. This classification applies to all products with active substance concentration of 0.003% or more.
Products categorised as toxic for reproduction are not approved for consumer use.
European Chemicals Agency (ECHA) proposes in their statements approved by the Biocidal Products Committee the following measures to mitigate risks from the use of rodenticides:
- Detailed recommendations for the approval of the products
- User group-specific conditions also listed in the implementation regulations for the active substances, Official Journal of the European Union. Risk mitigation measures are implemented to prevent exposure of humans and other animals to rodenticides.

|2||Approval for use by consumers can only be granted for products for indoor mice control.|
|3||Approval for use by consumers can only be granted for pre-baited mice bait stations.|
|4||Efficacy of products for mice control should be tested in yellow-necked mice, Apodemus flavicollis. Testing of efficacy is also recommended in bank vole, Myodes glareolus. Products for professional use in mice control are for outdoor use only, i.e. near buildings, provided that their efficacy in yellow-necked mice has been shown. Yellow-necked mouse is more common in Finland than house mouse, Mus musculus.|
