What should I do if I get problems with rats?

Rats are suspicious, and therefore may be more difficult to control than mice. If you suspect that you have a problem with rats, please contact a professional pest control company through your "householder's comprehensive insurance" or contact the property owner.

A trained professional with a special permit from the National Board of Health and Welfare may use chemical pesticides in authorisation class 1 So (Read more about authorisation classes). They have knowledge of safe and efficacious chemical pest control such as rat poison and they also know about alternative methods.
