Pest control best practise for years has meant that permanent baiting with poison should not happen. Unless risk assessments show it is needed, reviewed regularly. Permanent baiting increases the risk to non-target animals. Poison should only be used when there is a valid reason, rodent activity, and in a very controlled and planned way, with regular checks (at least monthly). Going back to non-toxic control once the activity or high risk has stopped. If you need a survey or help in Essex, London or Kent - call MG Pest Control.
