Rats are a major hazard to health. They spread many forms of disease, especially through their droppings and urine.

Signs of Infestation

  • damage - caused by gnawing, holes, smears and droppings, packaging will often show tooth marks - the size of which will indicate whether it is a rat or a mouse
  • holes - made by the rats in doors and walls, and the entrances to nests, are about 80mm (three inches) in diameter, and nests may be made in wall and floor cavities
  • rat runs - having established the best route from one place to another, rats tend to use this route frequently. This run becomes soiled with the grease and other dirt on the rat's fur and will be very apparent in even moderate infestations
  • rat droppings - the amount of rat droppings present is a good indication of the size of the infestation and how long they have been there


Removal of food and water is important. The infestation should be controlled by using bait. This can be bought from hardware shops and garden centres. To be effective, baits must be readily available for the rat, but should not be accessible to other animals or humans, and extra care is needed if there are children in the house. The safety precautions and instructions given on the packaging must be adhered to. It is essential that all other food sources are removed in order to force the rats into eating the poison bait. Do not put food out for the birds.
