Rats And Mice

Common Rat

The brown rat or common rat, is one of the best known and most common rats in the UK. This type of rat is either brown or grey, with a body up to 25cm long. Males typically weigh 350g and females 250g. The common rat has now spread to all continents, except Antarctica – making it the most successful mammal on the planet after humans!

Signs you have rats

  • Rat droppings – normally about 3-5mm long
  • Rat footprints and tail marks may be left in dust
  • Holes through walls, floors or burrows in outside areas
  • Rat teeth marks on food
  • Greasy smears left by fur rubbing against walls
  • Rat breeding rates

A rat’s lifespan is only around one year, but in that short time it can produce as many as seven rat litters, each of around 8-12 young!


The presence of mice in a building can be disasterous to both structure and reputation. Mice teeth grow throughout their lives so they need to gnaw continuiously to wear them down. Their instincts often cause damage to electrical cables, pipes and support structures.

Mice can also carry many diseases, such as tuberculosis, gastro-enteritis, salmonella, rat-bite fever, leptospirosis and many others. Their droppings contaminate kitchen surfaces and food stocks. Mice foul wherever they travel as they are incontinent.

Many insurance companies will no longer cover damage caused by mice.

Mice breed at an alarming rate!

It has been calculated that if two mice were left in a building with twelve months supply of food their population could grow to 2000!

Getting rid of Mice

The use of mice gels, contact dusts, traps and baits will control a mouse problem. However, unless used in conjunction with effective mouse proofing measures, a re-infestation will likely occur within weeks. Hawk Force can draw up a report on how best to mouse proof your property.
