Rats & Mice

Rats and Mice can transmit many diseases, contaminate food, they are also capable of gnawing through electrical wiring causing expensive and costly repairs we can’t afford.

They have been known to cause fires, which most insurance companies will not cover under some policies.









There are two types of rats, The Norway Rat and the Roof Rat. And only one type of mouse, The House Mouse. The Norway rat is the larger of the two rats and has the thicker body, blunt snout, small close-set ears and a tail shorter than it’s body length. The Roof Rat is smaller of the two rats and is of slighter build. It has a more pointed snout, large prominent ears and a tail longer than it’s body length. The House Mouse is small and has rather large ears, a pointed snout and a tail at least as long as it’s body.

Life Cycle

  • The Norway rat normally lives for 9-12 months and may have 5-6 litters per year each time with 8-10 young. The young achieve sexual maturity at 3-4 months. Clearly, it’s reproductive potential is very high.

The Roof Rat also lives for 9-12 months and may have 4-5 litters per year each with 6-8 young. The young achieve sexual maturity at 3-4 months. It’s reproductive potential is also very high.

The House Mouse tends to live for 12 months and may have 6-10 litters per year, each with 5-6 young. The young achieve sexual maturity sat about 6 weeks. Their reproductive potential is extremely high.


  • The distribution and abundance of pest rodents are largely determined by the availability of food and shelter. Rats and Mice may live and nest within buildings indefinitely, provided they have access to food, water and shelter. Often rats rodents will enter buildings only seasonally. In such cases, the rodents may begin to investigate buildings in autumn and winter, if a suitable nesting site is established with a food source within reasonable range, the somewhat warmer nesting conditions may facilitate more productive breeding.


Historically, the role that rats and mice have played in the transmission of diseases to humans has been of profound importance. The Black Death (bubonic plague), which claimed more than 25 million lives in the fourteenth century Europe, is perhaps the most documented case history of rats and disease.
