Identifying common brown rats
The common brown rat typically measures 20cm to 27cm in length and weighs between 100g and 500g. They usually have a brownish-grey back and grey underside, although colours can vary. Rats have continuously growing incisor teeth, which is why they gnaw constantly, causing damage.
Understanding rat behaviour
Rats usually stay within 50m of their home but can range up to 300m. They often relocate every 2 weeks, depending on food sources and can travel several kilometres in search of food. Rats are nocturnal and are commonly found in fields, gardens, and sewers. They reach sexual maturity at 3 to 4 months old and can produce 6 to 11 young per litter.
Preventing rat infestations
To reduce the risk of rats in your area:
- use wire mesh (1 cm x 1 cm) under compost bins or place them on a concrete base
- trim overhanging branches near roofs to prevent access to lofts
- keep long grass to a minimum to reduce places for them to live
- store rubbish in sealed bins with fitting tops
- ensure good drainage and repair any broken drains or inspection chambers
- inspect and repair any holes or faults in house and shed brickwork
- avoid scattering bird food in gardens; use feed containers instead

Distinguishing between rats and mice
Rats and mice are different species with unique characteristics. The most common types found in homes are the common rat (also known as the Norway rat, Brown rat, or Sewer rat) and the House mouse. It's important to identify which you have, as treatments and preventive measures differ.
