Rats and mice are notorious disease carriers. They will contaminate your food and home with their faeces and urine.

They are incontinent and leave urine trails as they roam and are able to chew through wires, get into food areas and pose safety and health risks with spread of diseases if left untreated.

Buildings are ideal for rats and mice because they provide food, water, warmth and shelter. For these reasons you may notice rats and mice inside buildings more in the cooler months.

Rats carry diseases and can cause structural damage to buildings by burrowing and gnawing. They undermine building foundations and slabs. Rats also may gnaw on electrical wires or water pipes, either in structures or below ground. They damage structures further by gnawing openings through doors, window sills, walls, ceilings, and floors. Considerable damage to insulated structures can occur as a result of rat burrowing and nesting in walls and attics. There are 2 main varieties of rats in Australia:

Three main rats and mice pest species in Australia


House MouseHouse Mouse
The house mouse has a body 60 mm – 100 mm. They have a pointed snout, small rounded ears, and a long naked or almost hairless tail.  Mice can be found around homes, buildings that have poor hygiene standards, garage, kitchen areas, where they have places to hide and food sources. They are more likely to seek shelter in houses and structures during the cooler seasons.  Mice droppings have even been implicated as potential asthma triggers in children.
