Rats and mice (rodents) can be a pest on both private and public property.
Land owners are responsible for managing rodent problems on their private land.
Council manages pest programs on public land. Our programs focus on animals that are identified as priority pests, in line with our Regional Biosecurity Plan(PDF, 13MB).
Introduced or Native Rodents?
It is important to note that not all rats and mice are considered pests, with several native species present in Australia, including the Water Mouse, Bush Rat and Water Rat.
You don't need to control native rats and mice; however, introduced species should be controlled immediately. Under the Biosecurity Act 2014, everyone has an obligation to prevent or minimise the impact of invasive animals on human health, social amenities, the economy and the environment. For more information about controlling invasive animals, visit the Queensland Government website.
The more commonly known rat and mouse species introduced to Australia are the Norway Rat (Rattus norvegicus), the Roof Rat (Rattus rattus) and the House Mouse (Mus musculus). These animals are well adapted to living in very close association with humans, sharing their food, water and shelter.
The Norway Rat (Brown or Sewer Rat) usually lives in burrows beneath buildings, and can be found in sewers and around rubbish dumps. This rat prefers to eat plant, animal and meat material, and usually remains close to their nest when scavenging for food. It is the most common and destructive introduced rat species in Australia.
The Roof Rat (Black Rat) is an excellent climber and jumper. It nests in the upper parts of dwellings such as rooftops, walls and furniture. This rat prefers to eat fruits, nuts, grains and vegetables. It tends to roam to find food, but usually returns to its existing nest.
The House Mouse will live anywhere with shelter, warmth, food and nesting materials, including areas in and around houses, buildings and structures. It prefers to eat cereal grains and does not roam far in search of food.
Discouraging rodents
The following practices can help reduce and prevent rodent infestations on your property.
- Make sure rubbish bins have tight-fitting lids and are emptied regularly
- Keep your home and property clear of rubbish
- Keep stacked materials such as wood and bricks at least 30cm above the ground to minimise spaces for rats and mice to hide, nest in or pass through
- Regularly clean out sheds, storage areas and get rid of unwanted items
- Remove unwanted undergrowth – cut back grass, bushes, and creepers which may provide cover or access to the roof
- Remove fallen fruit, seed, waste and pet faeces from aviaries and chicken pens
- Dispose of food scraps promptly and clean food preparation areas thoroughly
- Do not use open compost heaps
- Do not compost any animal products (fish, meat, chicken, cheese, butter) or pet faeces
- Inspect living and working areas for potential rodent entrances and block them where possible with concrete, hard setting filler, steel wool or heavy gauge sheet metal
- Block access points to cupboards containing food and food-preparation utensils
- Leave out only enough pet food for pets to eat soon after it is placed there
- Store poultry food in vermin-proof containers with close-fitting lids
- Cover rainwater tank openings and floor vents with wire mesh no coarser than 1mm, and check and maintain these regularly.
How do I control rats and mice on my property?
If you have determined the presence of rats and/or mice at your property, you should contact a licensed Pest Management Technician for advice and treatment.
Alternatively, you can purchase bait or traps from a hardware, produce or supermarket store. You must comply with the directions on the product label at all times and only use the product for its intended purpose. Council does not supply rat bait or traps to residents.
Before using poison, you might want to consider these points:
- If rodents die and decay in hard-to-reach places, they may cause an offensive smell
- There is a risk that pets and children could eat toxic baits or poisoned rodent bodies
- Some people are sensitive to rodent control chemicals in their environment.
Ensure that you dispose of any rodents safely. If placing them in your rubbish bin, double-bag and ensure the lid is securely shut.
Once your property is free from rodents, you should ensure the above control measures are implemented to reduce the likelihood of a re-infestation.
Reporting rodent problems
Council does not directly manage rodent issues on private property.
If you believe the state of a neighbour’s property may be contributing to rats/mice on your property, raise the alleged issue directly with the person responsible and give them a reasonable timeframe to resolve it. If the matter cannot be resolved, contact Council with details of the cause and location, and the time and date of any observed rodent sightings. Council will then investigate the issue with the property owner.
To make a report, please contact Council on 07 4742 4100 or council@cloncurry.qld.gov.au.
