We are receiving unusually high rates of calls from clients regarding rats and mice, (rodents), in Brisbane’s western suburbs. The top suburbs of the list for rodent control at the moment are St Lucia, Indooroopilly and Auchenflower.
We recently conducted a rodent pest control job in Auchenflower, where our sleep deprived customer had discovered that a rodent had entered the roof cavity, making scratching noises well into the early hours of the morning.
Rodents are normally considered a winter pest; however this year due to wet weather conditions and cooler than normal temperatures, I have noticed a spike in rodent activity and calls.
Rodents eat practically anything humans eat, they get plenty of food from home gardens, fruit or nut trees and even parts of some ornamental shrubs and flowers. Garbage disposals also attract rats into household and street sewer lines. Rats and mice have long been a problem in domestic environments where food is plentiful and convenient nesting sites are both numerous and hard to eliminate.
Major problems caused by rats and mice
- They eat food and contaminate it with urine and excrement.
- They gnaw into materials such as paper, books, wood or upholstery which they use as nest material. They also gnaw plastic, soft metals such as lead and aluminum, and wiring which may cause a fire hazard. Rodents will continually gnaw for food and Harborage.
- Rodents, or the parasites they carry, (such as fleas, mites and worms) spread many diseases.
- Asthma is one of the most common diseases in the home caused by Rodent droppings.
- Rats can damage ornamental plants by burrowing among the roots, or feeding on new growth. They also eat some garden vegetables.
- Rats and mice are socially unacceptable.
- A female Rodent can have between 84 to 120 young in her life span.

How to treat rodent problems
When all else fails and pest control measures need to be implemented, Amalgamated Pest Control technicians will look at all the available options. The two most effective methods of control of rats and mice are:
- Rodent Trapping: Using traps to physically trap and remove rodents.
- Chemical Control: Includes a wide range of baiting techniques, most commonly bait blocks used in Tamper Resistant Rodent Stations. These baits are secured inside the station and cannot be removed, making them pet and child friendly. Where needed, tracking powders, gels and other baits may be used as required.
How to avoid rodent infestations
- Ensure all of your household garbage is in tightly sealed in bins, which rodents cannot access – restrict their access to food as much as possible.
- Alter your building so that rodents cannot gain entry. Look for access holes that rodents can use such as where pipes enter buildings and gaps under external doors. Sealing these points and others similar will make it harder for rodents to enter. Using a gutter guard to seal the roof can be also be helpful in stopping them entering the roof via the gutters. Restrict their access to shelter as much as possible.
- Trim excess trees and shrubs from around the perimeter of the structure, especially trees that overhang the roof. This will take away both harbourage areas and make accessing the roof a little bit harder for them.
We advise our customers to make these changes to their home and consider the installation of a gutter guard solution.
