Understanding the Problem

Before delving into the different pest control strategies, it is essential to understand the nature of the problem. Rodents, including more than 2,200 species worldwide, have successfully populated every continent except Antarctica due to their small size, rapid breeding cycle, and ability to consume a variety of foods. Australia alone is home to over 60 native rodent species, along with three introduced pest species.

Rodents can cause extensive damage to residential households, commercial businesses, farms, and livestock. Their gnawing behavior can destroy materials, while their excretions can contaminate food supplies. However, it is important to note that not all rodents are considered pests. Many rodents play crucial roles in the ecosystem by spreading seeds and spores and serving as prey for meat-eating animals.

Identifying Common Rodent Pests

To effectively combat rodent infestations, it is important to be able to identify the common pest species. The three primary rodents that cause problems in human settlements are the Norway rat (Rattus norvegicus), the roof rat (Rattus rattus), and the house mouse (Mus domesticus).

Norway Rat

The Norway rat, also known as the common rat, sewer rat, or brown rat, is the larger of the two pest rats. It typically has a lifespan of 9 to 12 months and can reproduce rapidly. Norway rats are omnivores and will eat a variety of foods, including cereals, meat, fish, vegetables, and fruits. They are characterized by their brown or gray fur, blunt nose, short thick ears, and a body length of 20-27 cm.

Roof Rat

The roof rat, also known as the ship rat or black rat, is smaller than the Norway rat and has a lifespan of about 9-12 months. Roof rats are excellent climbers and are commonly found in built-up areas or near the coast. They primarily feed on cereals, grains, fruits, and insects. Roof rats have gray, black or brown fur, a slender body, pointed nose, and large ears.

House Mouse

The house mouse is small in size, with a lifespan of approximately 12 months. Female house mice can produce 6-10 litters per year, making them highly prolific breeders. They have a varied diet, including fruits, nuts, grains, and animal feed. House mice are characterized by their brown or gray fur, small slender build, pointed nose, and large hairy ears.

Signs of Rodent Infestation

Identifying the signs of a rodent infestation is crucial for prompt pest control action. By being vigilant, you can take necessary measures to eliminate rodents before they cause extensive damage. Here are some common signs of rodent infestation:

  1. Visual sightings of rodents scurrying across floors or climbing on walls.
  2. Droppings found in kitchen cabinets, drawers, or along rodent pathways.
  3. Sounds of gnawing, scuffling, or squeaking coming from hidden areas.
  4. Urine stains resembling sprinkles on surfaces, especially along rodent paths.
  5. Greasy marks along walls, indicating rodent travel routes.
  6. Burrow holes around buildings, particularly near potential entry points.
  7. Physical damage caused by gnawing on wires, furniture, and food containers.
  8. Missing or partially eaten food, especially grains or fruits.
  9. Unusually excitable pets that may be indicating the presence of rodents.

DIY Pest Control Methods for Mice and Rats

If you are dealing with a small rodent infestation, there are several DIY methods you can try to eliminate the problem without the need for professional intervention. These methods can be effective for small-scale infestations and require consistent implementation. Here are some useful tips for getting rid of mice and rats:

Set Traps

Traps are effective tools for capturing mice and rats alive. Place traps strategically in areas where rodents are frequently seen, such as along their travel routes or near food sources. Use a variety of traps, including glue traps, snap traps, or live capture traps, and bait them with enticing treats like peanuts or cheese. Check the traps regularly and release captured rodents far from your property.

Seal Off Openings and Tiny Holes

Rodents can enter your home through small openings and gaps. Inspect your property for any potential entry points, such as cracks in walls, windows, and doors. Seal these openings using materials like aluminium foil or duct tape to prevent rodents from entering.

Get a Cat

Cats are natural predators of rodents and can be an effective deterrent. If no one in your household or frequent visitors are allergic to them, consider getting a cat. The presence of a cat alone can help keep mice and rats away from your home. However, not all cats are created equal in the hunter stakes.  You may end up with mice AND another mouth to feed!

Use Essential Oils as Repellents

The strong smell of essential oils, such as clove oil and peppermint oil, can act as natural repellents for mice and rats. Soak cotton balls with these oils and place them in areas frequented by rodents, such as cupboards, drawers, and near entry points. While not 100% effective, this method can help deter rodents from infesting your home.

When to Seek Professional Pest Control Services

While DIY methods can be effective for small infestations, severe rodent problems or persistent infestations may require the assistance of professional pest control services. Pest control companies have the expertise, experience, and access to specialized chemicals and techniques to tackle even the most challenging rodent infestations. Here’s what you can expect when hiring a professional mice exterminator:

  1. Inspection and Assessment: The exterminator will visit your home to assess the extent of the infestation and identify the specific rodent species causing the problem.
  1. Extermination Plan: Based on the assessment, the exterminator will develop a customized extermination plan tailored to your specific infestation problem.
  1. Quotation and Explanation: You will receive a price quotation for the services, along with a detailed explanation of the techniques and methods the exterminator will employ. They will also provide an estimated timeline for the extermination process.
  1. Preparing Your Home: The exterminator will provide instructions on how to prepare your home for the extermination process, ensuring the safety of your family and pets.

Professional Pest Control Methods for Rodent Extermination

Professional mice exterminators employ a range of effective techniques to eliminate rodent infestations. These methods are tailored to different species of mice, the severity of infestations, and the specific conditions of each property. Here are some common methods used by professional exterminators:

The first step in professional rodent control is identifying and sealing off entry points. Exterminators thoroughly inspect the interior and exterior of your home to locate potential entry points, such as cracks, holes, or gaps. These entry points are then sealed using materials like sheet metal, wire mesh, or hardware cloth to prevent rodent access.

Exterminators strategically place traps in key areas of infestation. Various types of traps, including glue traps, snap traps, or live capture traps, may be used depending on the situation. Traps are baited with rodent attractants and regularly checked to remove captured rodents.

Bait stations are designed to lure rodents with poisoned treats, leading to their eventual demise. Exterminators place bait stations in areas frequented by rodents, ensuring the safety of humans and pets. Dead rodents are promptly removed to prevent odor and hygiene issues.

Fumigation is a last resort method used when other techniques fail to eliminate rodent infestations. This method involves treating the entire premises with fumigants to eradicate rodents. It is a highly controlled process that requires residents to vacate the property temporarily due to the use of potent chemicals.

Before fumigation, it is important to make necessary preparations, such as finding alternative accommodation, notifying gas suppliers to cut off the supply, and sealing food and consumables in airtight storage units. Gas company coordination and following safety protocols are crucial during this process.

Safety Precautions and Regulations

When dealing with pests, it is important to prioritize safety and follow regulations to prevent any harm to humans, pets, and the environment. Here are some safety precautions and regulations to keep in mind:

  1. Read Product Labels: Always read and follow the instructions on pest control products, including safety information and usage guidelines.
  1. Personal Protective Equipment (PPE): Always read and follow the instructions on pest control products, including safety information and usage guidelines.
  1. Secure Bait Stations: Place bait stations in locations inaccessible to children, pets, wildlife, or livestock. Use lockable bait stations to prevent accidental exposure.
  1. Regular Inspection: Inspect bait stations regularly and remove baits if the rodent problem ceases. Dispose of baits properly.
  1. Educate Occupants: Notify all occupants of the building about the use of pesticides and ensure they are aware of safety precautions
  1. Prevent Contamination: Do not place baits or tracking powder in areas that can contaminate food or food-handling areas.
  1. Store pesticides in their original containers with intact labels, avoiding transfers to alternative containers.


Rodents, such as mice and rats, can pose significant health risks and cause extensive damage to properties. It is crucial to implement effective pest control methods to eliminate these pests and create a safe living environment. Whether you choose to tackle the problem yourself or seek professional assistance, understanding the nature of the infestation and employing appropriate techniques will help ensure successful rodent eradication.
