Wondering how to keep rats and mice away from your property for good?
Rodents are more than just an inconvenience—they can carry diseases, cause property damage, and contaminate food sources. In Perth’s warm climate, homes and businesses are particularly vulnerable to rodent infestations, especially during cooler months when pests seek shelter indoors.
Whether you’ve already seen signs of activity or want to prevent an issue before it starts, understanding the most effective rodent control methods is essential. In this blog, we’ll explore how to detect a problem, stop entry, and deal with rodents in a safe and sustainable way.

Identifying a Rodent Problem: Early Signs to Watch For
How to Spot the Warning Signs of Infestation
Rats and mice are nocturnal, elusive, and fast breeders—which means they can quickly overrun a property before you’re even aware of their presence. Knowing the early warning signs can help you take swift action before the issue becomes a full-scale infestation.
Key signs to watch for include:
- Droppings: Small, dark pellets found in cupboards, behind appliances, or near food storage.
- Gnaw marks: Rodents will chew through plastic, wood, and even electrical wiring.
- Scratching noises: Especially at night, from roof cavities, walls, or under floors.
- Grease marks: Oily trails left by their fur as they move through tight spaces.
- Nesting material: Shredded paper, fabric, or insulation used for building nests.
Risk Areas in Perth Homes and Businesses
In Perth, rodents are commonly found in roof voids, garages, commercial kitchens, and warehouse spaces. The city’s mix of suburban housing and industrial sites gives rodents plenty of access to food, water, and shelter.
Infestations can affect both health and reputation, especially in hospitality and food-handling businesses. For fast and thorough removal, it’s best to speak with a team offering an expert rodent control service in Perth that knows the local environment and pest behaviour.
Common Entry Points in Perth Properties
Rodents are incredibly resourceful when it comes to accessing your property. In Perth homes, common entry points include broken roof tiles, gaps under external doors, unsealed vents, and wall cavities. Older properties are especially at risk due to shifting foundations and wear over time. Air conditioning ducts and plumbing access points are also often overlooked, creating easy tunnels for mice and rats.
Regularly inspecting these vulnerable spots—especially after strong winds or storms—can help you catch potential issues early. Sealing these access points with rodent-proof materials not only blocks entry but also deters further investigation by foraging rodents.
Seasonal Rodent Behaviour in WA
Rodents in Perth tend to be more active indoors during the cooler months of the year. As temperatures drop, they look for warm, dry shelter close to food and water—often making homes and commercial buildings their primary targets. In warmer months, activity might shift outdoors but remains prevalent in shaded or cluttered areas.
Being aware of these seasonal patterns helps you prepare your property in advance. Scheduling professional inspections just before autumn can help prevent infestations before they start.

Rodent-Proofing Your Property: Prevention is Key
Simple Structural Fixes to Keep Rodents Out
The most effective form of rodent control is stopping them from getting inside in the first place. Rats and mice can squeeze through holes as small as a 20-cent coin, so sealing every potential entry point is critical. Focus on:
- Gaps around pipes, vents, and cables\
- Cracks in exterior walls or foundations
- Broken or missing weather seals around doors and windows
- Damaged roof tiles or eaves
Use steel wool, wire mesh, or expanding foam to fill gaps. Avoid materials rodents can chew through.
Sanitation and Storage Practices That Deter Rodents
Rodents are attracted to food and water sources. Good sanitation and storage practices reduce this appeal:
- Store food (including pet food) in sealed containers.
- Empty bins regularly and keep lids tightly closed.
- Clean up crumbs, spills, and grease in kitchens and food areas.
- Avoid stacking boxes and clutter in storage areas—they make ideal nesting sites.
Even outdoor areas can be a risk. Compost bins, fruit trees, and chicken coops should be monitored closely. Whether you’re a homeowner or business operator, rodent-proofing is an essential first step before contacting an expert rat control service for more targeted treatment.
Landscaping Tips to Deter Rodents
Your garden can be an unsuspecting haven for rodents if not properly maintained. Overgrown vegetation, thick hedges near the home, and leaf litter create perfect hiding and nesting spots. Try to maintain a clear zone of at least half a metre between your home’s external walls and any garden beds or dense plantings.
Compost bins should be rodent-proof with sealed lids, and fruit trees should be regularly cleared of fallen produce. Avoid using wood mulch directly against your home’s foundation, as it retains moisture and offers ideal cover for rodents.
Commercial Property Considerations
Businesses, especially those in the food or retail sectors, need to take additional precautions. Large stockrooms, ceiling cavities, and waste disposal areas often provide secluded nesting spots. Food prep zones should have strict hygiene protocols, and staff should be trained to identify and report early signs of rodent activity.
Implementing a formal pest management plan is essential. Regular inspections, bait stations, and compliance with WA health regulations are all part of keeping commercial spaces rodent-free and reputation-safe.

Safe and Effective Control Options for Rats and Mice
Understanding the Tools: Baits, Traps, and Repellents
There’s no one-size-fits-all approach to rodent control. Depending on the severity and location of the problem, a combination of traps, bait stations, and exclusion techniques may be required.
- Bait stations: Secure, tamper-resistant units placed strategically around the property. These use anticoagulant baits to eliminate rodents discreetly.
- Snap traps: Effective for small-scale problems and useful for monitoring activity.
- Live traps: More humane, but require frequent checking and appropriate relocation methods.
- Ultrasonic repellents: These devices claim to deter rodents with high-frequency sound but often offer mixed results.
Mice vs Rats: Tailoring Your Approach
Mice behave differently to rats. They tend to stay closer to their nest and require less water. Their entry points are also smaller and harder to find. That’s why mice pest control often requires more frequent inspections and finer detection techniques.
In both cases, DIY efforts can help temporarily, but for long-term relief, engaging rat pest control professionals who understand Perth’s specific pest patterns is often the best route.
How to Choose the Right Trapping Method
When selecting traps, it’s important to consider the size of the infestation and the layout of the property. For isolated issues, snap traps are effective and low-cost. However, they require daily checking and careful placement in areas of known activity. For larger properties or harder-to-access spaces like roof voids, bait stations offer a more efficient long-term solution.
Professionals often deploy a mix of methods—traps for quick knockdowns and baits for hidden or hard-to-reach colonies. Placement strategy is just as important as the tools themselves.
Environmental and Ethical Considerations
Humane control is a growing concern for many Perth property owners. Live traps allow for catch-and-release but come with their own challenges, including legal restrictions on relocation. Additionally, certain types of poison can harm non-target species such as birds or pets if mishandled.
Using eco-friendly baits and tamper-proof stations reduces environmental impact and improves safety. This is another reason why partnering with licensed professionals ensures not only results but peace of mind.
Why Professional Help Makes All the Difference
Experience, Safety, and Long-Term Results
While DIY methods may offer short-term fixes, professional pest technicians bring experience, certified products, and thorough inspections to the table. They can assess not just where rodents are now, but how and why they got in—preventing repeat problems.
Professionals also know how to safely deploy control methods in homes with pets or children, avoiding the risks of improper bait use or accidental exposure.

This is particularly important for businesses that cannot afford repeat infestations. By scheduling periodic checks and maintaining good prevention practices, long-term rodent issues can be successfully avoided.
