Perth’s Common Autumn Pests

Perth’s common Autumn pests. As we roll through autumn and the temperature begins to drop, humans aren’t the only locals who like to migrate indoors. As you bump up the thermostat, warm homes also become attractive to pests, providing the perfect shelter to see out the colder months and extend the breeding cycle.

Here at TMO Pest and Weed Management, we see the same common pests appearing in autumn across Perth. Read on as we help you identify them—and then offer some TMO pro tips to help you avoid them.


Despite their relatively short lifespan, cockroach Pest control Perth are known for their resilience and high reproduction numbers, with each female capable of laying over 120 eggs during the summer months—making autumn peak season for cockroach infestations.

Cockroaches are known bacteria carriers and can quickly contaminate food with salmonella, staphylococcus, and streptococcus, while harbouring viruses and triggering both allergic reactions and asthma attacks.

Australian cockroaches usually venture indoors, colonising kitchens and bathrooms in their search for warmth, food, and moisture.

TMO Tip: secure all food items (including pet food and leftover food waste) and eliminate moisture from your kitchen and bathroom.

While termites are typically more active in summer, you can still find many subterranean termite infestations during autumn, with moist, damp environments providing food and shelter.

Subterranean termites operate from a central colony beneath the surface soil but will exploit small cracks and flaws in your home’s concrete slab in their search for food. Once inside, termites can move around your home undetected, causing extensive (and expensive) damage to walls and timber structures.

The two common solutions are termite baiting, and termite treatments Perth — with the suitable solution depending on the size and layout of your home, and the level of infestation.

TMO Pro Tip: With termites posing such serious problems to your home, we strongly suggest you seek professional pest control help for any termite outbreaks.

Rats & Mice 

Warm, insulated homes offer plenty of perfect nesting spots for rodents, who like to make their home in roof spaces, cupboards, and between floors and walls. Usually attracted by food sources—such as dirty surfaces, unsealed pet food, and garbage—rodents can squeeze through tiny gaps (less than 2cm in diameter for mice, and only slightly more for rats), making any small hole an easy entry point to your home.

Aside from stealing and contaminating food, making unwanted noise, and annoying your pets, rodents can cause more serious issues for Perth homeowners—spreading disease, destroying furniture, and chewing through electrical wire (potentially causing a fire risk).

TMO Tip: Seal any cracks, crevices, and holes around your windows and doors; secure all food and food waste, and keep outdoor areas clean and tidy.

Bed Bugs 

Bed bugs are a nasty pest that like to make their presence known in autumn. Commonly found in bedding, clothes, and furniture, bed bugs cause painful bites which can lead to severe itching, blisters, and allergic reactions.

Once bed bugs find their ideal breeding conditions, the infestation can be hard to address without professional help. To compound the problem, bed bugs like to travel, hitching a ride through clothing and bags, making the outbreak hard to contain to a single room.

TMO Pro Tip: clean bedding and carpets regularly, and inspect mattresses and other furniture. If you suspect an infestation, seek professional pest control immediately.
