Top 10 Common Pests in Mandurah Homes — How to Spot Them Early

1. Termites (White Ants)

Termites are one of the most destructive pests in Western Australia. They thrive in sandy, moisture-prone soil and can cause significant structural damage long before homeowners realise they’re present.

Early warning signs include:

• Mud tubes along brickwork or foundations

• Hollow-sounding timber

• Bubbling or peeling paint

• Tight-fitting doors and warped frames

Regular termite inspections are essential in coastal areas like Mandurah.

2. Redback & Common House Spiders

Spiders commonly nest in garages, sheds, letterboxes, roof eaves, and outdoor furniture. While many are harmless, redback spiders are venomous and should always be treated professionally.

Watch for:

• Webs forming in corners or under eaves

• Egg sacs attached to surfaces

• Increased spider sightings around the home

3. Ants

Ants are active year-round in Mandurah due to the warm climate. Kitchens, bathrooms, and outdoor entertaining areas are common hotspots.

Early signs include:

• Visible trails along walls or benches

• Clusters near sinks or pet bowls

• Soil mounds around garden edges

Where there’s a trail, there’s usually a nest nearby.

4. Cockroaches

Coastal humidity makes Mandurah an ideal breeding ground for cockroaches, particularly German and Australian species.

Look for:

• Droppings resembling black pepper

• Egg cases (ootheca)

• Musty odours in cupboards

• Roaches scattering when lights are turned on

Seeing one often indicates a larger hidden population.

5. Rodents (Rats & Mice)

Bushland and ongoing development in the Peel Region often push rodents into homes seeking food and shelter.

Common signs:

• Scratching noises in ceilings at night

• Droppings in cupboards or garages

• Chewed wires or food packaging

• Grease marks along walls

Rodents reproduce quickly and can cause both health risks and property damage.

6. Mosquitoes

Living near estuaries and wetlands increases mosquito activity, particularly during warmer months.

Prevention tips:

• Remove standing water

• Clean gutters regularly

• Install and maintain flyscreens

• Treat outdoor breeding areas

7. Fleas

Fleas are common in homes with pets and can spread rapidly indoors.

Early indicators:

• Pets scratching excessively

• Small black specks in bedding

• Bites around ankles

Prompt treatment prevents full-scale infestations.

8. Silverfish

Silverfish thrive in damp environments and feed on paper products, glue, and fabrics.

Signs include:

• Damage to books, wallpaper, or cardboard

• Small silvery insects in bathrooms or laundries

• High indoor humidity

9. Wasps

Wasps frequently build nests under eaves, in trees, or around outdoor entertaining areas.

Watch for:

• Increased wasp activity in one area

• Visible papery nests

• Aggressive behaviour near seating areas

10. Carpet Beetles

Carpet beetles can damage clothing, carpets, and upholstered furniture.

Early warning signs:

• Small holes in fabrics

• Larvae in wardrobes

• Shed skins near skirting boards
