Common Household Pests Found in Sydney

Sydney's climate is kind to people and, unfortunately, just as kind to pests. Warm summers, mild winters and a mix of coastal humidity and leafy suburbs mean homeowners across the city deal with a familiar cast of unwelcome visitors. Here is a rundown of the pests we are called out to most, and what tends to attract them.

Cockroaches

German cockroaches take hold in kitchens and units, breeding quickly in warm, tight spaces near food and water. The larger American and Australian cockroaches tend to come in from drains, subfloors and gardens. All of them thrive where there is moisture and food residue.

Ants

Black house ants, coastal brown ants and the invasive Argentine ant all appear in force through the warmer months. Sweet foods, pet bowls and moisture draw them indoors, and surface sprays often make matters worse by splitting the colony.

Spiders

Sydney has everything from the harmless huntsman to the dangerous redback and funnel web. Redbacks favour sheltered outdoor spots, while huntsmen wander in chasing insects. A spider treatment focuses on eaves, fences and harbourage rather than blanket spraying.

Rodents

Rats and mice move into roof voids and wall cavities as the weather cools. They gnaw wiring, foul insulation and breed fast, so early action matters.

Silverfish and pantry pests

These quieter pests damage books, clothing and stored food in humid cupboards and roof spaces, often going unnoticed until the damage is done.

Birds

Pigeons roost under solar panels and on ledges, fouling surfaces below and blocking gutters. Bird proofing relies on humane exclusion such as mesh and spikes rather than treatment.

What attracts pests to a home

• Food scraps and open pantry items
• Moisture from leaks, poor drainage or condensation
• Clutter and stored goods that provide harbourage
• Gaps around pipes, vents, doors and rooflines
• Gardens and mulch pushed up against the walls
