Cockroaches in Perth
Noticed a cockroach in the kitchen or bathroom? Learn what to look for, where cockroaches tend to hide and how to reduce the conditions that attract them.
Common signs of cockroach activity
Cockroaches often remain in dark, protected places, so the insects themselves are not always the first sign of a problem. Keep an eye out for these clues.
Live cockroaches
Repeated sightings around kitchens, bathrooms or cupboards, particularly after dark.
Small dark droppings
Dark specks or marks around appliances, cupboard corners and other sheltered areas.
Egg cases
Small egg cases in cracks, storage areas or places that are rarely disturbed.
Shed skins or odours
Shed insect material and, in more heavily affected areas, a persistent unusual smell.
Worth noting: Seeing one cockroach doesn't tell you how many are present. Repeated sightings, droppings or egg cases are good reasons to investigate further.
Where do cockroaches hide?
Cockroaches tend to shelter close to food, water and warmth. In Perth properties, these are some common places to inspect for signs of activity.
Don't just check where you saw one. Activity can extend to adjacent rooms, cupboard gaps and areas behind appliances.
Kitchens & food storage
Benches, pantries, bins, cupboards and places where food residue collects.
Behind appliances
Refrigerators, ovens and dishwashers can offer warmth and undisturbed spaces.
Bathrooms & plumbing
Sink cabinets, pipes, wet areas and spots with persistent moisture.
Cracks, gaps & storage
Wall edges, joints, cardboard boxes and cluttered, sheltered corners.
What attracts cockroaches to a property?
Persistent cockroach activity often involves one or more of these conditions.
Food sources
Crumbs, grease, pet food, overflowing bins and uncovered food can provide easy meals.
Moisture
Leaky pipes, wet sinks, bathrooms and other damp areas can provide access to water.
Shelter & warmth
Cardboard, stored items, gaps and warm appliance spaces offer places to hide.
Simple ways to make your property less inviting
Good housekeeping and basic maintenance can help reduce conditions that support cockroach activity. They may not remove an established infestation on their own.

Cockroaches in Perth: FAQs
Quick answers to questions about cockroach identification and prevention.
Are cockroaches more active at night?
Many common household cockroaches spend the day hidden and become more noticeable when areas are quiet, particularly at night.
Does one cockroach mean there's an infestation?
Not necessarily. One sighting does not establish the size of a problem. Repeated sightings, droppings or egg cases are stronger reasons to investigate.
Can a clean home still get cockroaches?
Yes. Cleanliness helps, but cockroaches can also seek water, warmth and shelter and may enter through gaps or arrive in stored items and packaging.
Should I treat cockroaches myself?
Housekeeping and maintenance help reduce attractants. If activity is persistent or widespread, professional assessment can help locate hidden areas and guide suitable treatment. Always follow product safety instructions and technician advice.
