Cockroaches are common household pests that can hide in kitchens, bathrooms, laundries and other warm, sheltered areas. They can contaminate food and food-contact surfaces as they move between rubbish, drains and indoor living areas. Their droppings, shed skins and other debris may also aggravate allergies or asthma in sensitive people.
The German cockroach is one of the most troublesome indoor species. It reproduces quickly and often hides in narrow gaps near food, water and warmth. Learn more about how German cockroaches enter homes and why early treatment matters.
Signs You May Have Cockroaches
Seeing a cockroach does not always confirm a large infestation. However, finding several cockroaches, especially during the day, can indicate that more are hiding nearby.
Other possible signs include:
- Small droppings resembling black pepper or coffee grounds
- Brown egg cases in cupboards, drawers or behind appliances
- Shed skins around hiding places
- An unpleasant or musty smell
- Cockroaches appearing after dark
- Activity around sinks, drains, refrigerators and food-storage areas
Our guide to the signs of a German cockroach infestation can help you recognise a developing problem.
Store Food in Sealed Containers
Cockroaches can survive on small amounts of food. Store pantry products in sealed containers and avoid leaving pet food uncovered overnight. Check packaging for damage and clean cupboards regularly to remove crumbs and spills.
Clean Food and Drink Spills Quickly
Clean up crumbs, grease, leftovers and spilled drinks as soon as possible. Pay particular attention to the areas beneath ovens, refrigerators, toasters and other appliances where food debris can accumulate unnoticed.
Good cleaning helps reduce available food, but it may not eliminate an established infestation because cockroaches can remain hidden in cracks, appliances and wall cavities.
Remove Water Sources
Cockroaches need access to moisture. Wipe down sinks and benches before bed, repair leaking taps and pipes, and avoid leaving water in pet bowls overnight where practical.
Check beneath sinks and around refrigerators or dishwashers for condensation and plumbing leaks. These damp, sheltered areas can support ongoing cockroach activity.
Keep Bins Closed and Remove Rubbish
Use rubbish bins with tight-fitting lids and empty them regularly. Clean food residue from the inside and outside of bins, especially around the lid and base.
Recycling should also be rinsed where appropriate. Cardboard boxes, paper bags and clutter can provide hiding places for German cockroaches, so avoid storing unnecessary packaging in the kitchen.
Seal Cockroach Entry Points
Seal gaps around pipes, cupboards, doors and skirting boards. Inspect grocery deliveries, cardboard boxes and second-hand appliances before bringing them indoors because cockroaches and egg cases can travel inside these items.

When to Call a Cockroach Exterminator
Professional assistance may be necessary if you regularly see cockroaches, find egg cases or droppings, or continue to notice activity after improving sanitation.
The treatment method should match the cockroach species, infestation level and property conditions. A technician may use monitoring traps, targeted gel baits, dusts or other registered products as part of an integrated treatment plan. Avoid spraying over professional baits because repellent sprays may interfere with the treatment.
