How to Get Rid of Cockroaches in Merrylands (and Keep Them Out)

Why cockroaches love Western Sydney kitchens

Merrylands, Granville and the surrounding suburbs offer everything a cockroach needs: warm weather, older brick homes with plenty of voids, and busy family kitchens. The two species we see most often are the small German cockroach (light brown, indoor breeder) and the larger American cockroach (reddish-brown, often coming up from drains).

Step 1 — Identify what you're dealing with

Look for droppings (they resemble ground pepper), shed skins around the fridge motor, and a faint musty smell. If you see one cockroach during the day, there are usually dozens hiding nearby.

Step 2 — Cut off food, water and harbourage

• Wipe benches and stovetops every night
• Store dry goods in sealed containers
• Fix dripping taps and dry sinks before bed
• Seal gaps around skirting, pipework and the dishwasher

Step 3 — Treat with the right product

Surface sprays from the supermarket scatter the colony but rarely kill it. Professional gel baits combined with a residual perimeter spray work because cockroaches carry the active ingredient back to the nest. We use kitchen-safe, low-toxicity products that are approved for use around children and pets.

Step 4 — Follow up after 14 days

Cockroach eggs are protected inside hardened cases (oothecae) and survive most sprays. A second visit two weeks later catches the new hatch before they can breed.

When to call a pro
