German cockroaches thrive in Sydney apartments because kitchens are compact, moisture is constant, and plumbing risers connect units. Spotting one at night usually means a larger population is nearby.
Why apartments are different
Shared walls and services mean activity can return even when your unit is spotless. Broad aerosol sprays often push insects deeper into voids. Targeted gel baiting and crack-and-crevice treatments are usually more effective for strata living.
What you can do between visits
- Wipe benches and stove tops nightly
- Empty the kitchen bin before bed
- Store pet food in sealed containers
- Fix slow leaks under sinks
- Avoid leaving dirty dishes overnight
When to call a technician
If activity returns within a week of cleaning, or you see nymphs as well as adults, professional treatment is the faster path. Bug Safe treats discreetly for rentals and strata homes across Greater Sydney and can advise on follow-up timing if neighbouring units are contributing pressure.
