Cockroaches are the most common pest call-out on the Sunshine Coast — and also the most commonly mishandled with supermarket products. The subtropical climate keeps them breeding year-round, and once a German cockroach colony establishes in a kitchen or roof void, retail sprays rarely solve the problem.
Professional Cockroach Treatment vs DIY
Supermarket sprays kill cockroaches on contact but don’t reach the colony. German cockroaches in particular develop resistance to common active ingredients quickly. Professional treatment uses a different approach: gel bait applied to harbourage areas that forager cockroaches carry back to the colony, combined with a residual insecticide spray in high-activity zones. This eliminates the source rather than just the visible individuals.
German vs American Cockroaches — Different Treatment Approaches
German Cockroaches
Found inside — kitchens, bathrooms, behind appliances, inside dishwashers. Light brown, 12–15mm, two dark stripes. Breed rapidly (up to 400 offspring per female). Gel bait in harbourage areas is the most effective treatment. Usually resolved in 1–2 visits.
American Cockroaches
Larger (35–40mm), reddish-brown. Found in subfloors, roof voids, drains, and outdoor areas. Less resistant to treatment than German cockroaches but can establish large populations. Treated with perimeter spray, subfloor treatment, and drain application where needed.
How Long Does Cockroach Treatment Take?
Most homes are treated in a single visit of 30–90 minutes. You may see increased cockroach activity in the first 1–2 weeks as gel bait flushes the colony out — this is normal and a sign the treatment is working. Activity should reduce significantly within 2–4 weeks. A follow-up visit is included if needed.

Frequently Asked Questions
Why do I keep getting cockroaches after treating?
Retail products kill on contact without reaching the nest. German cockroaches also build resistance to common active ingredients. Professional gel bait targets the colony source — that’s the difference between eliminating the problem and temporarily reducing visible numbers.
