Cairns’ warm, humid climate can support cockroach activity, so look for a licensed pest controller who can identify the species and inspect likely entry points, kitchens and wet areas. Ask which treatment will be used, how long residents and pets need to stay away, and whether follow-up visits or preventative advice are available. Before treatment, remove food and clutter, clean accessible surfaces and follow the provider’s preparation instructions. Results depend on the infestation, building and treatment used, so compare written quotes and check the operator’s licence and recommendations.
