Look for a Wollongong pest controller who is properly licensed in NSW, carries insurance and clearly explains the treatment, expected results and follow-up options. Ask for a written quote covering inspection, preparation, chemicals, warranties and any return visits, rather than comparing price alone. Tell the provider about children, pets, allergies and any tenants or strata requirements before treatment. For termites, extensive infestations or suspected structural damage, consider an independent building or pest inspection as well as advice from a qualified professional.
