NSW Termite FAQ

Termites feed on the cellulose in timber. Subterranean termites found across NSW consume wood from the inside, and the state’s warm, humid climate means the risk is present year-round.

Common signs include mud tubes on walls or foundations, timber that sounds hollow when tapped, sagging floors or doors that stick, small piles of termite droppings (frass), and flying termites swarming near lights at night. Because termites often stay hidden inside timber, a professional inspection remains the most reliable way to catch early activity.

Avoid disturbing them. Don’t spray insecticide, break open mud tubes, or remove damaged timber, as this can scatter the colony deeper into the structure. Instead: stay calm, as termites work slowly so there’s time to act properly; take a photo if you can; mark the location discreetly; call a licensed professional promptly; and leave the area undisturbed until an inspector arrives.

Australian Standard AS 3660.2 recommends an inspection every year. Properties at higher risk, or with a history of termite activity, should consider six-monthly checks.

They’re not a legal requirement, but they’re strongly recommended. Most buyers ask for a pre-purchase pest inspection, and sellers benefit from knowing the condition of the property upfront.

The main options are physical barriers (steel mesh, collars and ant caps), chemical treatments (modern non-repellent termiticides), reticulation systems (which allow chemicals to be reapplied easily) and baiting systems (for monitoring and treating colonies). Grove works with all of these systems and recommends whichever suits the specific home.

Yes, when applied professionally. Modern termiticides are formulated to target termites specifically, with minimal impact on people and pets when strict application protocols are followed.

Yes. The National Construction Code requires a termite management system for all new residential buildings in NSW, installed during construction and documented with council.

A single colony can compromise structural timber within months, and repair costs often run into the tens of thousands of dollars.

Almost never. Insurers generally treat termite damage as preventable through regular maintenance, so it’s excluded from standard policies.

Neither is universally better, they simply serve different purposes. Baiting suits treating colonies with minimal chemical use, while chemical barriers provide long-term perimeter protection. Combining both often gives the most complete protection.

Yes. Grove provides complete termite management, including thorough inspections, colony treatment, barrier installation, ongoing monitoring and warranty programs.

Chemical barriers typically last five to eight years, physical barriers can last twenty-five to fifty years with proper maintenance, bait stations need ongoing monitoring, and reticulation systems are recharged every three to five years. An annual service check confirms the treatment is still effective and accounts for changes to the property, such as landscaping, plumbing or drainage work.

Quality and scope of work differ. A cheap inspection can mean a rushed assessment and missed problems, and a low treatment quote might exclude key areas of the property or use lower-grade products.
