Termite Barriers Sydney
Chemical & Physical Termite Protection for Sydney Homes
A properly installed termite barrier is the most effective long-term defence against termite damage. Pest Elite installs and maintains both chemical and physical termite barriers across Sydney — using industry-leading products including Termidor, Altriset, and Kordon — backed by manufacturer warranties and our satisfaction guarantee.
Chemical & Physical Termite Barrier Options
Pest Elite installs the full range of termite barrier systems for both existing homes and new constructions. Our technicians are accredited with all major manufacturers and will recommend the right system based on your property type, construction method, and termite risk profile.
Chemical Barriers
- Termidor (fipronil) — the most widely used and trusted liquid termiticide in Australia. The treated zone is undetectable to termites, who carry the active ingredient back to the colony.
- Altriset (chlorantraniliprole) — a reduced-risk alternative, ideal for properties with groundwater sensitivity. Highly effective with an excellent safety profile.
- Biflex (bifenthrin) — a repellent barrier system suited to certain construction types and soil profiles.
Physical Barriers
- Kordon (deltamethrin-treated sheeting) — installed during construction under slabs and around pipes and penetrations.
- Homeguard (stainless steel mesh or particle barrier) — non-chemical options accepted in green building programmes.
Why Choose a Professional Termite Barrier?
Long-Term Protection
A properly installed Termidor barrier provides protection for up to 8 years. Physical barriers last the life of the building. This is far more cost-effective than treating active infestations or repairing structural damage.
Manufacturer Warranties
Pest Elite is an accredited operator with BASF (Termidor) and Exterra, meaning your barrier installation comes with a manufacturer-backed warranty.
Tailored to Your Property
There’s no single barrier solution that suits every home. Our technicians assess your construction type, soil conditions, and risk level before recommending the right system.
Minimal Disruption
Most chemical barrier installations are completed in a single day with minimal impact on your home. We respect your property and clean up completely after every job.
How a Termite Barrier is Installed
- Pre-installation inspection — we assess your property for any existing termite activity before applying treatment. Active infestations must be managed first.
- Soil treatment & trenching — for chemical barriers, we trench and treat the soil around the full perimeter of the structure, including around piers and under concrete paths where required.
- Injection drilling — where a full trench isn’t possible, we drill at regular intervals and inject the product directly into the soil.
- Documentation — we provide a full completion report with a property diagram, product batch numbers, treatment dates, and warranty information.
- Annual inspection — we recommend an annual inspection to confirm the barrier integrity and check for new termite activity.
Frequently Asked Questions
How long does a termite barrier last?
A Termidor chemical barrier lasts up to 8 years and comes with a manufacturer warranty. Physical barriers (Kordon, Homeguard) are permanent — they’re installed once during construction and last the life of the building. Annual inspections are still recommended.
Can a termite barrier be installed after construction?
Yes. Chemical barriers are commonly installed on existing homes. Physical barriers are typically installed during construction, though some products can be retrofitted. Our technicians will advise on the best option for your property.
Do I need to leave my house during installation?
For most chemical barrier installations, occupants don’t need to vacate. We’ll advise you of any ventilation requirements and safe re-entry times specific to the product being applied.
Does a termite barrier mean I don’t need annual inspections?
No. AS 3660.2 still recommends annual termite inspections even when a barrier is in place. Barriers can be breached by soil settling, plumbing leaks, or construction works.
