Most Queensland homeowners know termite barriers exist. Far fewer know what type their property has, when it was installed or whether it is still providing any meaningful protection.
Here's a plain-English breakdown:
🐜 Chemical barriers are the most common type in existing homes. A termiticide is applied to the soil around and beneath the structure, creating a treated zone termites cannot cross without being affected. These are not permanent. Most chemical barriers have an effective lifespan of 8 to 10 years depending on the product, soil conditions and whether the treated zone has been disturbed by landscaping, excavation or construction work.
🐜 Physical barriers are installed during construction, typically under the slab and around penetrations. They are designed to force termites into the open where they can be detected during an inspection. Physical barriers do not kill termites but they do make infestations significantly easier to find early.
🐜 Baiting systems use monitoring stations placed around the property. When termite activity is detected, a slow-acting bait is introduced that the colony carries back and shares. Effective but requires regular monitoring to work properly.
The critical point: a barrier that was installed 12 years ago and never inspected is not protecting your home. It may have degraded, been breached or simply expired.
Annual termite inspections exist partly to assess whether your existing protection is still doing its job.
Cure All Pest Control has been installing and inspecting termite barriers across South East Queensland since 1966.
