When it comes to high-end termite protection in Queensland, two names dominate the conversation: Sentricon AlwaysActive and Trelona ATBS. Both termite baiting systems have moved away from “empty” monitoring stations to “Active-on-Application” technology, but they aren’t identical.
In 2026, Brisbane homeowners are asking: Which one actually works faster? And which is better for my specific property?
1. The Core Technology: How They Kill the Colony
Both systems use an Insect Growth Regulator (IGR). This isn’t a traditional poison that kills a single termite on contact. Instead, it stops termites from molting. When they can’t shed their skin, they die—and because they share the bait with the entire nest, the whole colony collapses.
Sentricon: Uses Hexaflumuron. It’s the “Coke” of the industry – the original standard with a massive global track record.
Trelona: Uses Novaluron. It is often called the “faster aggregator,” meaning termites tend to find and start feeding on it slightly quicker in our experience.
2. Station Design & "Findability"
Termites don’t “see” stations; they blunder into them while foraging. This makes the physical footprint of the station vital.
Trelona’s “Waffle” Advantage
Trelona stations are generally wider and have a larger vertical surface area. In the varied soil of suburbs like Upper Kedron or Chapel Hill, this larger “shadow” in the soil makes it statistically more likely that a termite tunnel will intersect with the station.
Sentricon’s Slim Profile
Sentricon stations are slimmer. This makes them excellent for tighter spaces or properties with significant concrete where smaller core-drilled holes are preferred for aesthetics.
3. Maintenance and Inspection Frequency
In 2026, the Australian Standards (AS 3660) still require professional oversight, but the systems vary in how they are managed:
Sentricon AlwaysActive: Typically requires an annual service. The rods are highly durable and can stay active in the ground for long periods without degrading.
Trelona ATBS: While also durable, Trelona’s higher palatability means termites often consume it faster. At Termite Guys Brisbane, we often recommend 6-monthly “digital check-ins” for high-pressure areas to ensure your “Ring of Protection” is never empty.
4. The "Rent vs. Own" Factor
This is the biggest difference most homeowners don’t realize:
Sentricon is often treated as a subscription. Many companies “lease” you the stations. If you stop the service, they may remove the stations from your yard.
Trelona is typically an asset you own. Once installed, the stations belong to your property. You simply pay for the professional monitoring and cartridge refills as needed.
The 2026 Verdict: Which should you choose?
Choose Sentricon if: You want a “set and forget” system with a 20-year history of success and don’t mind a subscription-style service.
Choose Trelona if: You live in a high-activity area (near bushland or old gum trees) and want the fastest possible colony interception and a system you own outright.

Every property in Brisbane is different. A Queenslander on stumps in Ashgrove has different needs than a modern slab home in North Lakes.
