The short answer
Neither wins every time. A chemical barrier such as a Termidor treated zone protects the house edges, while a baiting system such as Trelona ATBS targets the colony. Access, soil, house type and budget decide it. Bruin installs both, so the advice follows what your inspection finds.
How does a chemical termite barrier work?
A chemical barrier puts a treated zone of soil around and under the parts of the building termites could use to get in. Termidor, the product Bruin uses, is a liquid termiticide. It's non-repellent, so termites don't detect it and walk through the treated soil. It's designed so termites that pick it up can pass it on to others in the colony.
The technician trenches along the perimeter, drills and injects where concrete meets the walls, and treats around piers and stumps. The barrier protects the building edges, and it needs to be continuous to work.
How does a termite baiting system work?
A baiting system puts stations into the ground around the property. Trelona ATBS, the system Bruin installs, holds bait that termites feed on and carry back to the colony. The bait is an insect growth regulator, which interferes with the way termites moult, so the colony declines over time.
The key word is time. Baiting isn't a same-day fix. A technician has to check the stations on a schedule and replace bait once termites have fed on it. That ongoing monitoring is part of what you're buying.
Termite bait vs chemical barrier side by side
Here's how the two compare on the things people ask about most.
| Termidor treated zone | Trelona ATBS baiting | |
|---|---|---|
| What it is | Liquid termiticide applied to soil around and under the building edges | Bait stations installed in the ground around the property |
| How it works | A treated zone termites cross, with the product passed on between termites | Termites feed on the bait and carry it back to the colony |
| Where the work happens | Trenching, drilling and injecting at the perimeter, piers and slab edges | Stations placed at intervals around the house and grounds |
| Disturbance on install | Higher, because of trenching and drilling | Lower, because stations go into small holes in the ground |
| Ongoing work | Regular inspections, and the zone kept undisturbed | Regular station checks and bait replacement |
| Speed | Protection starts once the zone is complete | Slower, because the colony declines over time |
| Weak spots | Gaps from paths, pavers or later digging | Termites have to find the stations, and the stations have to be checked |
| Bruin installs it | Yes | Yes |
Which suits a slab home, a Queenslander or a unit?
House type matters, but it doesn't decide alone. This is how we think about the common Brisbane builds. An inspection can change any of it.
- Slab-on-ground brick home: concrete paths and patios against the walls make a barrier a drilling job. Baiting avoids the drilling where access is tricky, and a barrier suits a home with open edges.
- Queenslander on stumps: the open subfloor makes stumps and soil easier to reach for a barrier. Older timber and mature gardens are where baiting stations earn their place too.
- Units and townhouses: shared walls, common property and body corporate rules limit where you can drill or place stations, so check who owns the treatment area first.
- Sites where drilling is hard, such as heavy paving, pools close to the walls and retaining walls: baiting or a mix of both is often on the table.
- Sites with a known active colony: the plan starts with treating that activity, then choosing the long-term protection.
Budget matters too, and it's fair to raise it. We'd rather price the option that fits your home and tell you what the alternative would involve.
Can you use both?
Yes. Some properties get a barrier on the edges that are easy to treat and stations where drilling isn't practical. Bruin installs both Termidor treated zones and Trelona ATBS, plus ongoing monitoring, so the mix can follow the house instead of a single product.
What doesn't either system do?
Neither is a force field. A barrier can be bridged by termites building tubes over it, or broken by digging and paving. Stations only work when termites find them. Neither removes the need for inspections.
AS 3660 recommends checking at least every 12 months, and a termite inspection is how a broken zone or an untouched station gets noticed. Fix leaks, keep garden beds and mulch off the walls, and don't stack timber against the house.
What should you ask before choosing?
Put these to every company you get a quote from.
- Which system are you recommending for my house, and what did you find that led to it?
- Where will you drill, trench or place stations?
- What ongoing visits are included, and what do they cost?
- What paperwork do I get, and what conditions come with it?
- What could void it, such as new paving or garden beds?
