Create a continuous treated zone that blocks concealed termite entry and protects the structure long‑term.
Why Choose a Chemical Soil Treatment
Continuous Treated Zone
Forms a continuous treated zone tied into slab edges and footings to prevent hidden soil entry.
Low‑Visibility Perimeter Solution
Works as a durable, low‑visibility perimeter solution around existing buildings.
Complements Baiting
Soil treatment prevents new ingress; baiting eliminates active colonies.
What Is a Chemical Soil Treatment?
A chemical soil treatment floods termiticide into the soil around and, where accessible, beneath a building to saturate the soil and form a continuous treated zone. The timbers inside the home are not treated; the soil around the structure is. When the treated zone is complete and in contact with footings/slab, concealed termite entry is prevented.
Regular inspections remain essential to detect any "bridging" (e.g., soil build‑up, garden timbers, or conduits that provide a path over or around the zone).
"Barrier" vs "Treated Zone"
Historically, repellent chemicals created an invisible "barrier" that termites avoided. Modern non‑repellent products create a "treated zone" termites can enter without detecting—becoming affected and transferring the active to nestmates. Both aim to prevent concealed access; neither can stop above‑ground bridging. Annual inspections are recommended.
Professional Application
Continuous treated zones integrate with footings and slab edges to block concealed termite entry.
Repellent vs Non‑Repellent Termiticides
RRepellent (e.g., bifenthrin/Biflex)
Termites detect and avoid the treated soil.
Pros:
- •Robust when the zone is continuous
- •Long service life
- •Cost‑effective
Watch‑outs:
If a gap exists, termites may locate and exploit it.
NNon‑Repellent (e.g., chlorantraniliprole/Altriset, fipronil/Termidor, imidacloprid/Premise)
Termites cannot detect the treatment and pass through, becoming contaminated and sharing it.
Pros:
- •More forgiving of small gaps
- •Strong transfer
Watch‑outs:
- •Typically higher cost
- •Still depends on achieving the most continuous treated zone possible
When Soil Treatments Are Suitable
Suitable When:
- •Clear access for trenching/rodding along the perimeter
- •Construction allows continuity (minimal slab joins/extensions; accessible subfloor)
- •Client prefers a perimeter solution to block new concealed entry
Not Suitable When:
- •Multiple slab joins/extensions that prevent continuity
- •Inaccessible or unsafe subfloors
- •Situations where achieving a complete zone would be overly intrusive or damaging
Policy Note:
We don't install partial "90% barriers." If a continuous zone can't be achieved, we recommend a termite monitoring/baiting system to avoid a false sense of security.
Product Options We Use
Biflex (bifenthrin)
RepellentLongest‑lasting repellent; excellent for robust, cost‑effective protection where a continuous zone is achievable.
Altriset (chlorantraniliprole)
Non‑repellentLow‑toxicity profile and strong transfer; label indicates multi‑year protection; preferred where reduced hazard profile is important.
Termidor (fipronil)
Non‑repellentExtremely effective with excellent soil binding; widely used where moisture movement is present. Environmental considerations apply near waterways.
Premise (imidacloprid)
Non‑repellentEffective transfer and penetration; less durable in wet soils and can be absorbed by plants, so site conditions drive selection.
Note: We use water‑based, low‑odour formulations and avoid solvent‑based products.
What a Soil Treatment Can and Cannot Do
What It Can Do:
- •Designed to prevent concealed termite ingress into the treated building
- •Creates long-lasting protection when properly installed
- •Integrates with building foundations for comprehensive coverage
What It Cannot Do:
- •Not intended to kill distant nests or stop termites appearing in untreated landscaping
- •Cannot prevent termites from "bridging" the zone via garden materials or structural elements
Important Note:
Termites can sometimes "bridge" the zone via garden materials or structural elements. Scheduled inspections are critical to find and fix bridging early.
Precautions Before and After Treatment
Before Treatment:
- •Advise us of pets, allergies, or sensitivities
- •Keep pets secured during application
- •Clear access areas around the perimeter
After Treatment:
- •Avoid contact with treated soil until dry
- •Follow technician advice on landscaping levels
- •Maintain weep holes and timber‑to‑ground separation
Soil Treatments vs Monitoring/Baiting — How to Choose
Choose Soil Treatments When:
A continuous treated zone is feasible and desired for ongoing ingress prevention.
Choose Monitoring/Baiting When:
Continuity is impractical, access is limited, or colony elimination with documented milestones is the priority.

Common Termite Species
SUBTERRANEAN TERMITES
Reticulitermes species
Description
Professional subterranean termite control in Melbourne targets Australia's most destructive termite species. Our comprehensive treatment systems create long-lasting barriers to protect your property investment.
Appearance
Creamy white to dark brown workers (3-4mm) with soft bodies. Soldiers have enlarged heads with powerful mandibles. Swarmers are dark brown to black with two pairs of equal-length wings that break off after swarming.
Behavior
Live in underground colonies of 60,000-1 million individuals. Build distinctive mud tubes to travel between soil and wood sources. Swarm in spring and fall, typically after rain when humidity is high.
Habitat
Require soil contact and moisture. Build extensive underground tunnel systems and mud tubes on foundations, walls, and wooden structures. Prefer softwoods but will attack any cellulose material.
Risks & Damage
Cause 80% of termite damage in Australia. Can consume structural timbers rapidly, leading to costly repairs. Often remain undetected until significant damage occurs. Annual damage costs exceed $1.5 billion nationally.

Chemical Soil Treatment Questions

No. It blocks concealed soil entry to the treated structure. Off‑site nests may persist unless directly targeted or eliminated via baiting.
They can sometimes bridge the zone using soil build‑up, garden timbers, or services. Regular inspections identify and correct these risks early.
We don't recommend partial barriers. Any gap can be exploited and creates false reassurance. If continuity isn't achievable, consider a monitoring/baiting system.
It depends on construction, soil moisture, durability goals, environmental sensitivities, and budget. We'll recommend the best fit for the site.
Service life depends on product, soil type, moisture, and application quality. Repellents like bifenthrin are known for longevity; non‑repellents vary by label and conditions.
