A termite spot treatment is a targeted pest control method that applies termiticide directly to a specific, localised area of termite activity. It is a quick, focused response to a known problem, rather than a whole-home treatment. Understanding when a spot treatment is appropriate and when you need a full termite barrier helps you make the right decision for your property.
At Bestwest Building, our pest managers carry out spot treatments across Perth as part of our pest control services. In this guide, we explain how spot treatments work, share a real example from a recent job, and help you understand which treatment option is right for your situation.

What Is a Termite Spot Treatment?
A termite spot treatment involves applying a termiticide directly to a specific area where termite activity or a termite nest has been identified. The treatment is localised, meaning it targets only the affected area rather than creating a continuous treated zone around the entire property.
The termiticides used in spot treatments are typically non-repellent products. This means termites cannot detect the chemical and will pass through the treated area, picking up the termiticide on their bodies. When they return to the colony, they transfer the chemical to other termites through contact, gradually eliminating the colony from within. This is known as the transfer effect.

When Is a Spot Treatment Used?
Spot treatments are most commonly used when live termite activity is found during a timber pest inspection, when a termite nest is discovered in a tree or garden area on the property, when termite activity is limited to a small, defined area, or as an interim measure while a full termite barrier treatment is being arranged.
Spot treatments are not a substitute for whole-home protection. They address the immediate problem but do not prevent termites from entering the property through other pathways in the future.
| KEY TAKEAWAY A spot treatment is first aid. A termite barrier is the long-term protection plan. If termites are found inside your home, we recommend proceeding to a full barrier as soon as possible. |
How a Spot Treatment Works
The most common application for spot treatments is to external nests in trees, garden beds, or outbuildings. The pest technician drills into the nest or affected timber and injects a termiticide foam or liquid directly into the termite galleries. The expanding foam coats the termites and the internal surfaces of the tunnels.
It is important to understand that spot treating live termite activity inside the home is a short-term measure only. When termites are active inside a property, treating one area often results in the colony simply moving to another part of the home within a month or two. For this reason, we rarely offer a spot treatment alone when termites are found inside a home. Instead, we recommend proceeding to a full termite barrier treatment as soon as possible to address the issue comprehensively.
For nests in trees or external structures, the technician drills into the nest and injects the termiticide. Even if no live termites are present at the time of treatment, termites returning to the nest will come into contact with the chemical and spread it through the colony.
Real Example: Treating a Termite Nest in a Tree
During an annual timber pest inspection at a Perth property, our pest technician discovered a termite nest at the base of a tree in the front garden. At the time of inspection, no live termites were present in the nest, but there was clear evidence of termite activity, including mudding and frass.
Even though no live termites were visible, our technician carried out a spot treatment. The nest was drilled and injected with a non-repellent termiticide. The rationale is straightforward: termites regularly return to their nest, and any returning termites will come into contact with the treated material and spread it to other members of the colony through normal contact.
This is a common scenario. Termite nests can remain active even when no termites are visible at a given moment. Treating the nest proactively eliminates the risk of the colony expanding and foraging into the nearby home.

Spot Treatment vs Termite Barrier Treatment
A spot treatment addresses an immediate, localised problem. A termite barrier treatment creates a continuous treated zone around the entire perimeter of the home, protecting the property against future termite entry from any direction.
We recommend termite barrier treatments for whole-home protection. A barrier uses the same non-repellent termiticides but applies them in a systematic way around the foundations, ensuring complete coverage. For properties where termite activity has been found, a spot treatment can provide immediate relief while a full barrier is planned.
| Feature | Spot Treatment | Termite Barrier |
|---|---|---|
| Scope | Localised area only | Full perimeter of property |
| Duration | Short-term relief | Up to 8 year lifespan |
| Best for | External nests, interim measure | Whole-home ongoing protection |
| Indoor use | Short-term only, termites relocate | Prevents entry from all directions |
What Chemicals Are Used?
Professional pest managers in Perth typically use non-repellent liquid termiticides or foams for spot treatments. These products are designed to be undetectable to termites, which means the insects walk through the treated material without avoiding it.
The specific product used depends on the location and nature of the activity. Your pest manager will explain what they are using and why before the treatment begins.
Can I Do a Termite Spot Treatment Myself?
No. Termite treatments should always be carried out by a licensed pest manager. The chemicals used require proper training to handle safely, and incorrect application can cause termites to scatter to other areas of the home, making the problem worse.
| WHY IT MATTERS Incorrect DIY treatment can cause termites to scatter and become harder to locate. Always use a licensed pest manager for any termite treatment. |

Frequently Asked Questions About Termite Spot Treatments
What is the difference between a spot treatment and a full termite barrier?
A spot treatment targets a specific area of known termite activity. A full termite barrier creates a continuous treated zone around the entire perimeter of the home. Spot treatments address the immediate problem, while barriers provide long-term, whole-home protection against future termite entry.
Will a spot treatment kill termites immediately?
Non-repellent termiticides do not kill termites on contact. Instead, the termites carry the chemical back to the colony and spread it through contact with other termites. This process can take several weeks but is designed to gradually eliminate the entire colony.
Can you do a termite spot treatment during a timber pest inspection?
In some cases, yes. If our pest manager identifies termite activity during an inspection, they may be able to carry out a spot treatment on the same visit. This depends on the nature and location of the activity. Your inspector will discuss the options with you on site.
How much does a termite spot treatment cost in Perth?
The cost varies depending on the location and extent of the activity. Spot treatments are generally more affordable than full barrier treatments because they cover a smaller area. Contact us for a quote based on your specific situation.
