Choosing among termite control companies takes more than comparing the totals at the bottom of their quotes. A useful proposal should show what the inspector found, where the evidence is, what areas could not be checked, and why the recommended treatment fits your home. Ask each company to explain the treatment, its limits, any follow-up, and what the quoted price excludes. That makes it easier to compare like with like and avoid paying for a plan that is either too narrow or more extensive than the evidence supports. For New Zealand homeowners, the right approach also depends on the property, local conditions and the termite activity identified during inspection.
Before recommending treatment, a company should investigate whether the signs are consistent with termite activity and assess the accessible parts of the property for evidence and possible entry points. A brief look at one damaged board is not enough to understand the scope of a problem. The inspection should consider the building and relevant surrounding areas, while being clear about sections that are hidden, inaccessible or outside the agreed inspection.
Ask the inspector to distinguish observed evidence from assumptions. They may find live insects, damaged timber, shelter tubes or other signs that warrant further investigation. These clues can help direct an assessment, but no single visible sign necessarily confirms the species, extent or cause of damage. If the inspector is uncertain, the company should explain what it can and cannot conclude, and whether further assessment is needed before treatment is chosen.
A useful written report or proposal should identify:
Do not treat a confident-sounding diagnosis as a substitute for a clear explanation. If two inspectors reach different conclusions, ask each to point to the evidence and explain the uncertainty. You can also seek another inspection before agreeing to an extensive or costly treatment.
There is no single treatment plan that fits every property. The appropriate method depends on the termite activity identified, the building’s construction, access, the extent of the affected area and other site conditions. A reputable company should connect its recommendation to those findings instead of presenting the same package for every home.
| Approach | When it may be considered | Potential advantage | What to ask about |
|---|---|---|---|
| Soil-applied treatment | Where the inspection supports treating soil around or beneath relevant parts of a structure | Can address a potential route between soil and building, depending on the product and application | Which areas are included, what access or preparation is needed, and how the company will handle untreated or inaccessible sections |
| Baiting system | Where a company considers monitoring and bait placement suitable for the identified activity and site | Can provide a monitored approach that may involve checks over time | How stations will be positioned, how often they will be checked, what follow-up costs apply, and how results will be reported |
| Targeted timber treatment | For particular affected or at-risk timber where a suitable application is possible | Focuses work on specified areas rather than treating the whole property by default | Whether the treatment addresses the source of activity or only the accessible timber, and whether other measures are also needed |
| Building or site changes | Where inspection identifies conditions that may support termite access or conceal evidence | May reduce contributing conditions and make future inspections easier | Which changes are essential, who will carry them out, and whether the work is included in the pest-control quote |
These are broad treatment categories, not interchangeable products or guaranteed solutions. The company should identify the proposed product or system and explain why it is suitable for the suspected termite type, building and site. Ask whether the plan is intended to control active activity, reduce the chance of further entry, monitor for activity, or combine those aims. A proposal that does not make its purpose clear is difficult to evaluate.
Some homes may need a combination of treatment and practical changes. For example, improving access to a previously obscured area could make monitoring more effective, while addressing a moisture issue may help remove a condition the inspector considers relevant. These steps do not replace treatment when active termites require it, and a treatment proposal should not present general maintenance advice as proof that the infestation has been controlled.
A quote is useful only if you can see what you are paying for. Request a written scope that describes the areas to be treated, the treatment method, preparation requirements and any follow-up visits. If the company has identified parts of the property it could not inspect, ask whether those areas are included in the proposed work or remain outside its scope.
Look for a clear breakdown of the work and any exclusions. A lower total may reflect a smaller treatment area, fewer monitoring visits, or additional work being left to you. A higher price may include more extensive treatment or follow-up, but the amount alone does not demonstrate that the plan is more appropriate. Ask each company to explain differences in scope before comparing totals.
Before accepting, confirm the following in writing:
Ask the company to explain any product-use or access restrictions in plain language and provide the relevant written instructions. Do not assume that a general statement such as “treatment included” tells you where work will take place or what follow-up is covered.
When comparing proposals, use the same questions with each provider. This makes differences in diagnosis and scope more visible and reduces the chance of choosing based on a headline price alone. For an older home, a complex layout or areas with limited access, the quality of the inspection and the clarity of its limitations may matter especially.
The best choice is not automatically the company offering the most treatment or the longest-sounding guarantee. A suitable provider is one that explains the evidence, gives a proportionate plan, identifies uncertainties and sets out what happens after the initial work. A clear, modestly scoped proposal can be more useful than a broad package that does not explain why each component is needed.
Use a short list during each inspection or follow-up call. The answers should help you understand both the treatment and the company’s responsibilities:
Pay attention to whether the answers are specific to your property. A provider should be able to explain a recommendation without pressuring you to decide immediately. If urgent action is recommended, ask what evidence makes it urgent and request the reasoning in the written proposal.
Be cautious if a company recommends a substantial treatment without inspecting the property or clearly explaining the limits of an inspection. Other concerns include a quote that names no treatment areas, a verbal assurance in place of written terms, or a promise that termite damage will be repaired when repair work is not listed in the scope.
Pressure to sign before you have time to read the proposal is another reason to pause. So is a guarantee that sounds absolute but does not specify the service, duration, exclusions or homeowner responsibilities. Ask for the full terms; if they are not provided, do not assume the guarantee will cover future activity or structural damage.
Different companies may reasonably recommend different methods, especially when access or evidence is uncertain. That difference is not automatically a sign that one is wrong. Ask each provider to explain its reasoning and what new information would change its recommendation. If you still cannot reconcile conflicting assessments, consider an independent inspection before committing to major work.
Ask for a completion record that states what was treated, where the work took place and any monitoring or follow-up that is planned. Keep it alongside the quote, inspection report, product information and warranty terms. If the company requires access for later checks, note when those checks are due and who is responsible for arranging them.
Treatment does not repair damaged timber or structural elements unless that work is expressly included. Ask whether a builder or other suitable tradesperson should assess any damage identified during inspection. If your home is attached to other properties or shares relevant structures, ask whether the company recommends coordinating inspection or communication with the property manager, body corporate or neighbouring owner.
Follow the company’s written instructions about access, cleaning and safety, and avoid disturbing treated areas unless advised that it is appropriate. Keep an eye out for renewed signs and contact the provider if you see activity covered by the service terms. General prevention, such as addressing a reported moisture problem or improving access to vulnerable areas, can support ongoing monitoring, but it is not a substitute for the agreed follow-up plan.
Comparing proposals can help you see whether the inspection findings and treatment scope are consistent. It is most useful when each company assesses the property and provides a written explanation, rather than quoting only from a brief description. Compare the work included and its limits, not just the total.
A photograph may help a provider decide what to inspect, but it may not show the full extent or source of activity. Ask whether the company’s recommendation is provisional and what it needs to examine in person. Do not treat a photo-based estimate as a complete inspection unless the provider explains its limits.
Not necessarily. Pest treatment and building repairs can be separate services, so check the written scope for repair work and materials. If damage is suspected, ask who should assess it and whether that assessment is included in the price.
No warranty should be interpreted without reading its actual terms. It may cover a particular treatment or specified follow-up work and may include exclusions or conditions. Ask what the company will do if activity is found again, and whether monitoring or retreatment carries an additional charge.
Compare the evidence each inspector recorded, the areas inspected and the reasons for the proposed method. Differences may reflect limited access or uncertainty, so ask what further inspection would resolve the disagreement. For a major treatment decision, another independent assessment may help clarify the options.
When choosing termite control companies, start with the inspection and make sure the written plan explains the evidence, treatment scope, follow-up and exclusions. Compare quotes only after those details are clear. If you cannot explain what the proposed work is meant to do or what it costs beyond the initial visit, ask for a revised proposal before you agree.
