“We use an integrated approach” appears on a lot of pest control company websites, but it is a specific, defined methodology, not a marketing phrase. The British Pest Control Association (BPCA), the UK’s leading trade body for the industry, sets out Integrated Pest Management, or IPM, as the standard its members are expected to follow, and understanding what it actually involves is a useful way to judge whether a quote reflects genuine professional practice.
What IPM actually means
According to BPCA’s own published guidance, Integrated Pest Management is a sustainable approach to managing pests that combines biological, cultural, physical and chemical tools in a way intended to minimise economic, health and environmental risk, while still protecting people, food and the wider environment. The defining feature is not that chemicals are never used, but where they sit in the sequence of methods applied. As BPCA puts it, the difference between IPM and a traditional approach is the point at which chemicals are used: at one extreme, chemical treatment is reached for immediately; under a genuine IPM approach, it is the last resort after other methods have been assessed and, where possible, applied first.
The methods that come before chemical treatment
Biological controls use a pest’s natural predators, parasites or competitors rather than chemical agents, though this is more commonly seen in agricultural and amenity settings than a typical domestic pest problem. Cultural controls address the conditions that let a pest thrive in the first place, removing accessible food sources, fixing damp conditions that attract certain insects, and changing storage or waste practices so a property is simply less hospitable to the pest in question. Physical controls include proofing, trapping, exclusion and mechanical barriers, sealing entry points, fitting bird netting, or using traps rather than poison where that achieves the same result. Only once these options have been genuinely considered, and where they are insufficient on their own, does a proper IPM approach move to targeted chemical treatment, and even then the aim is the most proportionate product and application method for the specific pest and setting, not the broadest possible spray.
Why this sequencing actually matters, beyond ideology
IPM is not simply a more cautious or environmentally conscious label. Pests that survive repeated chemical exposure without other controls addressing the underlying cause can develop resistance, and treating the same recurring infestation with the same spray each time it reappears, without identifying and fixing entry points or food sources, is a genuine and well-documented failure mode in pest control. A company following IPM properly should be identifying why a pest problem exists at your property, not just what to spray to knock down the current visible activity, which tends to produce more durable results and fewer repeat callouts.
What to look for in a genuinely IPM-led quote
A pest controller working to IPM principles should be able to explain their assessment of your specific property: where the pest is likely entering or nesting, what is attracting it, and which physical or cultural changes they recommend alongside, or instead of, chemical treatment. If every quote you receive for the same problem consists solely of “we will spray X,” without any inspection-led explanation of cause, that is a reasonable signal the company is not actually applying IPM, whatever the word appears on their marketing material. BPCA membership itself is a useful, though not conclusive, indicator, since member companies are expected to operate to this standard as a condition of membership, and BPCA’s public register lets you check whether a specific company is currently listed.
It is also worth asking directly what non-chemical measures are included in a quote, since proofing and exclusion work is sometimes priced as a separate, optional extra rather than integrated into the treatment plan itself. A cheaper quote that consists purely of chemical treatment, with proofing offered only afterwards at additional cost, may end up more expensive over time if the pest simply re-enters through the same unaddressed gap.
How IPM changes what a “successful” treatment looks like
Under a purely chemical approach, success is often measured narrowly: are pests visibly present today, yes or no. IPM asks a broader question, because a treatment that kills the current population but leaves the entry point, food source or damp condition unaddressed has not actually solved the underlying problem, only paused it. A genuinely IPM-led pest controller should be willing to explain what they expect to happen after treatment, including a realistic timeframe for the pest to stop reappearing and what signs would indicate the underlying cause has not actually been fixed, rather than simply confirming a callback is available if needed.
This also affects how contracts are structured. A one-off spray treatment with no proofing or monitoring component is sometimes the right answer for a genuinely isolated, one-time pest incursion, but a recurring problem, mice returning every autumn, wasps nesting in the same eaves each summer, is a signal that a single chemical treatment without an IPM-style root-cause review is being used to manage a problem it was never designed to solve.
