£180 then £60 — and a straight account of what a spider treatment can and cannot do, because this is the service most often oversold in our trade.
£180 for the first room, £60 for every room after. No cap and no call-out fee.
What matters more than the arithmetic is the expectation. Spider treatment reduces a population for a period. It does not seal a building, and anyone selling you a permanently spider-free house is selling something that does not exist.
| Can | Cannot | |
|---|---|---|
| Population in treated rooms | Substantially reduce | Eliminate permanently |
| New spiders entering | Reduce survival once inside | Prevent entry |
| Webbing | Reduce new web building | Remove existing webs — clear those yourself |
| Duration | Remain active for a period | Last indefinitely |
| Outdoors | Treat around entry points | Treat a garden |
A spider treatment is a reduction, not a barrier. We would rather you knew that before booking than felt misled afterwards.
This is close to the opposite of how bed bug or flea rooms are counted, and people are often surprised by it.

Worth addressing directly rather than skirting. Severe arachnophobia is a genuine condition and its effect on daily life is real — people avoid rooms, cannot sleep, will not enter their own garage.
We will treat on that basis without asking anyone to justify it. But we will also be honest that treatment reduces rather than eliminates, so if the expectation is a house where no spider ever appears, treatment will disappoint regardless of how many rooms are done.
For severe phobia, the physical measures — sealing, lighting, regular web clearing — combined with treatment give a better result than treatment alone.
Webbing in a customer-facing or food premises is a presentation and hygiene matter rather than a preference, and commercial requirements vary too much for these published prices. Tell us about the premises.
No — and for spiders a whole-house treatment is rarely the right approach anyway. The rooms that need it are usually the peripheral ones.
Strongest in the first weeks, reducing over time — faster in a garage or cellar than a heated room.
We would not recommend that as routine. Do the physical measures and treat when activity genuinely warrants it.
Around entry points where relevant, yes. Gardens, no.
For something where treatment genuinely does resolve it — wasp nests across Harrow are £90 fixed cost, guaranteed.
£60, after the £180 first room.
The ones with genuinely persistent activity — usually garages, cellars, conservatories and utility rooms rather than bedrooms.
A substantial reduction in the treated rooms for a period. It does not seal the building.
No. Clearing existing webbing is yours to do — and worth doing before treatment anyway.
No.
We would not recommend a routine annual treatment.
No, and a whole-house treatment is rarely the right approach for spiders.
We will treat on that basis without asking anyone to justify it — but honestly, treatment reduces rather than eliminates.
Tell us which spaces and how persistent it is. We would rather talk you out of a treatment you do not need.
