£190 or £220, depending on the property. But the more useful question is whether you need an exterminator at all — and for ants, quite often you do not.
A flat is £190. A house is £220. A £30 difference, reflecting the property rather than the severity.
The prior question matters more. Ants are the pest where DIY most often succeeds, and where we most often tell people they do not need us. Work through the checklist below before booking anything.
Genuinely — this sequence resolves a large proportion of ant problems, and it costs nothing:
If they are back after that, you have a real problem and treatment is warranted. If they are not, you have saved yourself £190 or £220 and we would rather that than the alternative.

View Ant Control Harrow Weald →For rats and mice the flat-to-house difference is £50. For ants it is £30, and the reason is that ant work is concentrated rather than distributed.
A rodent problem ranges across a whole property — loft, voids, garage, full perimeter. An ant problem is usually one route and one colony, and a bigger house does not automatically mean more of either.
The distinction is what each targets:
| Over-the-counter spray | Professional treatment | |
|---|---|---|
| Targets | The ants you can see | The colony sending them |
| Effect on the colony | None | Direct |
| Typical result | New trail within a day | Activity stops |
| Speed | Instant, briefly | Slower, then permanent |
This is why a treatment that seems slow is often working properly. Reaching a colony through its own workers takes a little time, and that is the mechanism rather than a failure of it.
If this is a restaurant, café, takeaway or food retail business, neither published price applies. Commercial requirements vary too much for a single figure, and documentation frequently matters as much as treatment. Tell us about the premises.
£190 for a flat and £220 for a house, throughout Harrow Weald HA3 and every area we cover. The prices do not change by postcode.
No. Ants are priced by property, because treating a trail properly means addressing the colony and route behind it rather than the room it happens to cross.
No. The published price is the price for the service described.
If the entry route is still open and there is a colony nearby, seasonal recurrence is possible. Sealing the route is what breaks that cycle, and it is worth doing even after a successful treatment.
One price that genuinely never varies — wasp nest treatment in Harrow Weald is £90 fixed cost, house or flat, guaranteed.

Ant work is concentrated on one route and one colony, so property size matters less than it does for rodents.
Often not. Follow the trail, remove the food, clean the route and seal the entry point — then wait a fortnight. If they return, treatment is warranted.
No. Garden ants are normal and largely beneficial.
No — that is building work. We will tell you where the route is.
Neither price applies. Commercial requirements vary too much for a published figure — tell us about the premises.
Because it reaches the colony through its own workers. A spray is instant and temporary; treatment is slower and permanent.
