How Much Does Ant Treatment Cost in Greenwich?

The Published Price

The One House Price That Is Different

Rat, mouse and cockroach control are all £240 for a house. Ant treatment is £220. That is not a rounding decision - it reflects a genuine difference in what the visit has to cover.

A rodent survey in a house has to look inside the building as well as outside it: the subfloor, the roof void, the service penetrations, the internal runs. Any of them can be where the problem lives.

An ant job is almost always the reverse. The colony is outside - under paving, against a garden or yard wall, beneath a doorstep, in made-up ground beside the building - and the inside of the house is simply where the workers have found something worth carrying home. Following the trail out and treating the colony is a more contained piece of work than assessing every void in a property, and the price says so.

What the Spray in Your Cupboard Actually Costs

A household ant spray is a few pounds and it kills the workers it lands on. Workers are the disposable part of a colony: they are produced continuously, and the queen producing them is not on your kitchen floor. Kill the trail on Monday and more arrive by Wednesday, because nothing that mattered changed.

That is the harmless failure. The expensive one is this: heavy chemical disturbance around a nest can cause the colony to fragment. It splits and relocates into several smaller nests in new places. One trail becomes three, in three parts of the building, and the job you eventually pay for is considerably harder than the one you would have paid for in the first place.

So the honest arithmetic on DIY ant spray is not "a few pounds versus the published price". It is a few pounds, plus the published price, plus a job that is now harder than it needed to be.

Why Baiting Looks Slower and Is Not

Bait placed on an active trail is carried back to the nest by the workers, which is what reaches the part of the colony actually producing the problem. It works precisely because it is slow - the workers have to survive long enough to get home and share it.

Activity often increases briefly after baiting before it drops away. That is the treatment working, not failing, and it is worth knowing in advance so you are not tempted to reach for the spray again halfway through.

Flying Ants Are Not an Infestation

For a short spell each summer, mature nests release winged males and new queens at roughly the same time across a wide area. It is dramatic, it is brief, and it is not a reason to book a treatment for the house they emerged next to.

What it does tell you is that there is a mature nest nearby - useful if you have been getting a trail indoors and have not been able to work out where from. Treating the swarm itself would be selling you something that solves nothing.

When We Will Tell You a Result Will Be Temporary

If the nest turns out to be established in a neighbouring garden or under shared paving, treating your side of the boundary buys you a season. We will say that before you book rather than after, because a temporary result sold as a permanent one is how a customer ends up paying twice and trusting nobody.

Ground-Floor Flats, Gardens and Commercial Yards

Ground-floor and garden flats produce most of the ant enquiries we take, because a nest under a patio or a doorstep is only centimetres from the inside of the building. Upper-floor flats get ants far less often, and when they do the route is usually a cavity or a service riser rather than the front door.

In commercial premises the pattern is the same with different scenery: a trail running to a staff kitchen, a bin area or a spillage, with the nest under hard standing outside. Nests under paving are frequently more accessible than ones under a garden, which occasionally makes a commercial job simpler than a domestic one.

When One Treatment Is Enough, and When It Is Not

Most ant jobs are resolved in a single treatment, and it is worth being specific about which ones are not, because that is where expectations go wrong.

Usually one treatment

A single colony under a path, a doorstep or a patio slab within the property boundary, with one clear trail into the building. Bait goes onto the active trail, the workers carry it home, and the colony is dealt with. Activity often rises briefly before it drops.

Usually more than one

A property with several separate trails entering at different points, which generally means more than one colony. A previously sprayed property where a colony has already fragmented into smaller nests. And any situation where the nest is established on the other side of a boundary.

That last one is the honest limit of what we can do. Treating your side while a mature colony sits in the neighbouring garden buys you a season, and we will tell you that before you book rather than presenting a temporary result as a permanent one.
