Ant Treatment At A Glance
- Most people pay £100–£200 for professional ant treatment outside London, rising to £130–£250 in London and the South East.
- A single garden or kitchen ant problem is usually cleared in one to two visits, while widespread or repeat infestations may need two to three visits for a lasting fix.
- The price depends on the ant species, how widespread the nest is, your property size, access, and whether the source is indoors or outdoors.
- Standard treatments cover a surveyed area with gel baits, insecticidal sprays or dust, plus advice on stopping ants coming back.
- Pharaoh ants and other tropical species cost more because they need specialist baiting over several weeks rather than a spray.
- Booking early — before ants spread through the kitchen — keeps the job to a single visit and the bill at the lower end.
- Get a fixed price for professional ant treatment — check prices and book online or call to talk through a one-off treatment or a covered plan.
How Much Does Ant Treatment Cost In 2026?
Professional ant treatment in the UK costs £100–£200 on average, rising to £130–£250 in London and the South East. That price typically buys a technician visit, a survey of the affected area, and an appropriate treatment — gel bait, a residual insecticidal spray, or insecticidal dust in wall voids and entry points.
For a straightforward garden ant problem where the trail leads back to a single nest, one visit is often enough, and you will pay at the lower end of the range. Costs climb when the infestation is spread across several rooms, when the nest sits under a patio or deep in a cavity wall, or when the species involved is harder to control. Many firms include a short guarantee period, so if activity returns within a set window a follow-up visit is covered.
Here is what you can expect to pay for professional ant treatment across the UK:
| How you book | Rest of UK | London & South East |
|---|---|---|
| Single treatment visit | £100 – £160 | £130 – £190 |
| Two-visit treatment | £150 – £200 | £180 – £250 |
| Callout with guarantee/follow-up | £120 – £200 | £150 – £250 |
| Recurring commercial/premium plan | from £180 | from £220 |

Ant Treatment Cost By Infestation And Species
Not all ant problems are equal. A trail of black garden ants at the back door is a very different job from a pharaoh ant colony spread through a block of flats. The table below shows how the type and scale of the problem change the price.
| Type of job | Typical price (rest of UK) | Typical price (London) |
|---|---|---|
| Single garden/black ant trail, one room | £100 – £140 | £130 – £170 |
| Multi-room infestation, indoor nest | £150 – £200 | £180 – £250 |
| Pharaoh or tropical ants (specialist baiting) | £180 – £250+ | £220 – £300+ |
| Outdoor nest under patio/decking | £120 – £180 | £150 – £220 |
| Larger property or repeat callout | £180 – £250 | £220 – £300 |
Most garden ant treatments are largely labour and product, with little in the way of materials cost. The bigger driver is time on site and the number of visits — which is why a problem caught early costs far less than one left to spread.

What Affects The Cost Of Ant Treatment?
Several things decide where you land in the ranges above.
1. The Ant Species
Common black garden ants are the cheapest to treat because a well-placed bait or spray at the trail and nest usually does the job. Pharaoh ants, ghost ants and other tropical species are much harder — spraying can actually make them split their colonies and spread, so they need patient gel baiting over several weeks. That extra time and expertise pushes the price up.
2. The Size And Spread Of The Infestation
A single trail from one nest is quick to deal with. Ants foraging across the kitchen, bathroom and several rooms point to a larger colony or multiple nests, which takes longer to survey and treat and often needs a second visit.
3. Where The Nest Is
An accessible outdoor nest in the lawn is simple. A nest hidden under a patio, beneath floorboards or deep in a cavity wall is harder to reach and may need dust blown into voids or repeat baiting, adding to the cost.
4. Your Location
London and the South East run roughly 20–30% higher than the North of England, Wales and Scotland, reflecting higher labour and travel costs. A £120 treatment in the Midlands is often £150–£160 for the same work in the capital.
5. Number Of Visits And Guarantee
A one-off visit is cheapest, but many infestations need two to three visits to break the colony's life cycle. Treatments that come with a guarantee period — where follow-ups are included if ants return — cost a little more up front but protect you from paying twice.
6. Property Type And Access
A small flat is faster than a large detached house with a big garden and multiple entry points. Restricted access, blocked-off voids or the need to move units and appliances all add time.
What's Included — And What's Not
Typically included in an ant treatment price:
- A survey to identify the species and locate nests and trails
- Application of gel bait, insecticidal spray or dust to affected areas
- Treatment of entry points and, where relevant, external nest sites
- Advice on preventing ants returning
- A short guarantee period with many providers
Usually charged separately or excluded:
- Extra visits beyond the agreed treatment (unless covered by a guarantee)
- Major structural work to seal large entry points (pest proofing)
- Treating unrelated pests found during the visit
- Ongoing recurring plans for commercial premises
Always get the scope in writing before work starts, so the final bill matches the quote.
Can You Do It Yourself?
For a minor garden ant trail, DIY is realistic. Shop-bought ant bait stations, gel baits and sprays cost £5–£20 and work well against common black ants if you place bait on the trail and let the workers carry it back to the nest — resist the urge to wipe the trail away before the bait does its job.
Call a professional when DIY baits have not worked after a couple of weeks, when ants keep returning, when there are winged ants indoors (a sign of a mature nest), or when you suspect pharaoh ants. A technician will identify the species correctly, use professional-grade products not sold to the public, and reach nests hidden in walls and under floors that a spray can never touch. Getting the species right matters — the wrong DIY approach with pharaoh ants can make the problem far worse.
How To Save Money On Ant Treatment
- Act early — treat a small trail before it becomes a multi-room infestation and a two-visit job.
- Keep the source clear — clean up food debris, store food in sealed containers and wipe down surfaces so baits stay the most attractive option for the ants.
- Bundle pests — if you have more than one issue, ask about treating them in a single visit rather than separate callouts.
- Choose a treatment with a guarantee so return visits are covered rather than charged again.
- Get 2–3 quotes and compare what's included, not just the headline price.
- Do the prep — clear access to skirting boards, units and suspected nest areas so paid time goes on treatment, not moving furniture.
How To Hire A Good Pest Controller
Ant treatment involves professional insecticides, so it pays to choose a qualified, insured technician. Look for membership of the British Pest Control Association (BPCA) or the National Pest Technicians Association (NPTA), and check that technicians are trained and certified to handle and apply pesticides safely. Confirm they carry public liability insurance, ask for reviews or references, and get a written quote that spells out the treatment, the number of visits and any guarantee.
A good technician will identify the species before treating, explain what they are using and why, and give you clear prevention advice rather than just spraying and leaving.

Frequently Asked Questions
How Much Does Ant Treatment Cost In The UK?
In 2026, professional ant treatment costs around £100–£200 across most of the UK, rising to £130–£250 in London and the South East. Species, spread and the number of visits needed all affect the final price.
How Many Treatments Are Needed To Get Rid Of Ants?
Most common garden ant problems clear in one to two visits. Larger infestations, hidden nests or tropical species such as pharaoh ants can need two to three visits over a few weeks to break the colony's life cycle.
Is Professional Ant Treatment Worth It Over DIY?
For a small trail, DIY bait often works. Professional treatment is worth it when DIY has failed, when ants keep returning, or when you have pharaoh ants — where the wrong product can make the colony split and spread. Technicians use stronger products and reach hidden nests.
Does Ant Treatment Come With A Guarantee?
Many providers include a guarantee period — often several weeks to a few months — during which return visits are covered if ants come back. Always check what the guarantee covers before booking.
How Long Does Ant Treatment Take To Work?
Gel baits and sprays usually cut activity within a few days to two weeks, as workers carry bait back to the nest and the colony declines. A hidden or large nest can take longer, which is why a follow-up visit is sometimes needed.
Are Ant Treatments Safe For Children And Pets?
Professional products are applied by trained technicians and are safe once dry, but you will usually be asked to keep children and pets away from treated areas for a few hours. Your technician will give you specific advice for the products used.
