TL;DR — Spider Control Cost At A Glance
- Most people pay £90 – £200 for professional spider control outside London, rising to £120 – £240 in London and the South East (inc VAT).
- A single treatment covers most homes; larger properties or heavy seasonal invasions may need a follow-up visit.
- Price depends on property size, the number of rooms and external areas treated, and the time of year — autumn is peak spider season in the UK.
- Treatment usually means a residual barrier spray around entry points, eaves, windows and doorframes, plus web removal.
- Reducing the insects spiders feed on — flies and other small bugs — is often the most effective long-term control.
- A BPCA-qualified technician applies residual products safely around children and pets and targets the harbourage points a quick spray misses.

How Much Does Spider Control Cost In 2026?
Professional spider control in the UK costs £90 – £200 on average, rising to £120 – £240 in London and the South East (inc VAT). A single treatment of a typical home sits at the lower to middle of the range, while a large property or a heavy autumn invasion covering many rooms and the full exterior perimeter lands towards the top.
Most UK house spiders are harmless, but for people who find them distressing — or where numbers become overwhelming in late summer and autumn — a professional treatment brings quick relief. The usual approach is a residual barrier: an insecticide applied around entry points, window and door frames, eaves, air bricks and skirting, so spiders passing through pick up a lethal dose. Existing webs are cleared, and advice follows on keeping numbers down.
Here is what you can expect to pay for spider control across the UK:
| How you book | Rest of UK | London & South East |
|---|---|---|
| Single treatment (average home) | £90 – £150 | £120 – £190 |
| Large property / full perimeter | £150 – £200 | £190 – £240 |
| Follow-up / booster visit | £50 – £90 | £70 – £120 |
| Seasonal / recurring plan (per visit) | £70 – £120 | £90 – £150 |

Spider Control Cost By Property Size And Coverage
Spider treatment is priced largely by the area covered — internal rooms, the external perimeter, or both — and the size of the property.
| Scenario | Typical price (rest of UK) | Typical price (London) |
|---|---|---|
| Flat or small terraced house | £90 – £130 | £120 – £160 |
| Semi-detached / detached home | £120 – £180 | £160 – £220 |
| Large property, internal + external | £160 – £200 | £200 – £240 |
| Web removal and perimeter refresh only | £70 – £120 | £90 – £150 |
The cost is almost entirely labour and product. Treating the exterior perimeter as well as the inside costs a little more but tends to work better, because it stops spiders at the point they enter rather than only dealing with the ones already indoors.
What Affects The Cost Of Spider Control?
Several things decide where you land in the ranges above.
1. Property Size And Coverage
A small flat treated internally is a quick job. A large house with a long external perimeter, outbuildings and multiple rooms takes more time and product, pushing the price up.
2. The Time Of Year
Autumn is peak spider season in the UK, when males roam indoors looking to mate. Demand and infestation levels are highest then, and a heavy seasonal invasion may need a more thorough treatment than a quiet spring call-out.
3. The Underlying Food Supply
Spiders go where the food is. A home with a lot of flies and other small insects sustains more spiders, so reducing those — through fly control measures, window screens and lighting changes — often does more for the long term than repeat spraying.
4. Internal Versus External Treatment
Treating only indoors is cheaper but less durable. A perimeter treatment that stops spiders entering costs a little more and generally lasts longer.
5. Access And Harbourage
Cluttered lofts, garages, sheds and cellars give spiders plenty of undisturbed harbourage. Clearing and providing access makes treatment faster and more thorough.
6. Your Location
London and the South East run roughly 20–30% higher than the rest of the UK, reflecting higher labour and travel costs.
What's Included — And What's Not
Typically included in a spider control quote:
- A survey to identify entry points and harbourage
- A residual barrier treatment around windows, doors, eaves and skirting
- Removal of existing webs and egg sacs in treated areas
- Advice on reducing the insects spiders feed on
Usually charged separately or not included:
- Treating the wider insect population that feeds the spiders (a separate service where needed)
- Pest proofing to seal larger gaps
- Loft, cellar or outbuilding clearance to remove harbourage
- Repeat seasonal visits beyond the initial treatment
Always confirm whether internal and external areas are both treated, so the final bill matches the quote.
Can You Do It Yourself?
For most UK homes, spider control is a realistic DIY job, because the common house spiders are harmless. Regular vacuuming of webs and egg sacs, sealing gaps around windows and doors, cutting back plants touching the walls, and reducing outdoor lighting that attracts the insects spiders eat will keep numbers manageable at little cost. Peppermint-oil sprays and sticky traps help some people, though results vary.
Where a professional adds value is with heavy or recurring invasions, or where a genuine phobia makes the problem hard to live with. A residual barrier treatment applied properly lasts far longer than a household spray, and a BPCA-qualified technician reaches the harbourage points — eaves, cavities and loft corners — that DIY misses. If autumn brings an overwhelming influx every year, a professional treatment ahead of the season is the more reliable option.
How To Save Money On Spider Control
- Reduce the food supply — deal with flies and small insects, and swap bright exterior bulbs for warmer, less attractive lighting.
- Seal and cut back — close gaps around windows and doors and trim vegetation touching the walls so spiders have fewer routes in.
- Vacuum regularly to remove webs and egg sacs before numbers build.
- Book ahead of autumn rather than reacting to a peak-season invasion.
- Combine internal and external treatment in one visit for better, longer-lasting results.
- Get 2–3 quotes and compare whether both inside and outside are covered.
How To Hire A Good Pest Controller
Choose a firm that employs BPCA-qualified or RSPH-certified technicians, holds public liability insurance, and gives a written quote covering the areas treated and any follow-up. Ask whether the treatment includes the external perimeter, how long the residual lasts, and what products are used around children and pets. Reviews and references are worth checking before you commit.

Frequently Asked Questions
How Much Does Spider Control Cost In The UK?
Professional spider control costs £90 – £200 across most of the UK, rising to £120 – £240 in London (inc VAT). A single treatment of an average home is cheapest; a large property with full internal and external coverage sits at the top.
Do Spiders In The UK Need Professional Treatment?
Most UK house spiders are harmless, so treatment is usually about comfort rather than safety. Professional control makes sense for heavy seasonal invasions, large properties, or where a phobia makes the problem difficult to manage.
When Are Spiders Worst In UK Homes?
Autumn is peak season, when male spiders come indoors looking to mate. Numbers are highest from late August through October, which is when most people book treatment or seek advice.
How Long Does Spider Treatment Last?
A residual barrier treatment typically stays effective for several weeks to a few months, depending on the product and conditions. Reducing the insects spiders feed on and sealing entry points extends the results.
Does Spider Control Get Rid Of Webs?
Yes. Treatment normally includes clearing existing webs and egg sacs in the treated areas, alongside applying the barrier that deters spiders from returning to those spots.
Is Spider Control More Expensive In London?
Yes. Expect to pay roughly 20–30% more in London and the South East than in the rest of the UK, reflecting higher labour and travel costs.
