How Much Does Ant Pest Control Cost in the UK? (2026)

A professional ant treatment in the UK usually costs between £60 and £150. A simple black ants trail in the kitchen is at the lower end; carpenter ants or a nest under patios or inside walls can push the price higher because locating and treating the nest takes longer.

Ant pest control prices at a glance

• Standard garden / kitchen ant treatment: £60–£100

What affects the price

• Ant species: black ants are easier to treat than carpenter ants.
• Nest location: a visible nest is quick; hidden nests under floors or walls need more time.
• Property size: larger homes need more bait and product.
• Follow-ups: some colonies take more than one visit to clear.

What''s included

Most ant treatments include a survey, bait or gel application, and advice on removing food sources. Some companies also treat the exterior perimeter to stop ants coming back in.

Can you get rid of ants yourself?

Ant powders and sprays from the supermarket can kill the ants you see, but they rarely reach the queen. If the colony keeps returning, a professional finds the nest and uses targeted bait that the worker ants carry back to it.

How to keep the cost down

• Keep surfaces clean and store food in sealed containers.
• Treat the nest, not just the trail.
• Deal with carpenter ants quickly — they can cause structural damage.
• Get several quotes if the problem keeps coming back.
