If you’re comparing quotes or just want to know what to expect before booking, here’s a straight breakdown of what ant control actually costs in London right now, and what changes the price.

Garden Ant Treatment

Typical cost: £180–£230

This covers inspection, identifying the nest location, and gel bait treatment targeting the colony rather than just visible ants. Most gardens or single-room indoor infestations fall in this range.

What pushes the price up:

• Multiple nests found on the same property
• Nest located somewhere hard to access (inside a cavity wall, under a large area of paving)
• A follow-up visit needed if activity continues past the initial treatment window

Pharaoh Ant Treatment

Typical cost: £250–£400

Higher than garden ants because of the extended, multi-visit baiting programme pharaoh ants require — usually several weeks of monitoring and rebaiting, since disturbing the colony too aggressively can cause it to split and spread.

What pushes the price up:

• Treatment needing to be coordinated across multiple flats in a shared building
• Commercial kitchens or healthcare settings, which often need documented, compliant treatment plans
• A more established infestation found across several rooms or floors

What’s Usually Included

• Full property inspection and species identification
• Targeted gel baiting (not blanket spraying)
• A written guarantee period, with a follow-up visit if activity continues
• Advice on entry point sealing to reduce recurrence

What Can Make a Quote Higher or Lower Than These Ranges

• Property size — a small flat vs. a large family home with multiple affected rooms
• Access — ground floor vs. difficult-to-reach areas like lofts or cavity walls
• Number of visits needed — most garden ant jobs resolve in one to two visits; pharaoh ants typically need more
• Commercial vs. residential — commercial premises, especially food businesses, often need a documented treatment plan for compliance purposes, which adds to cost
