Ant Control London

If you’ve spotted a trail of ants marching across your kitchen worktop, you’re not alone. Ants are one of the most common pest complaints in London homes, especially between March and October, when warmer weather brings colonies out foraging for food.

The good news: ants are one of the more straightforward pests to deal with, as long as you treat the nest itself, not just the ants you can see. Spraying the trail on your worktop kills the workers in front of you. But it leaves the colony - and the queen - untouched. That’s why DIY sprays so often seem to “come back” within a week or two.

Signs you have an ant problem

• A visible trail of ants, usually following the same route to a food or water source
• Small piles of soil or sawdust-like debris near skirting boards, patios, or garden paving (a sign of nest activity)
• Ants appearing suddenly indoors after rain (garden colonies often move inside when their nest floods)
• Winged ants indoors - this can indicate a mature colony preparing to swarm and establish a new nest

Why ants are so common in London properties

London’s mix of Victorian terraces, converted flats, and gardens backing onto shared walls gives ants easy routes indoors - through worn mortar, gaps around pipework, and cavity walls. Ants are also drawn to the warmth of centrally heated homes during cooler months, and to any kitchen with accessible food, pet bowls, or bins.

Our Ant Control Process

1. Inspection - we identify the ant species (garden black ants and, less commonly, pharaoh ants which require a different approach), locate the nest or likely nest area, and check entry points.
2. Targeted treatment - gel baiting and non-repellent insecticide are used so worker ants carry the treatment back to the nest and colony, rather than simply killing the ants you can see. This is the single biggest reason professional treatment outperforms shop-bought spray.
3. Crack and crevice sealing - closing off the entry points ants are using reduces the chance of a repeat problem.
4. Follow-up - a check-up visit within the guarantee period if activity continues.

What does ant control cost in London?

Ant treatment is £190 for a flat and £220 for a house. That covers the inspection, finding the nest and the treatment itself, and if the ants come back within 60 days we return free. Pharaoh ants are a different job.

They turn up more in flats, food premises and buildings with shared heating, and they need a two-visit baiting programme, which is £260 for a flat and £290 for a house. You always get the exact price before any work starts, with no hidden charges.

Common in These London Areas

Ant activity is a frequent call-out across North West London (older brickwork and gardens), South East London (larger gardens in the outer suburbs), and Central London (period mansion blocks). Check your area page for local detail, or contact us directly.
