Trace it rather than wipe it away
The scent trail builds with every worker that makes the same round trip, so an ignored line tends to look busier over time rather than less, just as near Uxbridge, where the town centre and the streets around the former RAF Uxbridge land. Cleaning the trail off achieves little, a fresh one gets laid straight away; tracking where it leads is what reveals the colony, whether that's near Harefield, where a village at the borough's northern edge, or elsewhere in the borough.
Ruislip and Northwood's back gardens
The 1930s Metro-land semis of Ruislip and Northwood typically have a garden with a patio behind the kitchen, and the warm, dry ground under paving slabs is exactly what an ant colony looks for. A nest doesn't have to sit right against the house - a low garden wall or path well away from the back door can still send a trail all the way indoors.
Terraced streets near Hayes and Yiewsley
Closer to Hayes and Yiewsley, where gardens are smaller and closer to the canal, a trail is more likely to be following a crack in a shared path or gaps around pipework entering the house, rather than anything under a private patio.
What to leave alone for now
- Spraying the trail, which kills the foragers you can see and leaves the colony intact
- Pouring boiling water into paving, which can damage mortar without reaching the queen
- Filling the entry gap before the nest is dealt with, which sends ants to a new gap instead
- Scattering powders along the trail, which can split a colony into several smaller ones
Closing the way in afterwards
Once the colony has been cleared, go back and seal just the gaps the ants were actually using, whether that's a threshold, a pipe hole or a crack in the mortar, whether that's near Hayes, where dense terraced streets and warehousing close to the Grand Union Canal and the roads, or elsewhere in the borough. Don't seal weep holes or air bricks, doing so just locks damp inside the wall structure, just as near Hayes, where dense terraced streets and warehousing close to the Grand Union Canal and the roads.
Booking ant control in Hillingdon
Ant control in Hillingdon runs £190 for a flat and £220 for a house, and because around West Drayton, where a village-turned-suburb close to the M4 and Heathrow, it helps to say roughly whereabouts in the garden the nest might be when you book ant control, with the rest on the Hillingdon ant control page.
