Trace it rather than wipe it away
Each worker that repeats the same trip to food and back adds to the scent trail, which is why a line only seems to get busier the longer it's left alone, true near Hounslow too, where the town centre and surrounding streets. 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 Cranford, where housing close to the M4 and Heathrow's northern perimeter, or elsewhere in the borough.
Small gardens towards Chiswick and Brentford
The terraced houses common towards the Chiswick border and around Brentford tend to have compact gardens with a patio close to the back door, and the warm, dry ground under paving slabs there 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 a few metres away can still send a trail all the way indoors.
Osterley's larger plots
Around Osterley, where interwar semis sit on bigger plots with more established gardens, a colony can be settled under an older path or retaining wall some distance from the kitchen, which makes it worth tracking properly rather than assuming the nearest bit of paving is the source.
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, much as it does near Feltham, where housing and trade units close to the roads and rail lines running towards Heathrow. Keep weep holes and air bricks open, blocking them as well only creates a damp problem inside the wall, just as near Osterley, where suburban streets close to Osterley Park.
Booking ant control in Hounslow
