Why the trail matters more than the ant
Each worker that completes the round trip to food and back strengthens the scent trail for the ones behind it, so a line of ants tends to get busier the longer it's ignored. Wiping the surface clean deals with that day's trail but not the colony that sent it.
Small gardens around Bow and Mile End
The compact gardens typical of Bow and Mile End's terraced houses put a patio or path within a few feet of the back door, giving a colony warm, dry conditions close to the kitchen. Watch the trail on a mild, still afternoon and mark - rather than wipe away - wherever it enters the room.
Sash windows and older frames
Tower Hamlets's Victorian terraces still have a good number of original sash windows, and the gaps around a worn frame or sill are a common entry point that's easy to miss because the trail looks like it starts at the worktop rather than the window.
What to leave alone for now
- Spraying the visible trail, which kills foragers but leaves the colony untouched
- Pouring boiling water into paving joints, which rarely reaches the queen and can crack the slab
- Sealing the entry gap before the colony is dealt with, which just sends ants to find a new one
- Scattering powders along the trail, which can split one colony into several smaller ones
Closing the way in afterwards
Once the colony's dealt with, seal only the specific gaps the ants were using - a threshold, a windowsill, a pipe hole - and leave air bricks and weep holes clear so damp doesn't get trapped in the wall behind them.
Booking ant control in Tower Hamlets
