Tracking an Ant Trail Back to Its Source in Haringey
Patio gaps in Muswell Hill's gardens
Most of Muswell Hill's 1930s semis have gardens front and back, and a nest under a patio or path finds the gap beneath a patio door an easy route in once a food trail's established. That trail tends to follow the same line day after day until the nest itself is dealt with.
Worn window frames around Crouch End
In the Victorian terraces around Crouch End, it's more often a gap around a worn window frame than a patio door that ants use, working their way from a nest against an outside wall toward whichever kitchen smells most promising.
Signs to Look For
- A steady trail of ants heading to and from a food source
- Small mounds of fine soil near patios, paving or skirting boards
- Ants appearing around windows, doors or kitchen units, especially in warm weather
- Winged ants indoors, which can signal a nest close by
Making Sure the Trail Doesn't Reappear
Treating the trail sorts out what's indoors now; finding and sealing the gap it used is what actually keeps the next one out.
