Where Harrow's Ants Get In
Patio doors in Pinner and Rayners Lane's gardens
The semi-detached houses of Pinner and Rayners Lane mostly have gardens front and back, and ants nesting under a patio or path find the gap under a patio door an easy way indoors once a food trail has formed. The trail tends to follow the same route day after day until the nest itself is dealt with.
Older brickwork around Harrow-on-the-Hill
In the older houses on Harrow-on-the-Hill, ants more often use gaps in worn brickwork or window frames than patio doors, working their way toward a kitchen from a nest against the outside wall.
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
Stopping Ants Coming Back
Treating the trail deals with what's indoors now; sealing the gap it used is what keeps the next one out.
