Where Harrow's Wasp Nests Build Up
Eaves above semis in Rayners Lane and Kenton
The semi-detached houses around Rayners Lane and Kenton have eaves and roofline gaps that a queen wasp can use to start a nest well out of sight in spring. By late summer, a nest built into a roof void like this can be the size of a football, with wasps funnelling steadily through a single vent or gap.
Garden sheds around Harrow Weald
The larger gardens stretching out toward Bushey and Harrow Weald give wasps another option — a shed roof or a gap in a garden wall, where activity can go unnoticed for longer than a roof nest because the buzzing blends into other garden noise.
Signs to Look For
- A grey, papery nest the size of a football or larger, usually by late summer
- Wasps repeatedly entering and leaving one spot — a loft vent, eave or air brick
- A low buzzing or rustling sound from inside a wall, loft or shed
- More wasps than usual around bins, fruit trees or open windows
