Overview
- Experts say the most likely window for Flying Ant Day in 2026 is between 7 July and 20 July, with peaks in mid-July and earlier appearances in cities and southern regions.
- Flying Ant Day is the seasonal mating swarm when winged males and queens leave nests to mate and start new colonies, a behaviour timed to reduce predation.
- Pest-control firms and lifestyle writers recommend sprinkling ground cinnamon along ant trails, at cracks, on windowsills and around pots as an inexpensive barrier that disrupts ants' scent navigation.
- Cinnamon powder is widely available in supermarkets for about 85p and can be reapplied after wind or rain; some experts note concentrated cinnamon or cinnamon oil can act as an irritant or insecticide rather than a colony kill.
- Home teams are advised not to squash ants because that releases alarm pheromones that attract more individuals, and to vacuum indoor sightings instead while recognising ants also play beneficial ecological roles.
