As the UK braces for a surge in wasp activity this summer, many are finding that enjoying meals outdoors or with windows open is becoming a risk. Experts are warning that "murder wasps" could soon make their way into British homes, with swarms expected to cause havoc between August 12 and the end of the month.

But thankfully, there’s a simple, eco-friendly solution to keep these aggressive insects away without resorting to chemicals or smelly sprays. Dr Nathaniel Green, an expert in insect behaviour, advised: “We’re seeing nests far larger than normal, which means more wasps and more aggression." According to UK pest control data, wasp-related jobs in June this year were up 618% compared to the same month in 2024, and August is meant to be even worse. Experts say the spike is the result of a warm, wet spring, which has created perfect breeding conditions.

According to experts at Express Bi-Folding Doors, the solution can be as affordable as 30p.

Their recommended deterrent involves using the peels of citrus fruits like lemons and oranges. Both of these fruits, with their strong, citrusy scent, are known to repel wasps.

"With oranges costing from just 28p in supermarkets, this is a low-cost, eco-friendly deterrent," they explained.

By placing leftover citrus peels in small dishes near open windows or on outdoor tables, you can create a barrier that wasps find unappealing and thus avoid.

Alternatively, you can use lemon halves studded with cloves, which wasps also dislike.

This combination has a double action: a natural repellent and a decorative air freshener, making it perfect for keeping your outdoor spaces wasp-free.

"Wasps find this smell combination unpleasant, making it a perfect centrepiece for outdoor tables or windowsills," the specialists pointed out.

Regarding the risks of murder wasps, Dr Green emphasised: “Wasps don’t just sting once and fly away. If they feel threatened, they can sting repeatedly, and that venom can be deadly for someone with an allergy. In a swarm, the danger multiplies.”
