You're not just imagining it, there really are more wasps around this summer than usual – and experts say the warm, dry spring is the cause.
According to the Met Office, the spring of 2025 was the warmest and sunniest on UK record. Normally, cooler, wetter springs interrupt wasp colony establishment by wiping out young workers. But this year’s weather allowed more to survive, including queens, which meant nests could be created ahead of schedule.
The result this summer is an increase in both the number and size of colonies compared with previous years. Not only does this mean the black and yellow insects are here earlier than normal, but in greater numbers, too.
Why more wasps is good
While their presence can feel intrusive, experts highlight that wasps are vital pollinators and natural pest controllers. "Many of our often-overlooked insects are important pollinators for all kinds of plants, including those which we rely on like fruit trees," says The Wildlife Trusts' website.
Wasps also make a tasty meal for many other animals, including birds, mammals and other insects.
