Go home, wasps. You’re drunk.

Thousands of “boozy wasps” are terrorizing the UK after imbibing the nectar of fermented fruit and cider left behind at pub gardens, Travel + Leisure reports. Experts warn that there’s a greater risk of getting stung at this time of year, especially while boozing outdoors or eating sweet foods.

The sudden change in diet highlights an issue with the insects' food supply: Wasps typically drink a kind of sugar-spit produced by larvae, but the hive queens have already stopped laying larvae by this time of year, and wasps have been unable to get their fill. They also carry a genetic trait that makes them go crazy for sugary foods and alcohol, and other factors have escalated the problem. For one, last year's cold winter translated to an early wasp season, which allowed them to build larger-than-normal nests.

"Wasps have built absolutely massive nests and, now that all the larvae have grown up and the queen has stopped laying eggs, the colonies have a workforce with nothing to do—and nothing to eat," pest control expert Shane Jones told the Daily Mail. "So they go down to the pub, obviously."

What they really want is sugar, which can be found in fermented fruit, cider, and fruity beers. Because wasps are lightweights, just one sip will get them drunk—and you don’t want to see them when they’re tipsy. "Wasps can't handle their booze, so they get tanked-up and fighty—like lager louts,” Jones says. Alcohol can make the insects more irritable and more likely to sting people.

The best way to avoid the problem, according to Dee Ward-Thompson, technical manager at the British Pest Control Association, is to keep the sugary goodies they're craving out of sight. “Maybe the most influential factor on wasp numbers is when people do not dispose of their waste properly, especially food with a high sugar content, such as fruit," Ward-Thompson told the Nottingham Post. “We always advise waste to be securely bagged and held within a clean container, away from where young children might play.”
