Drunk Wasps Are Causing Concern Across England

As summer begins to wind down, people across parts of England are being warned to take extra care around wasps. Pest control experts say the insects can become more troublesome at this time of year as they are attracted to ripe and fermenting fruit.

The unusual behaviour has led to reports of wasps becoming increasingly active around gardens, homes and other areas where fallen fruit is present. While the idea of "drunk wasps" may sound amusing, experts warn that people should not underestimate the risk of being stung.

According to the British Pest Control Association, wasps can feed on fruit that has begun to ferment. The natural fermentation process produces alcohol, which can affect the insects' behaviour. As their colonies reach the later stages of the summer season, workers may also have less of their usual duties to perform.

For householders, the message is straightforward: avoid provoking wasps and do not attempt to interfere with an active nest without appropriate expertise.

Why do wasps become more noticeable at the end of summer?

Wasps are generally more noticeable towards the end of summer and into early autumn. During the warmer months, colonies are busy raising young and gathering food. As the season progresses, the structure and priorities of the colony begin to change.

At this stage, ripe fruit can become an attractive food source. Fruit that has fallen from trees and remained on the ground can start to ferment naturally. The smell can attract wasps, bringing larger numbers into gardens and other outdoor spaces.

This can create a particular problem in areas where fruit trees are common. Apples, plums, pears and other soft or overripe fruit can provide an easy source of food.

The term "drunk wasps" is therefore used to describe insects that have consumed fermented fruit. The effects of fermentation can make them appear disoriented or behave differently from normal.

However, people should not assume that every wasp behaving unusually has consumed alcohol. Wasps can become defensive for a number of reasons, particularly when their nests are threatened.

Are drunk wasps more likely to sting?

Experts have warned that wasps affected by fermented fruit may be more likely to behave aggressively. This is one reason people are being advised to keep their distance.

A wasp does not need to be disturbed directly for a sting to occur. Sudden movements, attempts to swat an insect or accidental contact can sometimes trigger defensive behaviour.

The safest approach is to remain calm and move away from the area. Trying to hit or trap a wasp can increase the chances of being stung.

This advice is particularly important for children, who may be curious about groups of insects around fallen fruit. Parents and carers should explain that wasps should not be chased, disturbed or handled.

What should you do if you discover a wasp nest?

Finding a nest around your home can be worrying, particularly if it is located close to a door, patio, garden path or another frequently used area.

The British Pest Control Association advises that nests should be left alone wherever possible. Wasps play an important role in the environment. Like bees and other insects, they contribute to pollination, while they also help control populations of other garden pests.

Wasps can build nests in surprisingly unusual locations. They may establish colonies in sheds, trees, wall cavities and other sheltered spaces. In some cases, nests can even appear in unexpected parts of buildings.

If a nest is in an area that people rarely use, leaving it undisturbed may be the best option. If it is positioned somewhere that creates a genuine risk, such as near a frequently used entrance, professional advice may be appropriate.

People should avoid attempting to remove or destroy an established nest themselves. A qualified pest controller can assess the situation and determine the safest course of action.

What should you do after a wasp sting?

Most wasp stings cause temporary pain, redness and swelling. For many people, the symptoms are uncomfortable but relatively short-lived.

However, insect stings can cause serious allergic reactions in some individuals. Anaphylaxis is a potentially life-threatening reaction that requires urgent medical attention.

Warning signs of a severe allergic reaction can include difficulty breathing, swelling of the face or throat, dizziness, confusion or a rapid deterioration in someone's condition.

Anyone experiencing symptoms of anaphylaxis should receive emergency medical assistance immediately.

For a more straightforward sting, basic first-aid measures can help reduce discomfort. The British Red Cross has previously advised that, where a visible insect sting is present, the edge of a credit card can be used to scrape it away. The aim is to avoid squeezing the affected area unnecessarily.

People should also seek appropriate medical advice if symptoms become severe, continue to worsen or cause concern.

How can you reduce the number of wasps around your garden?

There are several simple steps households can take to make gardens less attractive to wasps.

Keeping food and sugary drinks covered while eating outdoors is a useful precaution. Rubbish bins should also be properly closed, particularly if they contain food waste.

Fallen fruit should be collected regularly from underneath fruit trees. Leaving large quantities of damaged or overripe fruit on the ground can create an appealing food source for wasps.

It is also sensible to keep an eye on potential nesting areas around sheds, garages and other structures. However, spotting a nest does not mean it should immediately be disturbed.

The most important principle is to avoid unnecessary contact. Wasps are part of the natural ecosystem, and their presence does not automatically mean there is a danger to people.

A seasonal reminder to stay alert

The appearance of large numbers of wasps is a familiar sign that summer is approaching its end. Although reports of insects becoming intoxicated by fermented fruit may sound unusual, the underlying advice is practical.

Avoid disturbing wasps, keep food covered, clear away fallen fruit and give nests plenty of space. Where a nest is located in a high-use area and presents a genuine problem, professional pest control advice can help.

The presence of wasps should not necessarily lead to panic. They perform useful functions in gardens and ecosystems. The key is understanding when they can present a risk and knowing how to respond safely.

For most people, a little awareness can go a long way. As temperatures remain warm and gardens continue to produce ripe fruit, taking sensible precautions can help households enjoy the final weeks of summer without an unwanted encounter.
