Are Wasps Dangerous? Understanding Stings and Nest Disturbance in Ashley
A nest is small and quiet in spring and large and defensive by late summer, so the same nest poses very different risks depending on the month.
A colony that starts with one insect
Every wasp nest begins small. From late April, depending on the weather, wasps start building in a sheltered spot, and the first workers soon take over the job. At this stage there may be only a handful of insects, and the nest is the size of a golf ball or smaller. It is easy to miss and a minor concern.
That does not mean it should be ignored. A young nest can be treated with little disruption, and removing it early prevents the problems that arrive later. But most people do not know it exists, which is why the worst stings come in summer rather than spring.
Weather plays a part. A mild, early spring can bring nest-building forward, and a cool, wet one can hold it back. That is why the calendar is only a guide, and why you should look for signs rather than wait for a date. A wasp hunting for a site in a shed, loft or bank may be seen drifting slowly along walls and eaves in spring.
Early summer: workers take over
As the first workers emerge, they take over building and foraging. The nest grows quickly. More insects mean more traffic at the entrance, and that is often when householders first notice a flow of wasps going to and from a gap in the eaves, a hedge or a hole in the ground.
The risk at this point is still moderate. A disturbed nest can send out a number of defenders, and a person standing too close can be stung several times, but the colony is not yet at full strength. Early summer is a good time to act: the nest is easier to deal with and there is less chance of anyone being hurt.
Typical sites at this stage include roof spaces, the gap behind a fascia board, a wall cavity, a hole in the lawn, an old compost heap and a quiet corner of an outbuilding. The insect traffic is light, so a nest can easily be missed until the colony has doubled in size.
High summer to August: the peak
By August a colony is at its biggest, and a nest can hold from 2,000 to 10,000 or more wasps. This is the point at which the question of whether wasp nests are dangerous has the most serious answer. A disturbance can bring out hundreds of insects at once, and a person can be stung many times in moments.
It is also the time when wasps are most in evidence around food and drink, and most likely to be met in gardens and at picnics. If you have a nest on your property in August, it is worth treating as a priority and keeping everyone clear until a technician has been.
Heat makes a difference too. On a hot afternoon, wasps are busy and the nest is warm and active, and they may react faster to a disturbance than in a cooler spell. Even so, a quiet morning is not a reason to relax.
The sheer number of insects at this stage is what makes a disturbance serious, so even a short burst of activity near the entrance can lead to a lot of stings.
Late summer and autumn: restless colonies
As the season turns, the colony changes. The workers have fewer grubs to feed, and the insects spend more time looking for sugar for themselves. They can seem more irritable around people, drinks and rubbish. The nest remains defended, and it can be dangerous to disturb well into autumn.
Eventually the colony declines and the old nest is abandoned, but this can be later than people expect, and it is no reason to wait. Meanwhile, the risk of a sting is still real, particularly in the garden.
The old colony fades as the weather cools. Many people mistake this for the end of the problem, but a nest does not stop being a hazard the moment it begins to fade.
What this means for you
The practical lesson is to act early. Look for signs in spring and early summer, and do not wait until August. If you find a nest, keep clear and have it treated, whatever the month. If someone is stung and shows swelling of the face, lips or throat, a wheeze or difficulty breathing, dizziness or a widespread rash, call 999. Treat it as a 999 emergency if the person feels faint, starts wheezing, or shows swelling of the face, lips or throat or a spreading rash.
People with allergies should plan ahead with their GP before the busiest part of the season.
A simple calendar helps: a look round in May for early signs, another in June, and a regular glance through July and August. It takes five minutes and costs nothing. Make a note of anything unusual, and ring for advice if in doubt.
Children can join in as spotters from a safe spot, which turns it into a useful habit and not a worry.
