Why Are Wasps Flying Into Your Belchamp St Paul Home? Common Causes and Solutions

As summer fades, many people wonder whether a nest is worth treating or will die back on its own. The answer depends on what it is doing now.

What happens to a colony late in the year

A colony begins in spring and grows through the summer, reaching its peak around August. As autumn approaches, it stops raising new young, the workers have less to do and the numbers begin to fall. In time the colony dies out.

This is the point at which people ask whether to bother. The answer is that the nest can remain active for a while, and until it has stopped it is still a hazard.

The pace of decline varies from one colony to the next. A nest in a sheltered, sunny spot may remain busy for longer than one in a cool, shady position. The weather matters too, since a mild autumn can extend activity by weeks.

The empty nest left behind is of no use to the next queen, but it may be a source of concern if it is large or in an awkward place. Raise this when you book.

How to judge if it is still active

Watch the entrance on a warm afternoon. A busy stream of wasps going in and out means the nest is working. Few wasps, or none, suggests the colony has declined.

Other indicators:

• Wasps still entering the house from the same direction.
• A hum in the wall or ceiling on warm days.
• Wasps becoming bolder at windows and food.
• No wasps on cold, wet days but plenty on warm ones.
• Fresh paper-like fragments near the entrance.

If you are unsure, watch on two or three separate days at different times.

If you can safely observe the entrance, count the wasps that enter in a minute, then repeat at the same time on another day. A clear fall suggests decline. An unchanged or increased count suggests a nest still going strong. Use this simply as a rough guide, and always from a distance.

Take care in the garden on mild afternoons in September and October. The numbers feeding on windfalls and ivy flowers can look alarming, but they are not necessarily from a nest on your property.

The temperature at the time of watching has a strong effect. On a cool morning, very few wasps will fly, even from a healthy nest, and the entrance may look empty. Wait for the warmest part of the day before drawing conclusions.

Risks of waiting

There are good reasons not to simply wait. Late-season wasps can be irritable and look for sugar in houses. A nest that is still active may have thousands of wasps, and disturbing it can provoke a swarm. In buildings, a nest in a loft or wall can cause staining and mess even after the colony has died.

If wasps are still entering your home, or if someone in the household is allergic, waiting is not a good idea.

A late nest also poses a particular risk because workers that are no longer needed to feed grubs become more restless and range further, which increases the chance of encounters with people. Autumn stings are common for this reason.

There is also the matter of timing. If you leave a nest until it has quietened and then find that wasps are still entering the house in the meantime, you have lost weeks of comfort for no gain.

When waiting is reasonable

If a nest is well away from the house, in a place nobody goes, and wasps are no longer entering your home, it may be acceptable to leave it and keep clear. Make sure everyone knows to stay away. Avoid pruning, mowing or building work nearby.

An empty nest left in a loft or wall may leave staining or debris. If so, a builder can advise on the clean-up once the colony has stopped.

If you decide to wait, set a date to review. Look at the entrance again in a week, and if activity has fallen to nothing on a warm day, you can reasonably assume the colony has gone. Keep your distance from the nest until you are sure.

Do not be tempted to disturb it in order to see whether it is dead. A nest that appears still may contain live wasps, and a cold morning can fool you into thinking it is empty.

Keeping safe while you decide

Close windows on the side of the nest, cover food and drinks, keep children and pets away from the area, and do not try to block or open the nest. If someone is stung, wash the sting site, remove the sting if visible and apply a cold pack. Call 999 for swelling of the face, lips or throat, wheezing, dizziness or a widespread rash.

Pets are at risk too. Dogs that sniff around a hedge or a hole in the ground can be stung repeatedly, so keep them on a lead near the area.

Keep a list of the signs you have seen and the dates, so that you can make a decision with a clear head instead of reacting to a single frightening afternoon.
