Why Are Wasps Flying Into Your Aldham Home? Common Causes and Solutions

Knowing what wasps are doing at each stage of the year helps you decide whether a sighting is a passing event or the start of a nest.

Late April and May: the lone queen

The wasp year begins when a queen emerges and goes looking for a site. From late April, depending on the weather, you may see a single large wasp investigating gaps in eaves, walls, chimneys, trees and bushes, or holes in the ground. She may fly into a house through an open window.

At this stage, a single wasp indoors is very likely to be a queen exploring. She is not a threat, but she is worth watching. If you see her disappear into a gap and return, she may be starting a nest.

It is worth remembering that the weather moves the dates. A warm spring can bring queens out earlier and speed the growth of the colony, while a cold, wet spell slows things down. Treat the months in this guide as a rough shape and not as a timetable.

In April and early May, queens can look for sites in unexpected places: the gap behind a hanging basket bracket, the recess of a garage door, a hollow in a fence post. Checking such places each week is a quick job and gives you a chance to see a nest before it grows.

June and July: the workforce arrives

Once the first workers hatch, the colony begins to grow. More wasps appear, and you may start to see steady traffic at a nest entrance. These workers collect protein for the grubs and some sugar for themselves. The colony enlarges gradually, and the first signs of trouble in a house may appear as wasps in upper rooms or around windows.

This is the best time to act. A smaller colony is easier to deal with, and the problem does not have time to grow.

By the end of June many households start to notice a change. Where there was one wasp at the window in May there may now be two or three at different times of day. The signs to look for are consistency and direction: a nest sends wasps out and back along the same line.

The first workers are smaller than the queen and may be mistaken for a different insect. Do not be surprised if the early colony looks slight. A nest that begins as a golf ball in size can be the size of a football by August, and tens of times busier.

August: the peak

By August the colony is at its largest. A nest can hold from 2,000 to 10,000 wasps or more, and there are many more workers foraging. They are drawn to drinks, fruit, bins and barbecues, and they are more likely to enter houses.

Typical August sightings include wasps at kitchen windows, in porches and on the inside of sunny glass. It is also the time when people are most likely to be stung, simply because there are so many wasps about.

August is also when picnics, barbecues and open doors are at their most frequent, which creates a lot of opportunity. Treat the month as the one in which every precaution counts, from covered bins to mesh screens and careful handling of drinks.

On days when the sun comes out after rain, wasps can emerge in large numbers at once. The sudden presence of several in a room is not always an emergency, but if it happens again the next day it deserves attention.

September and October: the decline

As the season turns, the colony stops raising new young and the workers have less to do. They spend more time seeking sugar and can seem aimless. Cooler mornings slow them down, and they may be found sluggish on windowsills.

A nest can still be active on warm days, so do not relax. But individual wasps wandering indoors in autumn are more likely to be strays than evidence of a new problem.

Because it is difficult to tell the quiet end of a colony from a live nest, look at the entrance rather than at stray wasps. If traffic is still heavy on a warm October day, the nest is working, and it is not safe to ignore.

Late-season colonies can also be unpredictable. Without a regular supply of grubs to feed, the workers are less settled and more likely to fly off in different directions, which makes sightings less consistent. Look at the entrance for a clearer answer.

Using the calendar to decide

Compare what you see with the time of year. A single wasp in May is usually a queen, and the right response is to leave a window open and watch. A stream of wasps in July or August needs attention. A few wasps in October are probably stragglers.

Keep notes from year to year. If wasps appeared at the same place last summer, check it early next spring.

A calendar reminder in April to check the usual sheltered spots on the outside of the house costs nothing and often catches a nest in its first weeks.

Write down the dates on which you see a nest or a queen. Over a few years, you will have a record that helps you plan checks and tells the technician how the property has been affected.
