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

Wasps follow the sun, and the hours at which they turn up indoors are a surprisingly good clue to where they are coming from.

Wasps keep a daily rhythm

Wasp activity is driven by temperature and light. On a cool morning, a colony stirs slowly. As the air warms, more workers leave the nest, and traffic builds towards the middle of the day. In the late afternoon, activity tapers off as the sun drops and the air cools.

Because of this rhythm, the times when wasps appear in your home can tell you whether they are following a nest’s routine or wandering in at random.

It is worth noting the time of each sighting for a few days. A simple list on your phone is enough.

Seasonal rhythm also depends on the weather. A hot spell can bring the whole schedule forward, with activity starting earlier in the morning and lasting later into the evening. A cool, damp week does the reverse, and may make you believe that a problem has gone away when the nest is simply quiet.

Early morning sightings

A wasp indoors at breakfast, particularly on the inside of a window, often means it spent the night in the room. It may have come in the previous evening, settled in a curtain or corner and warmed up with the morning sun. It is slow, and it will usually leave if given a clear exit.

A cluster of wasps in the same room first thing in the morning is a different matter. If several appear on a window within minutes of the sun reaching it, they may be emerging from a gap nearby, perhaps a nest behind the window frame or in the wall.

Try the sunlight test. Note which windows catch the first sun, and whether wasps appear there before they appear elsewhere. A wasp that settles on a sunny pane to warm up is behaving normally. Many wasps arriving at a sunlit pane within a short space of time is a signal worth recording.

If you can, also record the weather, using a simple label such as hot, mild or cool. It will help you compare one day with another.

Midday and early afternoon

This is the busiest time. A nest sends out the largest number of foragers, and a house on their route will see more visitors. Wasps that come in during these hours are generally hunting for food or drink, and they will go for the kitchen, the dining room or a table.

Signs that point to a nest at this time include:

• Wasps arriving in a steady stream, not as occasional visitors.
• Insects entering from the same side of the house each time.
• A flight line that passes close to a window or door.
• Wasps carrying away bits of food in a straight line.
• Visits that stop when the sun goes behind a cloud and resume when it returns.

If this describes your day, look at the outside of the house during the same hours.

Keep in mind that your own activity has an effect. Cooking at lunchtime, sitting on the patio with a drink or taking out the bins at midday all coincide with peak wasp hours. If you can shift some of these jobs to the cooler parts of the day, you will see fewer wasps.

Late afternoon and evening

As the day cools, foraging slows and many wasps return to the nest. Wasps that remain in a room at dusk are usually the ones that could not find the way out. They gather at the window or around a light and may be a nuisance in the evening.

Draw the curtains before you turn on the lights, and open a window on the opposite side of the house to give them a route. If a wasp lingers around a lamp, switch it off and open the window; the dark outside is no attraction.

A nest that sends wasps indoors late in the day may be in the roof or wall, since the warmth stored in the structure keeps the colony active longer.

Pets that sleep by a window at dusk may be stung by a wasp that has rested on a sill. Check beds, blankets and windowsills before animals settle for the night.

A cooler evening is also the best time to ventilate a room that has had wasps in it. Open the windows wide on both sides and leave the room for a quarter of an hour.

Using the pattern

Compare your notes with the shape of the day. Sightings clustered around breakfast, with an occasional visitor in the afternoon, suggest strays. Sightings from morning to evening, with a peak at midday, suggest a nest. Sightings that always begin when the sun hits a certain wall suggest the nest is on or in that wall.

Whatever the pattern, do not approach the suspected spot. A colony of 2,000 to 10,000 wasps or more can respond quickly to disturbance.

Write the results on a single sheet, with columns for date, time, room and number. After a week, the shape of the day becomes clear, and you can use it to describe the problem on the phone.
