Why Are Wasps Flying Into Your Tinshill Home? Common Causes and Solutions
A single large wasp in spring is often a queen looking for a place to start a colony, and this guide explains why that matters and what to do.
One big wasp in April
It is a mild spring afternoon, the first warm one for weeks, and a wasp the size of your thumb is walking slowly along the top of a curtain rail. It looks larger and heavier than the wasps you remember from last summer, and it is not interested in your sandwich. It seems to be exploring, with unhurried, deliberate movements.
What you are probably looking at is a queen. She has spent the winter sheltering somewhere, and now she is searching for a place to build. The colony that grows from that single insect could, by August, hold 2,000 to 10,000 wasps or more. What you do in these first weeks has more effect than anything you do later.
This is the least well-known cause of wasps flying into the house, and it is the one where acting early pays off most. It applies in Tinshill as it does everywhere else.
Why queens come into houses
Queens wake from late April, depending on the weather and how mild the spring has been. They feed on nectar to build up energy, then start to look for a nesting site. They like spaces that are dry, sheltered and undisturbed: gaps in eaves and soffits, wall cavities, lofts, sheds, garages, hollow trees, and holes in the ground.
A house offers a lot of such spaces. A queen may fly in through an open window or door, or through a gap in the roof, and walk around looking at corners, cupboards, curtains and loft hatches. She may then leave, or she may settle on a spot and begin to make a small nest of chewed wood fibre.
Why does she come inside? Sometimes it is just warmth, or a draught, or the pull of light through a window. Often she is evaluating the building as a home.
Most of the time the search ends without a nest. She finds nothing suitable, or she finds the window and leaves, and the day carries on. The risk is in the cases where she does settle, because the first weeks are quiet and a small nest can be started without anyone noticing at all.
Telling a queen from a worker
There is no foolproof test for a householder, and it is not worth getting close enough to find out. A few general clues help:
- Timing: a lone wasp in spring, before the numbers build, is more likely to be a queen than a worker.
- Size: she can look noticeably bigger than the wasps you see later.
- Behaviour: she walks and investigates slowly instead of zigzagging round food.
- Interest: she ignores food and drink, and heads for corners, gaps and ceilings.
If you see a wasp doing this, do not try to catch or swat it, and do not worry about it too much. Open a window and give it a route out.
Stopping an early nest before it starts
A queen that finds a good gap tends to return to it. You can make that less likely.
- Fit mesh to windows and vents.
- Close the loft hatch and check that it fits.
- Keep shed and garage doors shut when you are not using them.
- Look at the eaves, soffits and roof edges for gaps in spring, from the ground.
- Check air bricks and the area around pipes and cables for gaps.
- Tell the household not to disturb anything that looks like a small, papery lump.
Do not seal a hole you think is in use. A queen or a small group of workers inside may look for another way out, and that may be into the house. If you see wasps going in and out of a gap, leave it alone and book a treatment.
A good habit for spring is a short walk round the outside of the property once every week or two on a warm, calm day. You are not searching for a nest, only for any place where wasps seem to be landing and disappearing. Five minutes, from a distance, is plenty.
When a small nest has started
In the early weeks, a nest is small, the first workers are few, and the signs are light: a handful of wasps using one entrance, a faint rustle in a void, or a small grey ball visible in a shed or under a shelf. It is easy to dismiss them as odd visitors.
It is exactly then that a nest is easiest to deal with, before the colony grows through the summer and reaches its peak in August. If you suspect one, keep well away from it, keep children and pets away, and avoid poking at it. A small nest can still sting if it is disturbed.
If anyone is stung, wash the area, remove the sting if visible and apply a cold pack. Swelling of the face, lips or throat, wheezing, difficulty breathing, dizziness or a widespread rash means a call to 999. People with known allergies should speak to their GP.
