Why Are Wasps Flying Into Your Swillington Home? Common Causes and Solutions
Glass rooms trap heat, light and wasps. This guide explains why conservatories and porches attract them and how to keep them under control.
Why glass rooms collect wasps
A conservatory, porch or sunroom is the first place many people notice wasps indoors, and there is a simple reason. A wasp that comes through a door or vent wants to go back to the light, and a room full of glass is a room full of light in every direction. It flies at one pane, falls back, tries the next, and eventually settles in a corner. The room then holds more wasps by the afternoon than it did in the morning.
Heat plays a part as well. Glass rooms warm up quickly, the air becomes still, and any sweet smell from a plant, a drink or a bowl of fruit stays concentrated. Wasps that would ignore a passing smell in the open garden pick it out inside a warm porch.
The question to ask is therefore not only why the wasps came in, but why they are staying. In most cases, the answer is that they cannot find their way back out.
Summer storms and sudden heat can make the problem worse, because wasps seek shelter as well as light. A porch roof in the shade of a tree is one of the first places they will try.
How they get in
Check each of the following:
- Doors left open for ventilation, especially double doors onto the garden.
- Roof vents and trickle vents, which are often just large enough for a wasp.
- Gaps around the door frame where seals have worn or shrunk.
- Cracks between the glass and the frame, or where a porch meets the main wall.
- Plant pots, hanging baskets and nectar-rich flowers just inside the door.
- Food left on the table, such as a half-eaten snack or a sweet drink.
Fix what you can. A fine mesh over vents is cheap and effective. Replace worn rubber or brush strips along the bottom of a door. Move fruit, drinks and rubbish out of the room, and keep the door closed when the room is not in use. A wasp indoors on a hot afternoon is usually a visitor, not a resident, and it will leave quickly once it has an opening and some quiet.
Do not forget the letterbox flap and the cat flap, if there is one in the porch. Both are used by wasps now and then, and a simple brush strip or cover will keep them out.
Helping a trapped wasp leave
If wasps are bumping against the glass, open the door or window fully and then stand back. Wasps move towards daylight, so opening the side that faces the open garden gives them a clear target. Closing the internal door to the rest of the house stops them wandering further in. Leave the room for ten or fifteen minutes and return quietly.
Do not swat at them or squash them against the glass. An annoyed wasp is far more likely to sting. If you must remove one, a glass and a stiff piece of card will usually do, but only if you are confident and the wasp is calm. If someone in the household is allergic or very anxious, keep away and let the wasp leave in its own time.
Check blinds, curtains and the folds of soft furnishings before you sit or lean, since a wasp may have settled there.
When the conservatory is a clue to a nest
Be alert if wasps keep appearing in the conservatory despite closed doors and tidy surfaces. A nest can sit in the roof space above a porch, in a cavity where the extension joins the house, under a gutter, in a nearby shed or in a hedge or tree next to the door. The workers fly to and from the nest, and some land in the glass room by mistake.
Watch the outside of the structure for a line of wasps entering a gap, for example where the frame meets the brick, or under a roof panel. A faint buzzing from the join between the old and new parts of the house can be another sign. You are likely to see more activity as the summer goes on, with numbers at their highest in August, when a nest can hold 2,000 to 10,000 or more wasps.
As with any nest, do not block the entrance, do not tap or poke at it, and do not stay close to watch.
Another sign is a nest in a nearby bush, tree or outbuilding with wasps visiting the glass room only in passing. Ask yourself whether the number of wasps outside is high compared with the number inside. A busy outdoor flight line suggests that the real issue is the nest, not the room.
