Why Are Wasps Flying Into Your Diseworth Home? Common Causes and Solutions
Glass rooms and patio doors are warm, bright and often left ajar, which makes them a favourite route for wasps, though a stubborn problem there can also point to a nest close by.
Why a sunny glass room draws wasps in
A conservatory, orangery or set of patio doors catches the sun and traps heat. On a warm day it becomes the most comfortable room in the house, and often the one with a door standing open to the garden. Wasps are drawn to warmth, light and the odd drink or biscuit crumb, and they reach the glass because they are trying to get out as much as in.
Once a wasp is inside it flies towards the brightest area. In a glass room that is everywhere, so it bounces from pane to pane, unable to find the door it entered by. This is why a conservatory can seem full of wasps when there are really only a few, flying round and round.
Heat plays its own part. On a hot afternoon the air inside a conservatory can feel stuffy, so people throw open every door and window to cool it down. That is the moment a passing wasp is most likely to wander in. If you can, open vents and doors on the shaded side of the house instead, and use the sunny side only for short periods.
Seasonal timing matters, too. Wasps begin nests from late April depending on how mild the spring is, so early visitors in a conservatory can be queens looking for a spot to build. A queen exploring a roof void or a quiet corner behind a blind is worth removing gently into the garden before she settles.
Where they get in
Doors left open are the most obvious route, but glass rooms have many smaller ones too. Check each of the following:
- trickle vents and roof vents that open without a mesh
- the gap beneath a patio door where the rubber seal has worn
- a sliding door track packed with leaves and debris
- holes where a cable, pipe or aerial passes through
- slipped or missing sealant between the glass roof and its frame
- the junction where the conservatory meets the main house wall
Wasps find these routes by following air currents and scent. If a gap is big enough for you to see daylight through, assume it is big enough for a wasp.
Making the room less welcoming
Keep the doors shut when the room is not in use, and fit a fly-screen or magnetic mesh curtain to those you open regularly. Fine mesh can also be fixed across roof and trickle vents from inside, which gives you ventilation without visitors.
Take cups, glasses and plates back to the kitchen and wipe the tables, because a half-finished drink on a conservatory table in the sun will be found at once. Move potted plants that drip sugary sap or have fruit on them, and clear any fallen petals or ripe fruit from pots near the door.
A pale, plain blind drawn across the sunniest panes can reduce the dazzle that makes wasps panic against the glass.
A tidy-up of the floor is worth doing as well. Crumbs and drips in the carpet, rug or tiled corners attract ants and wasps alike, and a quick sweep each day cuts down the supply of food that keeps insects hanging around once they have found their way indoors.
If the room is used as a dining area, lay the table late and clear it quickly, and keep jugs of squash covered. Sweet smells hang in warm, still air for a long time.
Dealing with a wasp that is already in the room
A calm, simple approach works best. Open the door or the largest window as wide as it will go, and dim any lights inside. Stand away from the wasp and wait. It will usually find the exit within a few minutes.
A glass and a stiff card can be used to guide one that has settled on a pane, if you feel steady enough. Do not use a rolled newspaper against a window, because a wasp that survives the blow can fly straight at you. Keep children and pets out of the room until the insects have cleared.
If you are stung while clearing a room, wash the spot, remove the sting if you can see it and use a cold pack. Facial swelling, wheezing or a widespread rash needs a 999 call.
When a conservatory problem means a nest
If wasps keep arriving through the summer in spite of a closed, tidy room, look further out. Signs include a line of wasps flying to one point on the outside of the frame, wasps crawling out of the join between conservatory and house, or buzzing from the roof void above. A nest can be built in a cavity in the wall, under the eaves of the main house or in a nearby shrub, and the glass room just happens to be the nearest thing for the insects to explore.
In Diseworth or anywhere else, do not try to seal or block a suspect gap yourself. A colony that finds its exit closed will search for another, and your room may then be the closest one. Colonies grow all summer and can hold thousands of wasps by August, so it is better to act early.
