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

Back porches and utility rooms see plenty of traffic and plenty of smells, and they are often where the first wasp is noticed.

The overlooked entrances

Front and back doors get most of the attention, but the side door, the porch and the utility room often matter more. They are the places where coats and boots are left, washing is dried, bins are carried through and pets come and go. They also tend to have the least secure seals, with old door brushes and gaps under the threshold.

A porch is warm in the sun, sheltered from wind and often has a small window. For a wasp that has strayed in with a gust, it is a pleasant place to stop. It may linger there for hours before moving into the house.

Utility rooms bring another factor: the washing machine and tumble dryer vent. A dryer outlet that is poorly covered is a direct line from the outside to the room.

Look at how the space is used on a typical day. If the back door opens twelve times between breakfast and bedtime, the porch is effectively a revolving door for insects. Smaller changes, such as shutting the inner door before opening the outer one, remove a lot of the risk.

What attracts wasps there

Look at the contents of these spaces with fresh eyes:

• Pet food and water bowls kept by the back door.
• Recycling bins and food caddies brought indoors.
• Fruit and vegetable boxes stored on the floor.
• Bags of shopping left in a warm porch.
• Boots, bags and wet coats that smell of the garden.
• Sticky bottles of cleaning products or juice stored on shelves.

A few changes make a big difference. Store items in sealed containers, clear the floor, and put the bin outside as soon as it is full.

Drying racks and airers also need thought. Damp laundry on a rack near an open window holds warmth and moisture, and a wasp that lands on a towel can be carried into the house without anyone noticing. Shake items out and look at them before folding.

Sticky floors in a utility room, from spilt washing liquid or drink, attract insects too. A damp mop once a week in summer is a small job that pays off.

Sealing the weak points

Check the threshold and the door edges for light. A line of daylight under the door is a gap for insects. Fit a brush strip or draught excluder along the bottom, and replace worn rubber seals on the sides.

Look at the dryer vent and make sure its flap closes properly. Fit a mesh cover if the design allows. Look also at the letterbox, cat flap and any ventilation grille in the wall.

Do not seal any gap in which wasps are seen entering or leaving, because that would suggest a nest, and blocking it is not safe.

Stored paint tins, garden products and dirty pots in a utility room may carry sweet or yeasty residue as well. Wipe the outsides of containers and keep lids tight. A shelf of half-empty squash bottles is a very good way to bring wasps into the house.

When the porch is the first sign

Sometimes wasps in a porch are the first symptom of a nest in the wall, the roof or the garden. If they keep appearing there, try to work out why. Watch the porch roof and the walls from outside, and see whether wasps are going into the brickwork, the soffit or a vent.

A nest in a wall cavity next to a porch can send wasps through the plaster, and you might notice them coming from the corner of the ceiling or behind a coat rack. Keep a safe distance and do not poke or prise anything open.

If you have a conservatory or lean-to joined to the porch, the same checks apply to the joint between the structures. Such joints often have a gap behind the trim, and gaps behind trim are among the most common nest sites on the outside of a house.

If wasps are coming through from the wall above the door, close the inner door and treat the porch as a separate zone until the nest has been dealt with. A rolled towel along the inner door makes a surprisingly effective barrier.

Dealing with wasps already inside

If wasps are in the porch or utility room, open the outer door and the nearest window, and close the inner door so they cannot move into the rest of the house. Leave them alone for a while. Most will leave towards the light.

If numbers do not fall, call for help. Do not use the room for drying clothes or storing food until the issue is resolved.

If the wasps are numerous, do not go in and out repeatedly. Make one trip for what you need, and keep other doors closed.

Make sure that a family member is aware of the situation before they come home with arms full of shopping, since opening the door with bags in both hands leaves no way to react if a wasp flies out.
