Why Are Wasps Flying Into Your Harpenden Home? Common Causes and Solutions
Sweet drinks, open patio doors and half-finished plates all draw wasps indoors. A few small changes at mealtimes can stop most visits before they start.
Why the kitchen gets the most visitors
If wasps are turning up in your home, look first at where food and drink are handled. Kitchens, dining areas and the doorway between house and garden are where scents leave the building. A foraging wasp follows those scents upwind and finds the opening.
Adult wasps feed on sugars, which is why fizzy drinks, squash, wine, ice lollies and jam are so attractive in summer. The workers also collect protein to feed the grubs in the nest, so meat on a barbecue plate or an open pet food tin is just as appealing.
This means the cause is often at your own table rather than at a nest. That is good news, because you can change it today.
Keeping a jug or glass lid on the worktop costs almost nothing and makes an immediate difference.
A walk-through of a typical summer lunch
Imagine the back door propped open, a jug of lemonade on the worktop, plates stacked by the sink and a bin bag waiting to go out. Each item is a signal. The wasp enters through the open door, circles the jug, lands on a plate and then drifts into the next room as it searches for the way back to daylight.
Now picture the same lunch with a few adjustments:
- Drinks covered with a lid or kept in a fridge until needed.
- Plates rinsed and scraped at once, with the scraps going into a lidded bin.
- A fly screen or bead curtain across the open door.
- The bin bag taken outside to a closed bin, not left in the porch.
The wasp has far less to follow, and far fewer reach the room at all.
Telling a mealtime visitor from a nest problem
Mealtime visitors come and go with the meal. They show up when food is out and fade away once it is cleared. If wasps turn up when nothing sweet is on show, at the bedroom window at breakfast time or in an empty hallway, something other than food is drawing them.
Watch from a safe distance to see whether they take a single line to and from the same spot on an outside wall or the eaves. A repeated line means a nest sits at the end of it. Wasps that approach randomly, from different directions, are most likely foraging independently.
Resist the urge to follow the line right up to the gap. Standing close to a live entrance is the quickest way to get stung.
Barbecues, picnics and the garden table
Outdoor meals deserve their own thought, because the wasps you attract there often follow you indoors. A table laden with ice cream, fruit and cider is a magnet from late July onwards, when natural food becomes scarcer for the colony.
- Serve food in small portions and bring the rest out only when needed.
- Use cups with lids or keep a hand over open cans, since wasps crawl inside unnoticed.
- Place a small dish of something sweet, such as a little jam on a plate, a few metres from where you sit, to draw them away from the table.
- Clear the table fully before going indoors, including sticky children’s cups.
A wasp that has fed at your table will remember the spot and return the next day. Cleaning thoroughly breaks that habit within a few days, as long as no one is leaving sugar out.
Small gaps, children and pets
Many homes have openings that are easy to overlook. A trickle vent left open, a cat flap, a gap under a back door or a window with a loose seal can all let a wasp through. Letting air in on a hot day is natural, but a mesh screen over the opening keeps the air and loses the insects.
Check also for tears in existing mesh. Wasps can squeeze through a surprisingly small hole, and once one has found it, others tend to follow the same scent trail.
If you find a wasp has built up a habit of using a particular gap, look outside for the reason. A nest in a wall cavity or soffit can send workers into the house through any crack that leads inwards.
Young children are stung most often because they grab at a wasp or run away from it. Teaching them to stay still and walk calmly away is more effective than flapping. Keep pet bowls indoors and rinse them after each meal.
If a sting happens, wash the area with soap and water, take the sting out if you can see it, and hold a cold pack against the skin. Call 999 if there is swelling of the face, lips or throat, a wheeze or difficulty breathing, dizziness or a spreading rash. Anyone with a known allergy should talk to their GP about what to keep at hand.
