Why Are Wasps Flying Into Your Thorner Home? Common Causes and Solutions
Waiting for autumn to sort itself out is the usual mistake, because late-season wasps are often at their most intrusive just as the colony starts to wind down.
The mistake: assuming the problem ends with the summer
Many people tell themselves that wasps die off in autumn, so there is no point doing anything. It is partly true, since colonies do decline once the season turns. But the decline is slow, and the weeks in between can be the worst of the year for wasps at windows, in kitchens and around anything sweet.
Through the summer the workers are busy feeding a growing nest. As the season passes its peak in August, there is less to feed, and the workers start to look after themselves. They want sugar, and your jam sandwich, glass of cider and open bin are exactly what they are looking for. They also become irritable and quick to sting if you swat at them.
So the wait-and-see approach means living with the most intrusive phase. This guide sets out what to check and what to do while that phase lasts.
There is a further point about timing. In autumn the queens that will found next year’s colonies are produced, and the old workers gradually die. That does not mean the nest vanishes quickly, though. Until the cold weather arrives it can still be active, still protected by workers and still close to your door, so what you do in these weeks has a real effect on how comfortable your garden is.
What is different about late-season wasps
- They are more interested in sweet food and drink than in the protein they hunted earlier.
- They hover around fruit, bins, bottles and cans for long periods.
- They fly more erratically, so straying through an open window is more likely.
- Numbers can still be high because the nest has reached its largest size.
- Fallen apples and plums in gardens nearby add to the supply, and draw wasps toward the houses beside them.
In practical terms, this is the time of year when a nest you never noticed can suddenly announce itself, because its workers have started wandering far further and more boldly than before.
Checklist for a house under autumn pressure
- Keep doors and windows shut or screened during the warmest part of the day.
- Wash up straight after meals, and rinse out cans, bottles and jars before recycling them.
- Check outdoor tables, children’s cups and pets’ dishes for sticky residue.
- Close the bin lid fully and, if possible, stand the bin a few metres from the back door.
- Pick up windfall fruit from the lawn if you have a tree.
- Look under and around outdoor seating, where spilt drinks tend to collect.
- Note any place where you can see wasps repeatedly going in and out.
Do the first six for a few days and see whether the numbers fall. The seventh is the one that tells you whether you have a nest to deal with.
It is also worth keeping a small supply of practical tools within reach: a tea towel for guiding a wasp to a window, a lidded jug for drinks outdoors, and a mesh food cover for the table. They cost little and they let you carry on with ordinary life without waving your arms about, which is what tends to get people stung.
Telling food-seekers from nest traffic in September
Late in the year, the line between the two blurs, because even a nest far from the house sends sugar-hungry workers across a wide area. The test is whether wasps keep appearing after the attractions are gone and whether you can see a consistent flight line.
A food-seeker lands, feeds, and leaves in any direction. Nest traffic keeps returning to one hole, gap or crevice and moves in purposeful lines. If you can spot a small gap in the eaves, a hole in a bank or a hollow in a hedge base where wasps keep vanishing, you have a nest and the food check is secondary.
It is quite possible to have both a nest and a food draw, which is why tidy-up and treatment are best thought of as partners.
Another useful clue in September is the time of day. Food seekers turn up when you eat and drink, around lunchtime and tea time. Nest traffic carries on regardless, from mid-morning until the light fades. If you see wasps going to the same gap at a time when nobody has put out any food, that is the nest, not your picnic.
Why it is worth acting even when the season is ending
A nest that is still active in October is still capable of stinging when disturbed, and it may be sitting beside a door, a washing line or a play area that your family uses daily. Treating it removes the daily risk, whereas waiting leaves it in place for weeks.
Households with anyone who is allergic to stings have an additional reason not to wait. Tell us if that applies when you book, and keep that person away from the area. Anyone who develops swelling of the face, lips or throat, wheezing, dizziness or a widespread rash after a sting needs an urgent call to 999.
If you rent the property or manage it for someone else, who arranges the treatment depends on the tenancy agreement or the policy that applies, so check it or ask the owner. Whatever the answer, the earlier it is raised, the sooner the nest can be dealt with, and the less time everyone spends working around it.
In the meantime, remember that wasps cannot sting through a closed window. Keeping the glass shut in the busiest part of the day is a simple way to stay comfortable.
