Found a Wasp Nest in Your Loft in Stanningley? Here's What to Do
A loft nest found in late September or October may still be active; this guide helps you judge, and says what to do before the cold sets in.
Late-season nests are still worth taking seriously
If you find or hear a wasp nest in your loft in September or October, it may still be active. The colony peaks in August, and then declines, but workers stay busy for some time afterwards, and they often become more irritable and more interested in sugary food as the season ends. The safe course is to treat it as live until a technician tells you otherwise.
Cold nights will eventually end the colony, with only young queens surviving to hibernate elsewhere. But that can be weeks away, and a warm autumn stretches the season. The loft, warmed by the house below, may keep a colony going longer than a nest outdoors.
So while there is no need to panic, there is also no good reason to wait for a frost.
Keep in mind that the age of the nest tells you very little about its safety. A large, mature nest in October is, if anything, a bigger structure than the one that was there in June, and it may still hold a lot of wasps.
Is it still active?
You can judge a good deal from the ground and from the rooms beneath the loft.
- Active: wasps still flying to and from a gap on mild days, a hum overhead, wasps appearing indoors or around the bin and kitchen window.
- Fading: fewer wasps, slow and clumsy ones on the ground or at windows, and little traffic at the entrance.
- Finished: no activity at all on several warm afternoons, no sound, and no wasps around the home.
Because a nest can look quiet on a cold or wet day, do not decide from a single look. Judge it on a mild, dry afternoon, and even then keep out of the loft. If you are not sure, phone and describe what you have noticed.
A useful rule is to look at the ground beneath the entrance as well. Dead wasps there suggest the colony is failing, while clean ground and busy traffic suggest it is still going. Neither is a reason to approach the entrance.
Why autumn wasps seem worse
Householders often feel autumn wasps are more aggressive, and there is a reason for that. Late in the season the workers no longer have grubs to feed, which means they lose a source of sugar and go looking for it elsewhere. They turn to fruit, drinks, bins and the sweet things on your kitchen table. The result is more wasps in more places than you saw in summer, and more chance of a sting.
That makes sense of the pattern many people notice, with wasps at the back door in September that they hardly saw in June. If you have a nest in the loft, the wasps indoors and on the patio are probably from it.
Keep food covered, check drinks before sipping, rinse cans and bottles before putting them in the recycling and keep bin lids closed.
Rubbish bins, compost caddies and recycling boxes are particular magnets. If you can, move them away from the back door for a few days and rinse out any containers that held sugary drinks or beer. The less there is for wasps to find, the fewer will come to your door.
What to do now
The steps are the same as at any other time of year.
- Shut the hatch and keep out of the loft.
- Leave the entrance open, because blocking it sends wasps into the house.
- Do not use an aerosol on, tap or poke at the ceiling.
- Open a window in any room where a wasp has strayed so it can leave.
- Phone to arrange a treatment rather than waiting for the cold.
Anyone stung should have the area washed, the sting removed if it shows, and a cold pack held against it. Call 999 for swelling of the face, lips or throat, wheezing or trouble breathing, dizziness or a widespread rash. If anyone at home is allergic, tell us when you book.
If the weather turns cold, resist the urge to assume the problem has gone. A heated house can keep wasps in the loft active on a mild day long after the garden has gone quiet.
Booking and the visit
A wasp nest treatment is a fixed £90, confirmed on the phone before the technician arrives. There is no call-out charge, and nothing is done without your agreement. If a second nest turns up at the same address, that one is £35. Our technicians are trained and the work is fully insured, for homes and commercial premises alike.
Tell us where the wasps are entering and how the hatch is reached. The technician will carry out the treatment and can tell you whether the empty nest can be taken down. We cover Stanningley and the surrounding area, are open seven days a week, and offer same-day service.
If you are weighing up whether to bother this late in the year, remember that the visit is a fixed £90 and the nest, left alone, can still produce wasps in your rooms for as long as the weather stays mild.
Clearing up and looking ahead to spring
Afterwards, vacuum or sweep up dead wasps near the hatch, wearing gloves. Leave the nest until the technician advises you.
The winter is a good time to have the gap repaired, because there are no queens searching and no colony to disturb. Ask a builder or roofer to close the entry point, and check the roofline again next April. To book, phone 0113 347 0014 or use the form on the contact page.
