Wasp Nests Under Roof Tiles – A Common Problem for Burley Homes
A nest under the tiles starts as a single queen in spring and ends as a crowded colony by August, which is why the timing of your call matters.
One queen in a dry gap
A householder notices a lone wasp slipping under a ridge tile one mild day in late April and thinks nothing of it. A couple of weeks later there are a few more, and by midsummer the same gap has a steady stream of traffic. The story is typical of a nest under a roof, and it explains why a problem that looked trivial in spring feels alarming in August.
It begins with a single queen who has spent winter sheltering somewhere and emerges when the weather warms. She looks for a dry, sheltered cavity, and the space beneath roof tiles suits her very well. She builds a small paper nest and rears the first workers herself.
It is easy to forget about a roof gap because nobody looks at the top of the house for months at a time. That is exactly why nests there grow unchecked.
The summer build-up
Once the first workers hatch, they take over building and feeding, and the queen stays inside laying eggs. From then on the colony grows rapidly. The exact pace depends on the weather and how mild the spring has been, so it varies from year to year, but the general pattern is steady through the summer.
- Late April to May: a queen starts a small nest. Activity at the gap is slight and easily missed.
- June and July: workers become more numerous and the traffic in and out of the roof becomes noticeable.
- August: the colony is at its peak. A nest can hold anywhere from 2,000 to 10,000 or more wasps.
A nest in Burley follows the same cycle as one anywhere else, and the busier the colony, the more likely wasps are to wander into gardens and houses.
Why earlier is easier
The price does not change with the season, so there is no financial reason to wait, but there are other reasons to act early. A small, young colony produces fewer wasps near the house, fewer stings at the washing line and fewer wasps exploring your loft or bedrooms. It also means you spend less time worried about the children playing outside.
If you suspect a nest in spring, do not wait for it to prove itself. Any consistent movement at one point on the roofline is enough to justify ringing. Early in the season it might be only a handful of wasps, but the same entrance will become a lot busier by summer.
A further reason to move early is peace of mind. A nest you know about and have booked is far easier to live with than one you hope will go away, and the summer holidays are a poor time to share the garden with a growing colony.
Signs of each stage on your roof
You can recognise where a nest is in its cycle from what you see on the outside, although only roughly. Treat the following as a rule of thumb and not a measurement.
In spring, a nest might show as a single wasp entering and leaving every minute or two. It is easy to wave off, and people often do. A little later, as workers emerge, the movement increases and you may spot several wasps arriving together. By midsummer the entrance looks like a small motorway, and wasps hover around it as they wait to land.
At the busiest point, you may also see wasps gathering on a nearby wall, feeding on weathered wood or chewing at the fascia. They are collecting fibre for the paper that builds the nest, and it is another sign of an established colony.
In every case, the safest way to observe is the same: from a few metres back, without a ladder, without a torch and without poking the entrance. Colonies get more defensive as they grow, so the larger the nest, the more important it is to keep your distance.
If you notice early signs, you have a real advantage. Ring us in May or June rather than in August, and the problem will be smaller and calmer to deal with.
Late summer behaviour
By late summer the workers become more irritable and more interested in sugary food and drink, which is why people notice them around picnics, bins and fallen fruit. A roof nest also becomes more obvious because of the volume of movement. If you see a thick line of wasps in the afternoon air or lots of them hovering by the eaves, the nest is probably well established.
Stay away from the roof edge, keep windows nearby closed, and resist any urge to deal with it yourself. The nest is hidden, access is awkward and the colony will defend itself.
Keep an eye on the same spot for the rest of the season. If wasps are still using the gap a few days after the visit, let us know, and we will talk it through with you.
Getting it treated
Our fixed price for a nest is £90, with no call-out charge, and £35 for each extra nest on the same property. The price is confirmed on the phone before the technician comes, and nothing is done unless you agree to it. The number to ring is 0113 347 0014, and the contact page also has an online booking form.
We are open seven days a week, offer same-day service, and work at homes and commercial premises. The technicians are trained and the work is fully insured. If you or someone in your home is allergic to wasp stings, tell us when booking so we can take it into account.
Once the nest has been treated, wait until the activity has stopped before you ask a roofer to repair the gap. Whether the empty nest can be taken down is something to raise with the technician when you book.
