Wasp Nests Under Roof Tiles – A Common Problem for Darenth Homes
By August a roof nest is at its busiest, and wasps behave differently. This guide covers the late-season picture and why it pays to book as soon as you notice a problem.
How a roof colony changes through the year
In late April or May a single wasp starts the nest alone. A few weeks later the first workers appear and begin to take over the building and the feeding. From then on the colony grows steadily, and by August it is at its peak, with anything from 2,000 to 10,000 or more wasps.
A nest tucked under the tiles can pass most of June without anyone noticing. The wasps are few, and they go about their work quietly. By the end of July, though, the numbers have grown enough that you start to see the traffic.
Residents of Darenth who first notice wasps in August are often seeing a nest that has been growing for three months.
The practical lesson is that wasps in August are not a sudden event. They are the result of a slow build-up, which is why the nest can seem to appear from nowhere.
Why late summer feels worse
Several things combine in the last weeks of the season. The colony is at its largest. Wasps spend more time away from the nest looking for sugar, so they bother outdoor meals, bins and drinks. And the roof entrance can be busy from mid-morning until dusk.
- More wasps at windows and doors, as workers search for sweet food.
- Louder buzzing in the roof or at the wall.
- Wasps that seem more irritable around the entry point and the garden.
- Wasps in the kitchen or on the patio, even when the nest is out of sight.
It is easy to blame the garden for all this. In many cases the cause is a nest in the roof, and no amount of trapping or clearing up the garden will help.
Wasps looking for sugar are also attracted to open drinks, ice cream, fruit and rubbish. In late summer a picnic table near the nest entrance can become a hazard within moments.
Reading the roof when everything is busy
Late-season traffic actually makes the entrance easier to find. Stand well back on a warm afternoon and watch the roofline. The stream of wasps to and from one spot should be easy to see, even from the pavement.
Note the position, and keep your distance. At this time of year the entrance is heavily defended, and walking close or standing under it can draw a response very quickly.
Resist the urge to climb up, even to look. A ladder against the gutter would put you at the entrance of a nest at its largest. The job belongs to a technician with the right equipment.
If you have a second possible entrance, such as a gap at the other end of the same roofline, note that too. At the peak of the season it is not unusual for a large nest to use more than one exit.
Do not leave it until the weather turns
There is an old idea that the cold will do the job, and that a nest can be left to die off in the autumn. It is true that colonies decline late in the year, but that can take weeks, during which the nest remains active and the wasps are at their most irritable.
Meanwhile, the household has to live with the nest. Windows stay shut, children do not play in the garden, and a stray wasp can find its way indoors. Treating the nest as soon as it is found ends all of that.
It is also not wise to seal the gap during these weeks. A blocked entrance in August means thousands of wasps looking for another exit, which can easily be through a ceiling.
Think of the weeks between mid-August and the first cold nights as the most awkward of the lot: the nest is still large, but the wasps are less purposeful and more likely to wander into people's space.
Staying safe in the meantime
Keep food and sweet drinks covered outdoors, put lids on bins, and clear up fallen fruit. These steps will not remove the nest, but they reduce the number of wasps around the garden.
If someone is stung, wash the area, remove the sting if you can see it and apply a cold pack. Swelling of the face, lips or throat, wheezing, trouble breathing, dizziness or a widespread rash require a 999 call. People with a known allergy should speak to their GP and tell the office so that the booking can be prioritised.
Pets can be stung as well. Keep dogs and cats away from the wall below the entry, and bring their bowls indoors, since wasps are drawn to food left outside.
The price, the booking and the end of the season
A nest is treated at a fixed £120 per nest, with another nest on the same property at £60 extra and no call-out charge. The price is the same in late summer as at any other time, and no extra is added for the busy period. One visit is guaranteed.
The business is open seven days a week and offers same-day service, with evening and weekend appointments too. You can call 01622 410 019 or use the online form, which also covers emergencies out of hours. Domestic and commercial customers are both treated.
After the treatment, some wasps will keep returning to the old site for a short time. When the autumn arrives, have the roof gap repaired so that next spring's wasps find no way in. You can ask about removing the empty nest when you book.
An autumn repair also gives you peace of mind through the winter, since you will not have to think about it again until the following April.
