Wasp Nests Under Roof Tiles – A Common Problem for Potton Island Homes

A nest discovered in September or October may seem too late to bother with, but wasps still in the roof can sting and still find ways indoors.

The late discovery

It is not unusual to find a roof nest late in the year. Trees have lost leaves, you can see the roofline better, or the wasps simply become more noticeable as the colony shifts its behaviour. The thought that follows is often the same: it will be over soon, so is it worth doing anything?

That is a fair question, and the answer is mostly yes if the wasps are still active. A colony that is flying in and out of the roof is still capable of stinging, and its members are drawn to sweet things, bins and open windows.

It is also true that people simply become more aware of wasps at this time of year. The garden is less busy with leaves and flowers, and the few insects remaining seem more numerous. That perception is not always accurate, so look at the roof edge, not the garden, to judge what is really happening.

Another reason for a late discovery is that a nest hidden in the roof is only noticed once wasps start looking for a way into the house. The first you know of it may be a wasp at a bedroom window in October, which is a sign that the entrance is busier than you thought.

What changes as the season turns

After the August peak, a colony gradually runs down. Wasps become less organised, and the number around the nest falls over time. What does not change quickly is the behaviour of the wasps that remain. Late in the year they are often more persistent around food and drink, and people are stung while drinking from cans or eating outside.

For a roof nest, this means two things. The risk of entering the house through gaps continues as long as the colony is active, and the nest does not disappear on a set date. Weather affects how long it lasts, and you cannot know when it will end.

Cooler mornings slow the wasps, and some days they hardly appear. Do not let a quiet morning persuade you the nest is finished. A mild afternoon can bring the colony back to full activity within a few hours.

Remember too that a mild spell can wake the nest. Wasps respond to warmth, so a bright October afternoon can bring a sudden burst of activity that surprises people who thought the colony had finished.

Questions to ask yourself

A short list helps you decide whether to book.

• Are wasps still flying steadily in and out of the same gap?
• Are any getting indoors, or showing up at windows?
• Does anyone in the household have an allergy to stings?
• Do children or pets use the garden near the entrance?
• Are you planning roof work, scaffolding or gutter cleaning in the coming weeks?

A yes to any of these is a good reason to arrange treatment. If the nest appears to be silent, you can simply keep your distance and watch. If in doubt, ring and describe what you see.

If the answer to most of those questions is no, there is no harm in watching from a distance for a few more days. Just remember that watching means standing well back, not approaching the roof.

What not to do now

Even with fewer wasps, the same warnings apply. Do not climb up to look, do not block the gap, and do not disturb the roof edge. A nest that seems quiet can still react strongly to disturbance. Sealing an entrance in autumn, when the colony is still alive, can still lead wasps toward the inside of the house.

If you want to repair the roof, do it after the nest has been dealt with and is no longer active.

A further reason not to wait is practical. If you plan to have gutters cleaned or a roofer in for some autumn maintenance, anyone working near the nest will be at risk. Tell them about the wasps before they start.

Equally, there is no need to rush into repairs. A rushed repair on a wet autumn day can trap live wasps inside, so it is best to wait for confirmation that the nest is inactive.

Booking and price

The treatment of a wasp nest is a fixed £90 per nest, with one visit guaranteed, and an additional nest on the same property is £35 extra. The price does not depend on the time of year or the position of the nest.

When you ring, mention how long you believe the nest has been active and how busy it is today, so that the business can advise you.

Setting up for next spring

Once the nest is no longer active, the autumn is a good time for a roof check. Ask a roofer to look for slipped tiles, gaps at the eaves and loose boards. A tidy roof edge gives next year's wasps fewer places to start.

You can also ask the technician whether the empty nest can be taken down. Fixing these things now means the roof is ready when the wasps begin looking again in late April.

Write the date of treatment in your diary. If you spot wasps entering the roof next April or May, you will know straight away that it needs another look.
