Found a Wasp Nest in Your Loft in Upper Harbledown? Here's What to Do
Knowing what a wasp colony does in each part of the year makes it far easier to spot a loft nest early and decide when to call.
Spring: the quiet start
The year begins before most people are thinking about wasps. From late April, depending on the weather, a single insect starts a small nest, often in a loft, an eaves gap, a wall cavity or a hole in the ground. At this stage there is almost nothing to see. A warm spell can bring the start forward, while a cold one delays it.
If you can, glance at the roofline in May. You are looking for one or two wasps repeatedly flying into the same gap. That small sign is the earliest warning you are likely to get.
Weather shapes all of this. A wet, cold spring tends to slow nests, while a warm, dry one speeds them up. You cannot predict the pattern in advance, so it is more useful to watch what is happening than to rely on a calendar.
Early summer: workers take over
By June the first workers have hatched, and they take over building and feeding. The nest grows steadily, and traffic at the entrance picks up. You may begin to hear a faint rustle if the nest is above a bedroom.
This is a good moment to book if you have seen a flight line. The colony is still small, the nest is easy to treat and the household has not yet been troubled. The price is a fixed £120 per nest, so there is no financial reason to wait.
One simple routine is to choose a regular day, such as the first Sunday of the month, to walk round the outside of the house from May to September. Look at the eaves, soffits and corners, and listen for a hum. It takes five minutes and does not involve going near any gap.
High summer: the August peak
The colony peaks in August. A nest can hold between 2,000 and 10,000 wasps or more, and the roof space becomes busy. This is when most people notice a problem: wasps in the house, a hum in the ceiling and a constant stream at the roof edge.
At this size, the nest is at its most defensive. Keep clear of the hatch, avoid the roofline and do not attempt any DIY solution. A professional visit is straightforward, but the nest must not be disturbed beforehand.
If anything is amiss, make a note, take a photograph from a distance and call. A short phone conversation is often enough for the technician to say whether it sounds like a nest and how soon to visit.
Autumn: a colony in decline
In September and October the colony begins to break up. Workers become less organised and wander further, drawn to sugar, fallen fruit and warm rooms. They can seem more irritable at this stage, and stings are common.
By November the nest is usually finished, although a mild spell can keep it going. If wasps are still active, treatment is worthwhile. If the loft is quiet, the nest may be empty, and you can ask the technician whether it should be taken down.
At this time of year, empty nests are also easier to examine. Ask at booking whether the nest can be taken down, so that it does not sit in the loft through winter sitting unused.
Winter: the empty shell
Through winter the old nest sits unused. It is never reused, and a new colony starts from scratch the next spring. Winter is a good time to check the loft from the hatch, with the nest inactive, and arrange any repair work on the roof edge.
If you find an old nest while tidying, do not assume it is dead. Leave it alone and ask. A hatch that sits snugly in its frame and sound fascia boards are worth a look from a builder while the weather is cold.
Plan any loft work, such as insulation or boarding, for the cooler months, when no colony is active. A tradesperson will thank you for it.
A month-by-month view also helps with practical planning. If you want to have the loft boarded, insulated or rewired, schedule it for winter, when nothing is nesting, and ask the tradesperson to check the roof edge for gaps before starting. If you need to use the loft for storage in summer, keep visits short, quiet and rare.
It is sensible to keep the number of the pest control service you trust somewhere easy to find from the start of spring. When you need it, you do not want to search.
Above all, the pattern is reassuring. Nests are seasonal. They start small, peak in August and fade in autumn. Knowing that, you can plan calmly rather than reacting to every wasp.

A mild winter may let a few wasps survive longer than expected, so if you see activity in December, mention it when you call.
Each month brings a small, sensible task. In April, check the hatch and tidy the loft. In May and June, look at the roofline from the garden. In July and August, keep away from the loft and respond quickly to wasps indoors. In September and October, expect more wandering wasps and keep food covered. In winter, arrange repairs. A calendar reminder on your phone for each is enough.
