Do Wasps Return to the Same Nest Every Year? A Guide for Rossington Gardens
Roof spaces and eaves are among the most common places for a wasp nest. Here is why last year's nest will not return and how to reduce the chance of a new one.
An empty nest in the roof space
You go up into the loft in the winter to fetch the decorations and find it: a grey paper nest fixed to a rafter, or tucked in the corner where the roof meets the wall. It was probably built over the summer and abandoned once the cold set in. It is quiet now, and you may well wonder whether it will be buzzing again in June.
It will not. Every wasp colony is annual. The workers die in autumn, the queen who began the nest has long since died too, and the structure is left behind. Next year's wasps start from nothing and build their own nest, even if it is a metre away from the old one.
If the nest is in a loft that you rarely visit, it may be worth a look each winter simply to know what is up there. Take a torch, tread only on joists or boards that will take your weight, and keep your head clear of the underside of the roof. Do not rush, and do not go alone if the access is awkward.
How new queens find the roof
The insects that matter for next year are the young queens that leave the nest at the end of the season. They spend the winter sheltered in a hidden spot, and in spring they come out and look for a site to begin a nest. From early April, depending on the weather, you may see a lone wasp flying close to the building, slowly examining the edges of the roof.
Anything that offers a sheltered opening can be of interest. Typical entry points to a roof space include:
- gaps behind or beneath fascia boards and soffits
- slipped, cracked or missing tiles
- holes where pipes or cables pass through the wall
- air bricks and vents with damaged covers
- spaces beside chimney flashing
She does not need a large hole. A gap that looks tiny from the ground can be perfectly adequate for a queen.
When to inspect and when to repair
The best time to look at the outside of your roof is in late autumn or winter, once the colony has died off and before the new queens start looking. At that stage, if you are sure nothing is living in the gaps, you can plan repairs without any risk of trapping live insects.
- Look from the ground with binoculars if you have them, working along the line of the eaves.
- Note any sagging boards, gaps and damaged vents.
- Ask a competent roofer or builder to carry out repairs rather than going up a ladder yourself.
- Choose the colder months for the work.
- Check again in March, before queens become active.
Safety on ladders and roofs is a real concern, and in Rossington as elsewhere the risk of a fall should be weighed against the benefit. Hiring someone who is properly equipped is often the sensible option.
Why not seal gaps in summer
It can be tempting to block a hole as soon as you see wasps using it. Please do not. Insects shut inside will search for another way out, and in a roof they may find one that leads into a bedroom, landing or the space behind a light fitting. The nest also continues to grow behind the barrier, and the wasps outside may become agitated as they circle the blocked entrance.
The right order of events is to have an active nest treated first, wait until the technician says the colony is finished, and only then close the gap. That way the repair keeps new queens out of the space rather than trapping the old colony in.
Noticing the signs indoors
If a nest is established in the loft or between floors, there may be clues inside the house. You might hear a gentle rustling or humming in the ceiling on a warm day, see wasps crawling on a window in an upstairs room, or spot a few insects around a light fitting. A small cluster of wasps indoors, in a room that is not near an obvious open window, suggests they have found their way in from inside the structure.
In that case, keep the room closed, keep family members and pets out, and avoid disturbing the ceiling. Do not push anything into a hole or hit the wall. Take note of when and where you saw the insects and tell the technician.
It also helps to know that a nest in a roof space does not always give itself away. The first sign may be a wasp or two in a room at the top of the house, or a dark stain where material has been chewed. Neither proves a nest, but both are worth a calm investigation from the outside.
Look at the outside wall beneath the suspect area on a warm afternoon. Steady traffic to one point under the eaves or at the edge of a tile will tell you where the entrance is, without any need to go into the loft.
Arranging treatment for an active nest
The Wasp Exterminator treats nests for a fixed £70 per nest, and any further nest at the same property is £25 extra. There is no call-out charge, we work seven days a week, and same-day service is offered. Our technician is fully insured and qualified, and works at homes and businesses alike.
The price is confirmed on the phone before the visit. In a difficult spot where special access equipment is needed, such as a high roof edge, the price might be more, and nothing goes ahead until you have agreed. Ring 07798 792 774, use the online booking form, or send a message through the contact page. After the treatment, ask whether the empty nest can be taken down so that you are not left with it in the roof.
If you are worried about getting up to the roof space, say so when you ring, and tell us how the loft is reached. It is far better for the technician to know about a narrow hatch or a high gable before arriving.
