Do Wasps Return to the Same Nest Every Year? A Guide for Chatham Gardens
A shed or garage that held a nest one summer is likely to look just as inviting next year, so the useful job is to make sure it is no longer easy to get into.
Outbuildings are popular for a reason
Sheds, garages and lean-to stores have a lot in common with the places wasps naturally build. They are dry, they are quiet for most of the year and they have corners where nobody looks. Add a door that does not quite close and a window with a broken pane, and you have an ideal nursery.
If you are in Chatham, one of the Medway Towns, or anywhere else, the story is the same. A colony builds in an outbuilding in spring, grows through the summer, and is gone by late autumn. The paper nest is left on a beam or against a roof panel, and the owner discovers it when they next go in.
It is not reused. The next nest, if there is one, will be a new one, begun by a different queen.
It is worth noting that outbuildings are used less often than the house, so a nest can develop for weeks without anyone noticing. Many sheds are only opened at weekends, and a colony that began in May can be sizeable by the time anyone looks.
The queen’s view of your garage
Think about what a queen sees on a spring morning. She is looking for a dark, dry cavity, and she can crawl through a very small opening. A gap under an up-and-over door, a missing vent cover, a hole where a cable enters and a crack in a roof panel are all invitations.
Stored items add to the appeal. Cardboard boxes, old curtains, rolled carpet and piles of newspaper provide corners and hollows, and a half-open sack in the corner is a ready-made hiding place.
She does not know about last year’s occupants. She only judges the site in front of her. If the site has improved since, it may even look better than before.
Light matters too. Dim corners that stay dark all day are more attractive than corners that get a stream of daylight through a window, so a tidy, brighter shed has a slight advantage even before you fix the gaps.
An autumn clear-out checklist
When the weather is cold and the old nest is plainly empty, it is a good moment to tackle the outbuilding.
- Take out the old nest, using gloves, and put it in a sealed bag.
- Empty any boxes and sacks that sat near it, and shake them out outside.
- Check the roof lining and the joins between wall and roof for daylight gaps.
- Look at the door seals, and fit a brush strip along the bottom if needed.
- Mend broken glass and fit mesh over any vents.
- Move stored materials onto shelves, off the floor and away from walls.
The result is a shed that looks tidier and is far less appealing to a queen.
Keep the old nest as long as you need to for reference, bagged and stored outside, and decide later whether to bin it. Otherwise, bin it straight away and note the position in your diary so that you remember where to look in April.
Keeping it closed over the warm months
Even the best repairs can be undone by a door left open all summer. From late April, try to keep the outbuilding closed when you are not using it, and look in once a week.
A quick glance is enough. Check the corners of the roof and the upper parts of the walls, and watch for a wasp that keeps appearing near the same spot. If you hear a steady buzzing that you cannot explain, do not go in to find out. Wasps in a confined space can be defensive.
If your shed has a window that you like to leave open for airflow, fit a fine mesh across it. This lets the air through and keeps out most flying insects, including queens in search of a nest site.
Be aware that a nest in an outbuilding can sit right beside a door that you use every day. Look up at the lintel and the top corners before you reach in for the key or a tool, and keep the habit through summer.
If a nest has started
A small nest in a shed in May is a better thing to find than a large one in August. It is still a live colony, though, and the entrance should be left alone. Close the door, keep children and pets away and put a note on it so that others in the household do not open it unaware.
If someone is stung, wash the area, remove the sting if visible and use a cold pack. Swelling of the face, lips or throat, wheezing, dizziness or a widespread rash call for 999.
The same applies to garages with up-and-over doors, where the top corners of the frame are often a weak point.
Warn visitors and tradespeople too, because they are the people most likely to open an unfamiliar door. A short note taped at eye level is enough.
Booking us in
A treatment is a fixed £120 per nest, and each additional nest on the same property is £60 extra. No call-out charge is made, and the price does not change by location or time of day. The technicians are fully insured and qualified, and they work in domestic and commercial settings in Chatham and the neighbouring towns.
Ring 01622 410 019 or use the online booking form at /contact-us/. We open seven days a week, offer same-day service where we can, and have evening and weekend appointments. Ask the technician at booking whether the empty nest can be taken down at the same visit.
Please do not rely on a quick repair done in a rush at the height of summer. Repairs while a colony is active can trap wasps and send them elsewhere in the building.
