Do Wasps Return to the Same Nest Every Year? A Guide for Kelvedon Hatch Gardens

Under the felt and above the rafters, a shed roof offers a sheltered pocket, and a late-winter repair can remove it before spring.

What a shed roof offers

A garden shed is a simple box, but the roof makes it a good nesting site. There is a space between the roof covering and the boards, sometimes a little gap at the eaves, and often a corner where the felt has lifted and the timber is soft. Inside, the rafters are dry and sheltered from every draught.

If a nest hung from the underside of your shed roof last year, it is finished. The colony died when the cold came, and the next generation will not use that shell. Each spring, fresh queens look for fresh sites, and a shed is an easy target.

Gardeners in Kelvedon Hatch who found a nest in the shed in summer often want to know whether to expect the same thing again. The honest answer is that it is possible, which is why a roof repair in winter is worth doing.

Shed roofs are usually the least maintained part of a garden. Felt is cheap to lay and easy to forget, so by the time a roof leaks or sags, there may already be a handy gap for an insect.

Signs that the roof is letting wasps in

The felt on a shed roof splits with age and frost. Edges lift, nails work loose, and the gap between the roof and the walls opens. Even a gap the width of a pencil will do. Inside the shed, look up on a bright day and see whether any daylight is showing through the roof.

• Light through the roof boards or around the eaves.
• Staining or damp marks on the underside of the roof.
• Fine wood-like flecks on the floor or on stored items.
• Gaps where the door frame has warped away from the wall.

Any of these is a possible entry route. Note them before you decide what repair is needed.

Look at the roof from outside as well, from a stable position on the ground. Curling edges, bubbles under the felt, missing ridge pieces and cracked bargeboards are all weak points. If the shed is large, check the lean-to or porch section as well, since that is often built less tightly.

Make a note of every spot you find and photograph them. A simple list lets you plan one repair session instead of several small ones.

Repair work in the cold months

Replacing felt or fitting a new roof sheet is a manageable job for a competent DIYer on a dry winter day, and a handyman can do it quickly. Seal the edges well, nail down loose battens and cover joints properly. Use a stable ladder and have someone hold it. Falls from shed roofs are far more common than wasp stings.

Check the base and the floor too. Sheds raised on blocks can have gaps below the floor, which a queen may use. Ensure that any ventilation is still adequate to prevent damp, and use fine mesh over vent openings.

If you rent the garden and the shed belongs to the landlord, your tenancy agreement will say who is responsible, so check before starting work.

While you have the roof off, look at the inside of the boards for old nest material. Small flecks of grey paper stuck to the timber show where a nest once hung. Brush these away with gloved hands, and wipe over the boards so you can tell next spring whether anything new has appeared.

New felt should overlap generously and be fixed at the edges. Trim the overhang tidily, and avoid leaving loose flaps that a wasp could squeeze beneath.

The inside of the shed

Clutter hides things. Stacks of seed trays, sacks of compost, folded tarpaulins and old cushions give a queen somewhere to explore. Keep items off the roof line, on shelves away from the corners, and store soft materials in lidded boxes.

In April, open the door and stand quietly for a moment. Look up at the roof line, then at the corners. A queen investigating the shed is often quite slow and noticeable, flying in circles near the ceiling. A grey, papery starter nest the size of a walnut will be visible if you look.

Check again each week through May, since the nest grows quickly after the first workers appear.

Garden tools such as hoses, nets and fleece should be rolled up and stored in a container, not hung from nails where the folds create hiding places. A shed that is tidy and well lit is much easier to inspect.

If the shed is also a workshop or an office, the occasional visitor will be more aware of changes, so tell regular users what to look out for.

Dealing with an old nest

If you find last year’s nest, make sure it is dead by watching for activity and checking that it is dry and brittle. Then put on gloves, lift it into a bag and bin it. Avoid breaking it in an enclosed space, since the fragments are fine and can irritate the nose.

You can ask the technician when booking a live nest treatment whether an empty nest can also be taken down.

Remember that a nest in a roof can be larger than it looks from inside, because much of it may sit in the space above the boards.
