Do Wasps Return to the Same Nest Every Year? A Guide for Sewards End Gardens

A vehicle left standing in a yard or drive can become a nest site, and a quick routine in spring avoids a nasty surprise on the road.

A different kind of cavity

Cars, vans, caravans, horse boxes, trailers and agricultural machinery have many hollow spaces. If a vehicle stands unused for weeks, as many do in winter or between jobs, a queen may find a gap in the bodywork, a wheel arch or a cab and begin building.

Old nests are not reused. The wasps from last year are gone, and a vehicle that carried a nest last summer carries nothing now. But a vehicle that stays still in the same corner of a yard offers similar shelter to a shed.

Owners in Sewards End and elsewhere who use vehicles seasonally should include a quick check in the spring routine.

The same reasoning applies to vehicles at an agricultural or trade site, where a vehicle may stand for weeks in an otherwise busy yard and never be looked at.

Even a car parked on a drive can pick up a queen, so the advice applies to everyone, not just those with a farm or a yard.

Where to look

Walk around the vehicle in daylight. Look at the wheel arches, under the bumpers, around the door seals and inside the cab. For vans and trailers, check the corners of the load area and any tarpaulins or covers.

• Wheel arches and the underside of the bodywork.
• Gaps between panels and around lights.
• Folded covers and tarpaulins.
• Air intakes and vents.
• Stowage boxes, toolboxes and cab storage.

Do not put your hand into dark gaps without looking first.

Spring is the most important time. A vehicle that was last used in October and is started up again in April may have been a winter shelter for a sleeping queen. She is not dangerous in that state, but she wakes when the engine warms, and she may be in the cab with you.

Open doors and the bonnet before you set off, look around the engine bay and under the seats, and give the vehicle a minute to air before you drive.

If wasps are inside

Do not drive off with a nest in the vehicle. Stop, switch off the engine, open the doors from a distance if you can, and move away. Wasps in a moving vehicle are dangerous because the driver may panic. If wasps appear while you are driving, pull over calmly, get out and leave the doors open.

If you suspect a nest in the vehicle, do not tap, shake or start it repeatedly. Keep people and pets away, and arrange treatment.

Fit a mesh cover over air intakes during storage if the manufacturer allows it. Parked machines such as tractors, mowers, quad bikes and hedge cutters can also contain nests in their covers or seats. Check them as you would a vehicle.

Wear gloves and long sleeves when you open up stored equipment.

Caravans, horse boxes and trailers

These structures are often parked for long periods in a corner of a field or drive. They have roofs, eaves, vents and awning channels, all of which can shelter a queen. Check them in spring, and clear any debris from channels and corners.

Close vents with mesh if the manufacturer allows it, and keep awnings dry and stored indoors.

If you keep a caravan on a pitch or drive, ask whoever helps with maintenance to include a wasp check in their rounds.

Awning channels, vents and window frames are the most likely places for a queen to settle, and a brush along the channel in spring is a simple precaution.

If you tow a trailer or van with a covered load, look under the cover before you leave and again at your destination.

Shake out loose sheets in the open air, standing back.

Do the same when you return the vehicle to its parking spot at the end of the season.

Prevention and storage

Park vehicles clear of hedges and walls where possible. Keep covers tight and in good repair. Avoid leaving food waste or sweet drinks inside. Clear leaf litter from air intakes, and do a walk-round every time you use the vehicle after a long gap.

For commercial fleets, add a visual check to the driver’s daily routine in spring and summer.

Keep cabs free of food wrappers and drink cans, which attract wasps in summer. A closed bin in the yard and a quick tidy at the end of each shift make a difference.

If a vehicle belongs to your business, record any wasp events as you would other incidents.

When a vehicle goes into long storage, give the interior a thorough clean, empty all compartments and leave the doors slightly ajar, if it is safely indoors, to stop stale air collecting. Keep it away from bushes and fences if you can.

Check windscreen wipers, mirrors and the area under the bonnet in April, since queens sometimes shelter in the folds of old covers.

Write the date of your spring check on a card in the cab.
