Do Wasps Return to the Same Nest Every Year? A Guide for Arlesey Gardens
Underground nests leave no visible shell to remove, so the questions are about holes, soil and what to watch for when the weather warms.
Ground nests leave little behind
Most people picture a wasp nest as a grey ball hanging from a rafter, but many wasps nest underground. A queen in spring may take over an old burrow, a gap under a paving slab or a crack in a bank, and the colony digs out chambers beneath the surface. In summer the only sign is a small hole with wasps streaming in and out. When autumn comes the colony dies, and the chamber is left empty and often collapses or fills with soil. There is no shell to find, which is why people with ground nests tend to ask whether the wasps will simply return to the same hole. They will not reoccupy it as a nest. They start afresh, and may or may not choose the same area.
Ground nests can also go unnoticed because they sit among long grass, under shrubs or along the foot of a fence. A householder may walk past the same hole several times a day without seeing it, until a few wasps begin to hover over it. That is usually the moment people realise there is a colony beneath their feet.
Why the same patch of ground gets chosen again
Queens look for a dry, undisturbed place with soil that is easy to work. A sunny bank, a patch of lawn against a wall, the dry ground beneath a hedge and the soil behind a raised border all fit. If your garden in Arlesey has such a spot, it will continue to look suitable from one year to the next. The hole you saw last July has been filled in by weather, but the conditions that suited a queen are unchanged. Old burrows made by other animals can also be a draw, because they give a queen a ready-made tunnel. If something has dug into your bank or lawn edge, the hole may stay open over winter and attract attention in spring.
It also explains the odd feeling that the wasps remember. They do not. A queen simply notices the same dry, firm soil and the same shelter that her predecessor did, and judges it the same way. The old tunnel has no scent or marker that draws her back, and nothing about last year’s colony helps her.
What to do in winter about a former nest site
A winter inspection is quiet, and nothing is flying. Look at the area where the nest was and see what is there now.
- If there is a visible hole, fill it with soil and firm it down.
- If it is a lawn, rake and level the ground, and fill gaps in the turf.
- If it was beneath a slab or a step, check whether a gap has opened up.
- Remove piles of leaves, wood and rubble nearby, which provide shelter.
Wait until the weather has been properly cold. Filling a hole while the colony is still alive can leave you with angry wasps tunnelling out somewhere else, which is the opposite of what you want.
How to spot a new ground nest
In spring, mow and walk the garden with your eyes open. A new nest shows up as a small round hole, a bit larger than a finger, with a few fine crumbs of soil around it. Wasps fly directly into and out of the hole without hesitating. Early on there may be only a handful, but the number rises through the summer. Be careful if you strim or mow. Vibration travels through soil and can make a colony pour out, and people are usually stung because they did not realise the nest was there. If you see wasps rising from the grass as you work, walk away steadily, do not swat, and keep going until you are well clear.
What not to do
Do not pour boiling water, petrol or any other liquid into the hole, and do not cover it with a bucket or stone. These tricks are dangerous, they do not work reliably, and they can leave you with a furious colony. Do not stand at the entrance to watch. A short, calm look from a few metres is quite enough. Mark the hole with a cane placed well away from it, and tell everyone in the household. Keep children and pets out of that part of the garden, and leave any fallen fruit or food scraps cleared so nothing draws more wasps.
If you are unsure whether a hole is wasps or something else, such as ants or a burrowing bee, do not investigate. Watch from a distance for a few minutes and note the insects’ size, colour and flight. Bumblebees and honeybees are not treated, and for those you should contact a local beekeeper or the relevant bee organisation.
Getting a ground nest treated
Because the nest is underground, you cannot see how big it is, but the price does not depend on size. Treatment is a fixed £70 per nest, with £30 for an additional nest on the same property, and there is no call-out charge. The price is confirmed on the phone before the technician visits, and it might be more where special access equipment is needed. Nothing is done unless you agree first. Technicians are fully insured and qualified, and the service runs seven days a week, with same-day appointments and evening and weekend slots. The number to ring is 07852 111 437, and the online form and contact page work too. Say where the hole is, and if anyone in the household is allergic to stings, tell the team when you book so that it can be prioritised.
Because wasps use the same hole, you may see activity continue around it for a short time after treatment as returning workers arrive. Keep clear until the technician says it is fine, and ask what to do about filling the hole once it is quiet.
