Wasp Nest in a Hedge or Bush – What Elsenham Garden Owners Should Know

The thin strip between a hedge and the fence behind it is dry, dark and almost never visited, and it makes an ideal hiding place for a nest.

A space nobody sees

Where a hedge has been planted close to a fence, a gap often opens up between the two. It might be only a hand’s width wide, filled with old leaves and cobwebs, but to a wasp colony it is a ready-made sheltered corridor. It is out of the wind, out of the rain and almost never disturbed.

Because the gap is behind the hedge, you may not see the entrance from your side. The signs of wasps appear elsewhere: a flow of insects that seems to come from nowhere, or a hum from the hedge that has no obvious source.

Over time, a gap like this fills with leaf litter, old twigs and the debris of years. That litter provides insulation and a surface for wasps to work on. Combine it with the warmth of a south-facing fence, and the corridor is a comfortable home.

The same effect occurs where a hedge meets a garage wall, an outbuilding or a brick pier. Wherever two surfaces form a narrow vertical slot, wasps may take advantage of it. It is worth looking at every such junction in your garden.

How to spot a nest in a hidden gap

Stand back and look at the hedge and the fence together. Pay attention to:

• Wasps crawling or flying along the top of the fence panel.
• Insects entering a crack or knot hole in the fence timber.
• Traffic that seems to come and go from the end of the hedge, where it meets the fence post.
• A hum from the fence, especially in the afternoon when the wood is warm.
• Wasps emerging from the base of the fence where it meets the soil.

If you share the fence with a neighbour, ask them to look from their side as well.

If the fence is made of timber, the lower rails are worth checking. Weathered wood gives wasps material for nest paper, and a rotten post or a split rail offers a way in. Look for pale scrape marks on the surface, which show where wasps have been collecting fibre.

Why you should not look behind the hedge

It is tempting to push your hand or a stick between the hedge and the fence to see what is there, or to pull back a section of the hedge. That is exactly what you do not want to do. The gap may well be the nest itself, and a disturbance will bring the whole colony out.

The same applies to leaning on the fence, fixing a loose panel or hammering a nail. Fences transmit vibration very well, and a nest in or behind the fence will feel it at once.

If the fence needs urgent repair, tell us when you book and wait for the visit before touching it.

A torch pointed into the gap is a poor idea too, as the light and your proximity both draw the wasps.

If you must tackle the fence soon, perhaps because a panel is loose and could fall, tell us at booking. We can take that into account, and the technician will advise on the safest order of work.

Do not be tempted to cover the gap with a board or fill it with foam. Anything that closes the gap can trap the wasps and push them to a different exit.

Working with a neighbour

A fence is often shared, and so is a hedge beside it. The nest may be on your side, theirs, or in the middle, in which case both gardens are affected. A friendly word is the best start. Explain what you have seen and ask whether they have noticed anything.

Agree how to share access. The technician may need to reach both sides of the fence, and it helps if both households know when they will be coming. Any question about who pays, or whose fence it is, is for you to settle between you and cannot be advised on by us.

Keep children and pets away from the boundary in both gardens until the nest has been treated.

If you are not on good terms with the neighbour, or you cannot reach them, say so when you book. The technician may be able to treat from your side, depending on the position of the nest. Do not enter the neighbour’s garden without their permission.

If someone is stung

Move away from the fence, wash the area, remove the sting if you can see it and apply a cold pack. Watch for any change over the next while.

Call 999 straight away if there is a widespread rash, dizziness, swelling of the face, lips or throat or wheezing or difficulty breathing. People with a known allergy should speak to their GP, and tell us when booking.

Leave tools and ladders where they are until the wasps have settled.

If a panel is blown down or a post gives way while wasps are about, resist the urge to prop it up quickly. Stay away and tell us. It is better for a fence to lean a little than for someone to be stung while holding it up.
