How to Tell If You Have an Active Wasp Nest on Your Ranskill Property

Hedges, mature trees and dense shrubs make excellent hiding places. This guide shows what to look for in the greenery without getting close enough to be stung.

Nests among the leaves

Not all nests are built into brickwork. Wasps readily hang a nest from a branch, tuck it into the heart of a thick hedge or build it in a hollow tree. In a leafy garden it can be quite hard to spot until the colony is well established.

Gardens in and around Ranskill, with their mix of mature hedges, fruit trees and boundary planting, offer many such places. The checks below work for any garden with a lot of greenery.

A nest in foliage is usually found by its traffic rather than by sight, so patience matters more than sharp eyes. Pick a warm hour, stand where you can see a wide stretch of hedge or branches at once, and let your eyes settle on any point where insects seem to flicker in and out of the leaves.

Spotting traffic in the foliage

In a hedge or bush the signs are still about movement. Look for a gap in the leaves where wasps keep flying in and out, usually low or at the middle of the hedge. Watch the spot from several metres away, and look for a pattern repeating over a few minutes.

Nests in trees are often attached under a branch or in a fork, where the structure is protected from rain. In a hollow trunk or a crevice, the only clue may be the traffic through a knot hole.

• Wasps flying straight in and out of a single gap in a hedge.
• Grey, rounded structure visible between branches in winter or when leaves are thin.
• Wasps repeatedly landing on bark and flying off with a small piece of wood.
• A faint hum from a hollow trunk on a warm day.

In winter, when the leaves have dropped and the colony has gone, an old nest can sometimes be seen in a bare hedge or tree. That is a handy way to learn where wasps like to build, but it does not make it safe to touch while the weather is still warm.

Late in the day, when the sun is lower, the flight line often shows up better against a dark background, so a second look in the evening can be worth the effort. Stay indoors or well back, and let the insects come to you only on their own flight path.

Why hedge cutting is the risky moment

The commonest way people get into trouble with a nest in greenery is by cutting into it. Hedge trimmers, strimmers and pruning shears make vibration and noise, and a wasp nest hidden inside a hedge can be hit before anyone has seen it.

If you notice wasps in a hedge before you begin, stop work. Put the trimmer down gently, walk away and tell others to keep out. Do not carry on with the rest of the hedge as though nothing has happened.

When trimming begins in spring, check the hedge from a distance first, and watch for traffic before you start. Delay the job if you see wasps in the foliage.

Fruit trees need a mention. In late summer, fallen apples and plums attract wasps, and it can be difficult to tell feeding wasps from nest traffic. If wasps are all over the fruit but are not flying in a line to a single spot, they are most likely foraging. Pick up windfalls regularly and keep the area underneath clear.

Shrubs, compost heaps and low cover

Low planting also hides nests. Dense shrubs near the house, piles of branches, compost heaps, log stores and overgrown corners all offer shelter. A nest in a log pile or a thick bush near the back door may be only a few steps from where children play.

Keep an eye on spots you do not use often. A quiet corner of the garden, an overgrown bank or a bramble patch can host a colony without anyone realising for weeks.

Garden waste deserves a thought as well. Bags of clippings, stacks of pallets and upturned flowerpots all create small hollows. Move them carefully, or better still, look first from a distance and see whether any wasps fly out when the sun is on them.

What to do if you suspect a nest in the greenery

Keep everyone away, including pets, and avoid mowing, trimming or watering close to the area. Do not spray it with a hose, shake the branches or prod the foliage. Note where it is, using landmarks such as a gate post or a bench.

If the nest is high in a tree, tell the technician how high and whether there is open ground below. The price might be higher where special access equipment is needed, and you will hear this before anything is done.

Take a photo from a safe distance if you can, and describe the position as precisely as possible.

If the nest is on a boundary, it may be hard to say whose side it is on. A quick word with the neighbour is sensible, since they may not know it is there, and the technician can advise on what is practical when they attend.

Wasps do not choose a spot to annoy anyone. They simply need shelter, and a thick hedge provides it. A treated nest is the end of the problem for that season, and the hedge can be trimmed afterwards.

Booking

The Wasp Exterminator treats nests for a fixed £70 per nest, with an additional nest on the same property at £25 extra. There is no call-out charge, and domestic and commercial sites are covered seven days a week, with same-day service offered. Ring 07798 792 774 or use the online booking form.

The price is confirmed before the technician visits, and no work is done unless you agree. A colony peaks in August and can hold as many as 2,000 wasps, so earlier is better.

Commercial grounds, such as pub gardens, campsites and nurseries, are covered in the same way as homes.
