Wasp Nest in a Hedge or Bush – What Charlton Garden Owners Should Know
Before anyone reaches for the hedge trimmer, a few calm minutes of watching can confirm whether wasps are nesting in a shrub, and where exactly the entrance is.
One wasp is not a nest, a line of wasps is
Wasps visit hedges and bushes for several reasons. Some are scraping fibre from a woody stem to build with, some are hunting insects among the leaves, and some are simply passing through on the way to a flower or a bin. None of that means there is a nest. What does is repeated, purposeful traffic: wasps arriving at one point, vanishing into the foliage, and reappearing a short time later to fly off in the same direction. That flight path is the clearest evidence you will get. Nests in hedges are often entirely hidden by leaves, with only a small opening low down or on the shady side. You may never see the papery shell itself, so the behaviour of the insects is your main clue.
How to watch without taking a risk
Choose a warm, still, dry part of the day, when wasps are active and easiest to follow. Stand at least three or four metres away from the hedge, and keep your movements slow. Do not wave your arms, and do not stand in the line they use to enter or leave.
- Watch one section of the hedge for five to ten minutes at a time.
- Note the height of the entrance relative to the ground, and which side it faces.
- Count roughly how many wasps pass in a minute, without trying to be precise.
- Look for wasps carrying anything, such as a pale pellet, which suggests building or feeding.
Do not use binoculars as an excuse to go closer. A phone camera with zoom lets you record what you see and show it to the technician later, from a safe spot.
Marking the spot without going near it
Once you have a sense of where the entrance is, mark the area so nobody walks into it. A cane placed at a good distance and a piece of tape tied on the path side is enough. Tell everyone at home. Children are the most likely to wander into a hedge after a ball, and a visitor who does not know about the nest is at the greatest risk of a sting. Stop any work near the hedge in the meantime. That includes trimming, strimming, tying in branches and pulling weeds from the base. Even light work shakes the foliage and may cause the colony to defend itself. Charlton gardens often have mixed planting along boundaries, so it is worth walking the full length of any hedge before ruling it out.
If you rent the property or share the garden, pass the information on to whoever else uses it, including anyone who looks after the grounds. A short message with the location of the hedge and the wasps’ entrance point is better than a general warning.
What it looks like when the nest is in the foliage
A hedge nest tends to hang from the inside of the branches or sit tucked into the fork of a thick stem. In its early stages it can be as small as a golf ball, and it grows to the size of a football or more by late summer, when a colony can hold as many as 2,000 wasps. Because the foliage hides it, the first sign is often an increase in wasps around the hedge in June or July. Other clues may include a faint rasping sound in warm weather, small pieces of chewed material on the leaves below, and wasps that seem unusually bold near the hedge. If you notice a dark mark among the leaves that does not look like a normal gap, do not part the branches to look.
Timing offers a clue too. A hedge that was quiet in May and busy by July is more likely to hold a growing colony than one with the same number of wasps all season. If you only notice wasps in late summer, the nest may have been developing for months without you knowing.
Keeping the household safe in the meantime
Keep children and pets out of that part of the garden. Hang washing away from the hedge, and do not sit near it with food or sugary drinks. If you must pass close by, walk steadily rather than running, and do not swat at any wasps that fly near you. If anyone is stung, wash the area, remove the sting if you can see it and use a cold pack. If there are signs of a serious allergic reaction, such as swelling of the face, lips or throat, wheezing or difficulty breathing, dizziness or a widespread rash, call 999. A person with a known allergy should speak to their GP about their situation, and should tell the technician when you book so that the booking can be prioritised.
Keep windows and doors on that side of the house closed during the hottest part of the day if wasps are numerous, and use fly screens where you have them. Do not leave open drinks outside, since wasps seek out sugar.
Arranging treatment and what to say when you ring
The treatment price is fixed at £70 per nest, with £30 for an additional nest on the same property. There is no call-out charge, and the price is confirmed on the phone before the technician visits. If the nest is somewhere that needs special access equipment, such as high in a tall hedge, the price might be more, and you will be told before anything happens. Nothing is done without your agreement. When you ring, describe the hedge or bush, the side the wasps use, roughly how high the entrance is and how many wasps you can see. Technicians are fully insured and qualified, and the service is open seven days a week, with same-day appointments, evenings and weekends. To book, ring 07852 111 437, or send the online booking form or the contact page message.
