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

By autumn people relax about wasps, but a late-season nest can be at its busiest and the hedge is often the next job on the list.

Autumn is not the end of the risk

Many people assume that wasps disappear when the school holidays finish. In truth, the colony peaks in August and can remain very active into the autumn. The weather decides when numbers fall, and a mild spell can keep a nest busy for weeks.

At the same time, this is when many gardeners reach for the trimmer. The summer growth is untidy, the days are cooler and it feels like a safe moment to cut. It is not, if a nest is still in use.

Late-season nests can seem more aggressive because food is scarcer. Foragers range more widely and are more insistent around sweet and savoury smells, so they turn up at picnic tables, bin lids and open cans. Anyone eating outdoors in September has probably noticed.

Late-season behaviour to watch for

Wasps are often more irritable in autumn. They are hungrier, more drawn to sweet things, and quicker to sting. Look out for:

• More wasps around bins, drinks and fruit than in midsummer.
• A steady line still entering the hedge on mild afternoons.
• Wasps that are slow and clumsy but still defensive near the entrance.
• A noticeable hum from the foliage, even on a cooler day.

Cooler weather can make people think it is safe to go near. Do not rely on the temperature.

Another autumn clue is the state of the hedge itself. Late summer growth often hides the lower stems, and the cover is at its thickest. A nest that has been growing since spring may be tucked deep in leaves that are only now starting to thin. As the leaves fall, a previously hidden nest can suddenly appear, and people are alarmed by its size.

The autumn cut

The tidy-up before winter is a regular task, but if wasps are visible in or around the hedge, delay it. The same hazards apply as in summer: vibration, the risk of cutting into the nest, and a swarm that is hard to escape.

If the hedge has to be cut by a certain date, for example because it overhangs a pavement, arrange the nest treatment first. A treatment takes one visit, and the cutting can follow soon after.

If you find a nest that appears abandoned, with no wasps coming or going, take a good look from a distance for several days before touching anything. A nest can look empty and still have a few occupants.

The same goes for the compost heap and any stacked logs near the hedge. In autumn people turn the heap or collect firewood, and both can disturb wasps. Check these places from a distance first, and leave them until you are sure they are quiet.

Do not wait for the frost

Some people decide to leave a nest alone and wait for the cold to deal with it. That can work in the long run, but it may be weeks away, and in the meantime you have to avoid the hedge, the path and the area around it. If you need to use the garden, a treatment now is far more comfortable.

If a sting occurs, wash the area, remove the sting if you can see it and apply a cold pack. Ring 999 without delay for wheezing or difficulty breathing, a widespread rash, swelling of the face, lips or throat or dizziness. Those with known allergies should speak to their GP.

It is also worth knowing that an empty nest will not be reused, so there is no need to worry that a nest left in place will attract a new colony.

Think about the cuttings, too. A pile of hedge trimmings left on the ground can hide wasps as well as a damp, warm spot that attracts them. Bag cuttings promptly after treatment, and do not leave piles by the hedge.

When the nest is empty

Once the colony has died back, whether naturally or after treatment, you may be left with a grey paper nest in the hedge. If you want it removed, ask the technician at booking whether that is possible, since it depends on where it sits and how easily it can be reached.

If you choose to leave it alone, it will break down over time. It will not harm the hedge, though you may want to check it is truly empty before you cut around it.

Whatever you decide, look at the hedge again in spring, because a new colony begins from late April and can choose a spot not far from the old one.

Photographing the nest before and after treatment can be helpful if you want to compare notes with the technician, or if a neighbour wants to see what was done. Take the pictures from a safe distance, not from close up.

Booking

Phone 01245 327274 or use the form on the contact page. Mention if anyone at home is allergic so the booking can be prioritised.

Late bookings are no problem. We take bookings through the autumn, and the fixed price does not change with the season. If you are unsure whether a nest is still active, describe what you have seen and the technician will advise.

Next spring, set a reminder for late April to look at the hedge. Colonies begin building then, and a quick glance on a warm day will show whether anything has started. Acting while a nest is small keeps the problem simple.
