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

A nest in a hedge is not a single event but a season, and knowing the calendar tells you when to look and how quickly to act.

Late April and May: the start

Wasps start building nests from late April, depending on the weather. At this stage the nest is small, perhaps no bigger than a golf ball, and only a few wasps are involved. In a hedge, that can be a gap at the base, a hollow among the stems or a hole in the soil.

This is the easiest time to deal with a nest, because the colony is small and the entrance is simple to identify. It is also the time when very few people notice anything, because there are only a handful of wasps and they are quiet.

A short walk along the hedge on a warm day in May is worth the time.

Warm springs bring the start of the season forward, and cold spells can delay it. Do not rely on the calendar alone; look at the hedge itself. If it is warm and dry and you see a wasp investigating the same spot repeatedly, that is a sign.

June and July: growth

Through early summer the colony grows steadily. The nest gets larger, new wasps emerge and the traffic at the entrance increases. A hedge that seemed quiet in May may now have a clear line of wasps in and out.

This is the time when many people first notice a problem. You may spot wasps when you cut the hedge, or find one in the kitchen. Take the signs seriously:

• A regular flight line to one point.
• A hum from the foliage on a warm afternoon.
• Wasps at ground level around a hole.

Acting now is still much easier than waiting.

Keep a record. A note of when you first saw wasps in a particular hedge will help the technician to judge how established the nest might be. It also helps you to see a pattern from year to year, if the hedge is a regular favourite.

August: the peak

The colony peaks in August, and a nest can hold anywhere from 2,000 to 10,000 or more wasps. The entrance is busy all day, and the wasps are often more defensive. Any vibration or disturbance near the hedge can trigger a large response.

This is also the season of picnics, barbecues and school holidays, which puts more people in the garden at the very moment the nest is at its largest. Children playing near a hedge, dogs sniffing around and adults trimming are all at risk.

Do not go near the hedge. Keep everyone back, and arrange a treatment as soon as you can. The fixed price is the same whether the nest is small or large.

There is one more point to make about August. Because the colony is at its largest, a single disturbance can send out a very large number of wasps at once. That is why even people who have lived alongside a nest all summer may be caught out by a single trimming session.

September and October: the decline

As the weather cools, the colony slows. The number of wasps entering and leaving falls, though they can stay irritable and interested in sweet things. A nest can still defend itself in autumn, so keep away until you are sure it is inactive.

Late in the season, people often notice a large grey nest in the hedge after leaves fall. If you see one with no wasps, it is probably empty, but check from a distance for a few days before touching it. The technician can advise on removal.

Autumn is also when the hedge gets its main trim. Check carefully before you start, since a late nest may still be active.

Do not assume that a nest is dead because the weather has turned cold. A few warm days can bring the activity back. Wait for the technician’s view before you touch it.

What to do at each stage

A simple calendar helps:

• Late April to May: walk the hedge on a warm day and watch for first signs.
• June to July: check weekly, and before any cutting.
• August: keep well away from any active hedge, and book promptly.
• September to October: check before the autumn trim.

Away from the hedge, take the sting out if you can see it, wash the sting with water and hold a cold pack against the skin. Call 999 immediately if you notice dizziness, wheezing or difficulty breathing, a widespread rash or swelling of the face, lips or throat.

Share the calendar with others who help in the garden. A gardener who visits monthly may arrive in the middle of August without any idea of what has happened since their last visit. A quick message avoids trouble.

Remember that the numbers are a guide, not a promise. Weather, food supply and position all affect how fast a colony grows, so some nests peak early and some late.
