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

The easiest, calmest time to deal with a nest is when it is the size of a golf ball, and the signs to look for in spring are quite different from those in August.

The queen’s spring search

Every wasp colony starts with a single queen. After winter she emerges, usually from late April depending on the weather, and spends days looking for a suitable site. She will inspect cavities, loft corners, shed roofs and holes in the ground, crawling slowly in and out. This is a very different picture from the summer swarms most people associate with wasps.

A single large wasp investigating a gap in your property in spring is worth noting. If she settles, she will start to build a small nest on her own, laying eggs in tiny paper cells, and feeding the first grubs herself.

What the early signs look like

In the early weeks there are very few wasps, so the signs are subtle. You might see one wasp going in and out of the same gap a few times a day, a small amount of fresh scrape marks on fence rails and a faint paper smell. Because there is no crowd, it is easy to dismiss.

• One large wasp repeatedly visiting the same spot.
• A single wasp carrying pellets of fibre.
• Pale scraping marks on timber in warm weather.
• Small dark droppings under a gap that were not there before.

These signs matter because they pinpoint the site before the colony has grown. Once the first workers emerge, usually in early summer, numbers start to climb.

Check a few likely spots at the same time each week. Spring is a good time because the weather is mild and the wasps are few, so you can look without much risk. The roof edge, the shed, the garage, the compost area and the bases of hedges are all good places to start. Keep to a distance of a few metres, and move on if you see a wasp acting as though it owns a gap.

Bear in mind that a spring queen is often a little dull and sluggish on cool mornings, and then very active in the warm part of the day. If you see her in the afternoon, you are more likely to notice her pattern.

How fast things change

The nest grows slowly at first and then quickly. After the first workers hatch, the queen stays inside and the workers take over building and feeding. Each new batch of workers is larger than the last, and by midsummer a nest that began as a handful of cells can have hundreds of wasps. By August it can hold thousands, and a large colony may contain 10,000 or more.

This growth is why a small nest in May is not something to put off. It will not go away on its own, and the longer it is left, the more wasps there are and the more difficult it is to manage safely.

Unlike the later workers, a queen is relatively large, with a bulkier body and a deep, slow buzz. She can sting, and though she is usually not aggressive when alone, she should still be left alone. The sight of a lone queen exploring is not a signal to do anything dramatic. It is simply a prompt to watch.

If you see a wasp, do not assume that she is the only one who could found a nest on your property. Several queens may look at the same site, and only one may settle, but occasionally two nests will start in neighbouring spots.

What to do in spring

If you spot early signs, keep an eye on the gap from a distance. Do not block it, spray it or poke it. A queen disturbed at this stage may move, but she may also start again nearby, or defend the site fiercely. Note where the gap is and what is around it.

It is also a good time to check likely places around the property, such as the loft hatch, the shed roof, airbricks, the eaves and the bases of hedges. A short look each week gives you the best chance of catching a problem early. If you can, tidy up the places where wasps might hide, such as piles of timber or old sacks, but only if you can do so without disturbing a nest.

Why early treatment makes sense

Because the price is fixed at £90 for a nest, there is no cost advantage in waiting, and there are several reasons to act sooner: fewer wasps, less risk of stings, less disruption to your household and a smaller chance of the nest spreading through a cavity. A small nest is also less likely to cause staining or damage to a ceiling or wall.

Early treatment suits people who are anxious about stings, those with allergic family members and anyone with a business to run. The aim is to deal with the problem before summer arrives.

Some people ask whether it is better to wait for a nest to grow before arranging a visit. In practice there is little benefit in waiting. The technician will treat the nest at the same fixed price however large it is, and a small nest is easier to locate and less likely to be hidden in a difficult place. If you can see a clear sign in spring, you can book then.

If you have had a nest in previous years, check the same area and the surrounding spaces in late April. Wasps do not reuse an old nest, but a site that suited one queen might attract another, and the early signs can then be caught at once.
