Can You Remove a Wasp Nest Yourself? Advice for Lavendon Homeowners
A grey, papery nest in autumn can look abandoned, but that is not always the case. Here is how to judge whether it is still active and what to do about it.
The nest that looks finished
As summer turns to autumn, many householders notice a grey, papery ball under the eaves or in a hedge and wonder whether it is a leftover from the season. The idea that a late-year nest must be dead, and can simply be knocked down, is widespread. It is sometimes true, but it is a poor thing to assume.
The colony follows a yearly cycle. A queen starts it in early spring, workers expand it through the summer, and in late summer it reaches its peak, when a nest can hold as many as 2,000 wasps. Only after that does it decline, and the timing varies with the weather. A mild autumn can keep a nest busy for longer than you might expect.
For anyone in Lavendon who has found a nest and is wondering whether it is safe to remove, the first job is to find out whether it is still in use.
Another thing to bear in mind is that wasps do not carry on using a nest through winter. The workers die off, and the new queens go elsewhere to hibernate. So a quiet nest in November is usually finished, but a quiet nest in September on a cold morning is not necessarily so.
Signs that it is still active
The answer is nearly always found by watching, not touching. Observe from a distance on a mild, dry day, in the middle of the day.
- Traffic. Wasps going in and out of the entrance, even a few at a time, mean it is in use.
- Sound. A low hum or rustle, if you are able to hear it from a safe spot, points to activity.
- Fresh material. A pale, new-looking edge or a still-growing nest suggests recent building.
- Defensive behaviour. Wasps that fly towards you as you approach are protecting something.
If you see none of these over several days, including warm ones, the nest may be finished. But the absence of wasps at one moment does not prove the nest is empty, since cold or wet weather can suppress activity.
Take your observations at the same time on several days, as wasp activity follows the temperature. A cold, damp morning can make a busy nest look deserted, and the same nest at noon on a mild afternoon may be busy.
Why knocking it down is still a gamble
If a nest looks quiet, the temptation is to get it down before it becomes an eyesore. The risk is that a nest which looks empty may still contain wasps, especially on a cool morning when they are less active. Knocking it, poking it or pulling it away will bring them out immediately.
Late-season wasps can also be more irritable than in early summer. The colony is starting to fall apart, workers have fewer tasks, and they are hungry and easily upset. The insects around a failing nest are not harmless just because the season is ending.
Even a dead nest can be awkward. It may be fixed to a roof timber, a soffit or a branch, and removing it can involve a ladder and a reach. An empty nest can be taken down safely, but ask a technician whether that is possible, rather than guess.
There is also the question of what is nearby. A nest hanging in a hedge is in the way of anyone trimming it, and a nest in a loft or shed might be disturbed when you next open the space. Planning the removal for a time that suits you, with the right help, is far better than coming across it by accident.
What to do in the meantime
Leave the nest in place for now. Keep clear of it, and warn anyone who might brush against it, particularly if it is in a hedge, under a gutter or over a path. Keep children and pets away, and avoid cutting, trimming or hosing near it.
If you think it is inactive, watch for a few days and write down what you see. If wasps are using it, treat it as live. If you are not sure, treat it as live.
Do not block the entrance, spray it or try to burn it. If anyone is stung, wash the area, remove the sting if you can see it and use a cold pack. Dial 999 if you notice swelling of the face, lips or throat, breathing difficulty, dizziness or a widespread rash. A known allergy is something to discuss with your GP.
If you must walk past the nest, such as on the way to a gate, take a different route if there is one, or wait until you are certain it is calm. Move slowly and do not stop to look.
Getting an opinion and a treatment
Wasp Exterminator Hertfordshire charges £70 per nest, plus £30 for each additional nest on the same property, with no call-out charge. The price is confirmed on the phone before the technician visits, and you decide whether to go ahead. If special equipment is needed to reach the nest, the price might be more, and that is explained first.
A call to 07852 111 437 is the quickest way to book, and the online form and contact page also work. The technician for your area is alerted by SMS and email, seven days a week, with same-day, evening and weekend visits offered for homes and businesses. Describe what you have seen and when, including how recently you saw any wasps at the nest.
If anyone at the property is allergic to wasp stings, say so to prioritise the booking. Ask whether the empty nest can be taken down once it has been dealt with. If it is in a hedge or tree, mention that too.
If you are not sure whether the nest is active, say that when you book. The technician can advise on what to do, and it costs nothing to ask for guidance before you decide how to proceed.
