Wasp Nest in a Cavity Wall – How Professionals Treat Hidden Nests in Ash
A number of well-meant beliefs about wall nests lead people to take risks or wait too long, so here are the most common, one by one.
Why myths spread
Wasp nests are a seasonal problem that most people deal with once every few years. In between, they rely on half-remembered advice, things a neighbour said or something seen online. Some of it is sound. Some is not, and a few of the common ideas lead people straight into trouble.
For householders in Ash, with a nest in the wall, it is worth checking what you have heard against what is true. None of the following needs special knowledge, only a little common sense and a willingness to stay back from the wall.
Here are the most frequent myths, with the reality behind each.
One of the reasons myths persist is that wasp problems are seasonal, so the lessons are forgotten by the next summer. Another is that the wasps themselves are alarming, and people latch onto any idea that feels like action. Taking a moment to separate fact from folklore is time well spent.
Myth: it will fall off by itself
A nest in a tree or a shed might eventually decay or drop. A nest in a cavity wall does not fall anywhere. It sits in a protected space, away from wind and rain, for as long as the colony lives. When the colony dies in autumn, the paper structure stays where it is.
Waiting for the nest to disappear is therefore a plan that works only in the sense that the wasps eventually stop. In the meantime, you live with a colony that grows through the summer.
The fact is that a nest in a wall is not going to move. If you want it dealt with, it needs treating.
Some people also suppose that old nests can be knocked down for fun or collected as a curiosity. A paper structure inside a wall is not accessible, and trying to reach it means opening the wall, which we do not advise. If you are curious, ask the technician afterwards whether it can be taken down.
Myth: you can smoke or flood them out
Some people think they can drive wasps out with smoke, water or a hose. This is both ineffective and risky. A fire near a building is dangerous. Water in a cavity wall can cause damp. And neither deals with the colony.
What they do achieve is to anger the wasps. A hose pushed at an entrance often results in a stream of defensive insects, and the person holding the hose is the nearest target.
The same goes for smoke bombs, candles and similar devices. They are not designed for walls, and they may send wasps into the house instead of out into the open.
Another idea is that strong smells such as peppermint or vinegar will drive them away. Smells may make a difference to a wasp that is wandering around your patio, but they do nothing to a colony in a cavity.
Myth: blocking the hole will starve them
This is the most common and the most damaging idea. The thought is that if the wasps cannot get out, they will die. In practice, wasps find another way. Cavities have many small gaps, and a blocked front door often means wasps in the bedroom.
It also does nothing for the colony in the meantime, which carries on inside. You end up with a nest, plus a new problem, and nothing gained.
The correct approach is to leave the entrance alone until the nest has been treated. After that, seal it properly.
There is no harm in being sceptical of advice that sounds too easy. If it promises a quick fix without a professional, ask what happens if it does not work, and who will be next to the wall when it fails.
Myth: it is too late, or too early
Some people believe that a nest can only be treated at a certain stage of the season, or that it is too early to do anything in May and too late in October. Neither is true. A nest can be treated at any point when it is active, and the price does not change with the time of year.
A second misunderstanding is that a few wasps cannot be a nest. Even a modest flow of insects at one gap can mean a growing colony.
A fixed £120 per nest is the whole fee, one visit guaranteed, with no call-out charge on top. A second nest at the same property is £60 extra.
Some believe that wasps are only dangerous if you provoke them. That is partly true, but a nest can be provoked by things you would not think of, such as vibration from a lawnmower or a ball hitting the wall.
What actually works
A professional visit, with a trained and fully insured technician treating the nest through the entry point, is what works. Your own part is to stay clear, keep children and pets away and give clear information.
Tell us at booking if anyone in the household is allergic to stings, so the booking can be prioritised. Ask whether the empty nest can be taken down. After treatment, once the wall is quiet, have the gap sealed.
The easiest ways to book are the phone, 01622 410 019, or the online form on the contact page. We work seven days a week and offer same-day service, as well as evening and weekend appointments.
If you remember one thing, make it this: leave the entrance open, stay away and call.
If you have heard another idea and are unsure about it, ask. We are happy to say whether it is sensible, and to explain why the usual advice is to leave the hole alone. A short question now costs nothing and can save a great deal of trouble.
