Wasp Nest in a Cavity Wall – How Professionals Treat Hidden Nests in Babbinswood
Garage, extension and outbuilding walls give wasps quiet cavities, and one property can sometimes end up with more than one nest.
Overlooked walls
Householders watch the main walls of the house and ignore the others. Yet garage walls, extensions, conservatory bases and garden outbuildings often have cavities, gaps and unused spaces that are rarely disturbed. Wasps like exactly that: a dry, quiet, sheltered corner with a small opening.
The result is that a nest can grow for weeks before anyone notices, particularly in a garage that is used only now and then. By August the colony may hold as many as 2,000 wasps.
Extensions in particular can create hidden voids where new walls meet old ones. A thin gap at the junction, or a space behind cladding or at the eaves, may be easy to enter and impossible to see into. Wasps find those spaces readily, and a householder rarely thinks to look.
Signs to look for
Spend a few minutes at the start of the summer walking round the outside of each building.
- wasps going in and out at a gap near the garage door frame or under the roof edge
- a hum when you stand in the garage with the door closed
- wasps on the inside of garage windows, trying to get out
- gaps where an extension joins the original house
If you spot activity, look from a distance and do not stand in the flight path. Avoid going into the garage or outbuilding if wasps are coming in, and keep the door closed.
A quick tip is to look at the garage in the evening, with the door closed and a light on inside. Wasps that are inside and trying to leave will gather at the window, and any glimmer of daylight at a gap in the wall may show where they are coming in. It is a safe way to find an entrance from a distance, so long as you do not open the door and walk into the flight path. Take care never to stand directly in front of an entrance, and never reach into a gap to feel for a nest.
More than one nest on a property
It is not unusual for two nests to be found on the same property, for instance one in the house wall and one in a shed or garage. They may belong to separate colonies. If you have seen traffic in two different places, tell us when you book.
Wasp Exterminator Shropshire treats nests at a fixed £80 per nest, with one visit guaranteed. An additional nest on the same property is £40 each, so reporting both at the start allows them to be dealt with in a single visit. There is no call-out charge, and nothing extra for location or time of day.
When you book, describe each location separately. Say which is the house, which the garage or shed, and where you saw the wasps at each. The technician can then plan the visit and bring what is needed for both.
Why not do it yourself
A garage or outbuilding feels like a safe place to experiment. It is not. A colony in a wall can respond fiercely to disturbance, and the confined space means you may have little room to retreat. Blocking the opening, spraying or opening the wall can send wasps into the garage or house.
Leave the space alone, keep the door closed and keep children and pets out. Move anything you need from the garage only if it can be done without disturbing the wasps. If someone is stung, wash the sting, remove it if visible and apply a cold pack, and call 999 for swelling of the face, lips or throat, wheeze, dizziness or a widespread rash.
A second thing to remember is that wasps from one colony can wander widely, so a nest in the garage does not rule out another in the house. Treat each sighting on its own merits and record where you see traffic, rather than assuming they all come from one place.
If you are unsure whether you have one nest or two, say so. The technician will ask a few questions and may be able to tell from your description before they arrive.
What the technician needs
Make sure the technician can reach each wall involved, including any locked garage or side gate. Say which wall is which and how you know. Expect a qualified, fully insured technician and a safe, effective treatment.
Open seven days a week, the business offers same-day service, with evening and weekend appointments. Domestic and commercial customers are served alike. You can ask whether empty nests can be taken down, although with cavity nests this depends on what is found.
If the outbuilding belongs to a neighbour, or you share an access path, speak to them in good time. Treatment needs the agreement of whoever owns or controls the building.
Booking and sealing afterwards
Get in touch on 07916 322 280, or by the online form on the contact page. If it is urgent and outside office hours, send the form and ask for emergency service. Babbinswood and nearby villages are covered. If anyone is allergic to stings, say so at the start.
Once the technician confirms the nests are inactive, close the gaps in the garage and extension walls with the help of a competent tradesperson. Check outbuildings in early April each year to catch the next queen before a nest begins.
Finally, keep stored items in the garage tidy and away from the wall for the rest of the season, so the technician can reach it and nobody has to move boxes in the middle of a flight path.
