Found a Wasp Nest in Your Loft in Bentley? Here's What to Do
The loft hatch is the one door between you and a colony, so the safest response is to treat it as a barrier, keep it shut and let a trained technician do the going up.
Treat the hatch as the boundary
If you have confirmed or strongly suspect a wasp nest above your head, the hatch becomes the most important object in the house. On one side is your landing, and on the other is a space that may contain thousands of insects that react badly to disturbance. Almost every bad outcome with loft nests starts with somebody opening that hatch to take a look.
It is worth being blunt about this. A loft is dark, enclosed and often warm, and a nest in it can sit within an arm’s length of the opening without being visible from the ladder. By the time you see it, you are close enough to be a threat from the colony’s point of view. Wasps defend a nest by swarming and stinging, and several can sting at once.
So the first rule is simple: close the hatch, leave it closed and tell the rest of the household not to go up, including for the Christmas boxes or the suitcases you were planning to fetch.
What the insulation can hide
Insulation is the reason loft nests are so often found late. Wasps will build in the quiet space between joists, behind a layer of fibreglass or tucked against a timber at the edge of the roof. From the hatch you may see nothing but a grey blanket while a nest the size of a football sits just out of view.
It also means you should not lift, move or compress the insulation to search for a nest. Doing that shakes the structure, and a wasp that finds its home being pulled apart will come out in force. A torch pointed from the hatch is not a safe halfway option either, because the light and the sound of a person moving about are enough to unsettle the colony.
Instead, use what you can observe from outside the loft. Watch the eaves and the roofline on a dry afternoon from a safe distance on the ground, and look for wasps flying steadily in and out of one spot. That is the entrance, and it tells the technician where to begin.
Things to avoid while you wait
There is no shortage of well-meant advice online, and some of it does real harm. These are the things to steer clear of:
- Spraying anything through the hatch gap. It will not reach the nest, and it will make the wasps that are near it far more aggressive.
- Using smoke, burning paper or a fogger of any kind in the roof space. That is a fire risk as well as a stinging risk.
- Blocking the outside hole. The colony will find another way, and that may lead into a bedroom or the kitchen.
- Going up the ladder to see how big it is. The size does not change the price, and you gain nothing from knowing.
- Leaving the hatch propped open to let wasps escape. They will simply spread through the house.
None of these is clever or quick. All of them make the job harder for whoever has to deal with the nest later.
If you have already tried one of them, do not worry. Just tell the technician what you did when you book, so they know what to expect when they arrive.
How the booking and the visit work
Treatment of a wasp nest is a fixed £70 per nest, with any further nest on the same property costing £25 more. There is no call-out charge, and the technician is fully insured and qualified. The price is confirmed with you over the phone first, so there are no surprises when someone arrives. The only thing that can push it up is difficult access where special equipment has to be used to reach the nest, and you will be told about that before agreeing to anything.
The easiest route is the online booking form, or the contact page if you prefer to write a few lines. When a form is submitted, the technician for your area is alerted by SMS and email, seven days a week, so a weekend discovery is not left sitting in an inbox. Same-day service is offered, and weekends are covered.
When the technician turns up, show them where you have seen wasps and where they are flying in from outside. After that you can usually leave them to it. The treatment of the nest is their job, and you have no need to be in the loft or under it.
After the nest is dealt with
Expect a few dead wasps near the hatch and in the rooms below over the next day or so, and a few late arrivals that return to the old entrance. This is normal. Brush the dead ones up with gloves on rather than bare hands.
Leave the hatch closed for a day or two. Once things have settled, it is reasonable to check the loft, ideally with someone else holding the ladder, and see whether the empty nest has been left in place. If you want it taken down, you can ask the technician at booking whether that is possible, rather than hoping.
Finally, use the quiet months to look for the way in. A small gap at the eaves, a cracked vent cover or a hole where a pipe passes through the wall is all a queen needs in April. Closing it once the nest is gone is the best protection for next year, and it is a good moment to mention it to a roofer if the gap is up high. Homes in Bentley are no different to anywhere else on this point, since the cause is always a gap and a warm, dry space.
