Wasp Nest Treatment in Coombe – Why Early Action Matters
Decking, pergolas and raised beds have hollows underneath and inside, and a nest there sits right beside the places you eat and relax.
The space under your feet
A timber deck is a platform on joists, with a gap beneath it that is dry, shaded and rarely disturbed. A pergola has posts, beams and joints. A raised bed has a cavity behind the sleepers. All of these are suitable places for a wasp to start a nest, and all are in the part of the garden where people spend their time.
Late April is when wasps begin building, depending on the weather. In Coombe, as in any garden with outdoor structures, the first sign may be a wasp disappearing between two boards or flying low towards the base of a post.
Raised beds made of sleepers are worth special mention. The sleepers are heavy and have natural cracks, and a bed sited against a fence has a dry void behind. Gardeners lift planks and move soil, which disturbs whatever is behind them. Check before you start digging.
Signs under and around timber
Look at the garden as the wasps do.
- Wasps entering a gap between deck boards or at the edge of the deck.
- Traffic at the base of a post, where it meets the ground.
- A hum beneath your feet when you walk across the deck.
- A hole beside the deck frame, at the lawn edge.
- Wasps around the underside of a pergola beam or the back of a bench.
If you notice a hum underfoot, step off the deck slowly and quietly. Do not stamp or jump.
Pergolas covered in climbers hide the framework. A nest may be tucked into a joint under the foliage, and the first you know is a wasp flying out of the leaves. Watch the planted areas as you would a hedge.
Why placement raises the stakes
A nest under a deck is a few centimetres from the people above. A footfall, a dragged chair or a barbecue being moved can disturb it. Children, running over the boards, are especially likely to trigger a response.
The colony grows through the summer and peaks in August with anywhere from 2,000 to 10,000 or more wasps. Early treatment means a calmer visit, and the deck is back in use sooner. The fee is £120 per nest, fixed, with one visit guaranteed.
Another point is that the sun warms a deck and wasps are active in warm weather. Mid-afternoon, with the boards warm, is when you are most likely to see them. If you see traffic at that time, note it.
Keep an eye on barbecue and fire pit areas too. Wasps are drawn to the smell of cooking, and a nest nearby makes every meal outdoors more of a risk. Postpone the barbecue until the nest has been treated, or move it to the far side of the garden.
If you have outdoor lighting under the pergola, switch it off at dusk while the nest is in place.
Keeping safe until the visit
For the time being, treat the structure as out of bounds.
- Keep everyone off the deck or away from the pergola.
- Move chairs, tables and barbecues away from the area.
- Cover food and drink, and clear bins nearby.
- Do not lift boards or poke beneath them.
- Watch for wasps entering the house if the deck adjoins a door, and keep the door shut.
If you are stung, wash the area with soap and water, remove the sting and apply a cold pack. Call 999 for signs of a serious reaction.
Children's play equipment on or beside a deck, such as a sandpit or playhouse, can be the first thing disturbed. Move it only if you can do so without going near the nest.
Also think about the furniture and the barbecue. A heavy table dragged across boards makes vibrations that carry through the structure to a nest below. Lift, do not drag.
Plan the visit with the technician in mind. A deck with a gap of a few centimetres beneath it needs a different approach from one that is raised higher, and the technician may need to reach the nest from the side. Tell us how high the deck is, what it is made of and whether there is a gate or side access.
Do not be tempted to pour anything beneath the boards, however tempting it seems. Water, cleaning products or other liquids will not help and may anger the wasps. It is also best not to put plastic sheeting over the area, since wasps will look for another exit.
Finally, if your deck or pergola is a rental feature, such as part of a holiday let or a cafe terrace, let the people who use it know that it is out of bounds until it has been treated.
Access for the technician
A deck may need to be accessible from the side or the end. If you have stored items beneath it, tell us. We will talk through access when you ring.
If your deck is attached to the house, check the join between the deck and the wall. Gaps there can lead into the cavity.
Booking
To book, call 01622 410 019 or send an enquiry through the online form on the contact page. We are open every day of the week and can often offer same-day service, plus evening and weekend slots. Any further nest on the property comes to £60 extra. Whoever attends is fully insured and fully qualified. Tell us if anyone is allergic to wasp stings so that your booking can be prioritised.
After treatment, ask the technician whether the empty nest can be taken down, and whether anything needs doing to the deck. Do not take up boards until you have been told it is safe.
