The Wonderful Wasp

The Wonderful Wasp

It’s that time of year again. No matter whether you’re in the garden having a family BBQ, or sat in the pub garden enjoying a cold pint, it’s often accompanied by flappy hands and silly dances trying the scare away the wasps.

Yet in fact wasps don’t cause too much of an issue – until you’re unlucky enough to be sharing your home with a wasp’s nest! So yes – wasps are a nuisance when you’re eating al fresco and an absolute nightmare if they nest in your home – and we’ll come to that. But we should remember that the wonderful wasp has, like every creature, a role to play in nature. So if you’ve ever wondered what the point of wasps is do check out this website Are Wasps Beneficial to learn about their valuable role in the environment. For starters, wasps are  pollinators in the same way as bees!

British wasp species

There are two main species of wasps in the UK. They are:
  1. The Common Wasp, Vespula Vulgaris  and …
  2. The German/European Wasp, Vespula Germanica
This isn’t including other solitary wasps such as parasitic wasps. 

Both of these species can build nests in trees, walls, buildings, roofs and underground. Indeed, pretty much anywhere. The difference between these two species of wasp is, in the main, size. They’re both yellow and black and they both sting.


In spring, you may start to notice small golf ball sized nests. These are what we call starter nests. In effect this is the queen building an embryonic nest containing a series of hexagonal cells. During the early stages of life, each cell will be home to one wasp, from egg, larvae and pupa before emerging as an adult wasp.

As the nest produces more and more worker wasps, the nest will begin to grow. And that’s at a rapid rate during the summer. During the height of summer, a nest can house anywhere between 5,000 and 15,000 wasps depending on the size.

Towards the end of summer, nest growth slows as it produces more males than workers. Focus then shifts from growth, to constructing larger hexagonal pods to produce the next generation of queens for the following season.

The nest dies in winter due to combination of cold weather and lack of food. This is why wasps will always build a new nest each year.

Pest Control

The wonderful wasp - a wasp's nest

Wasps are a natural pest because of their ability to sting multiple times without dying, unlike bees. A single wasp sting, although painful, will usually result in nothing more than a bump and some pain. In worse case scenarios it can lead to severe swelling, or in some cases death caused by anaphylaxis.

This article in the Daily Mail refers to my former employer and one of their technicians unfortunate enough to die from wasps’ stings after a call-out to treat a nest. This tragic occurrence highlights the dangers of wasps when in the wrong place and why we control them.

When we attend your property to treat a nest, we’ll wear full head-to -toe protective clothing to protect ourselves from unwanted stings. We’ll then carry out a full assessment to ascertain:

  1. Where the site of the nest is and …
  2. … What hazards could arise once we treat the nest. For example, open windows, gardens in neighboring properties being in use and so on.

Once we’re happy that we’ve addressed all concerns we’ll proceed to treat the nest with our Co2 powered wasp’s nest equipment. This pushes insecticide in a powdered form deep into the nest. That action contaminates the nest, killing all wasps and grubs completely within a few days.

Where possible we can return to remove and dispose of the nest. Though that does depend on how accessible the nest is. For example, if it’s situated inside a cavity wall, then that wouldn’t be accessible.

We also offer wasp control in pubs, restaurants and hotel gardens and indeed any outside space where wasps could cause an issue.
