If you are constantly bothered by wasps in your garden it is likely that there is a nearby nest. Or there may be a food source like rotting fruit or flesh. If they discover a food source the wasps will return to the nest and recruit others to join it.
If you are certain there is a nest you will be able to identify it's position by watching the flight direction of the wasps. The main area of activity is likely to be the location of the nest. Wasps will make nests in roof spaces, in sheds and garages . In extreme cases they may make their way into the home and have been found in cupboards.
Wasps do NOT swarm like bees. If you see a mass of insects hanging from a tree branch or on a wall this is a swarm of honey bees which are important to protect. We are members of British Beekeepers Association and are happy to deal with a swarm and relocate them.
As we are responsible for looking after and managing several bee hives, we are well aware of the difference between honey bees and wasps, and would always relocate bees.
Dealing with wasp nests can be somewhat dangerous as they can sting multiple times, not just once, like a bee. Wasps will instinctively attack anyone that ventures too near to their nest, they usually have lookout wasps near the entrance to the nest and these seem to have some kind of communication with wasps that are within the nest. When danger appears, suddenly, so do a number of wasps.
We are fully equipped with the protective clothing to eradicate wasps nests.
