If you see wasps entering and leaving a hole in the ground, a wall, roof or any other part of a building between June and November then you probably have a wasp nest. Never be tempted to block the hole up, this will make them angry and aggressive but will not kill the nest, they will find another entrance and may even come inside the house. Wasps are aggressive and will sting readily if they think the nest is in danger.
If you don’t treat a wasp nest it will eventually die out but before this happens the nest will produce approximately 100 fertile Queens that will hibernate and start nests the following year. This is when they are likely to sting people. Wasp nests can stain ceilings and even eat through them in some instances.
After treatment, removal of a wasp nest is not necessary as the nest can never be reused. If the nest is removed and foraging wasps return and do not find a nest, they will attempt to rebuild and the problem recurs, if however it has been treated and left, any returning insects would be contaminated by the insecticide. Generally, the nests are located in a cavity wall or a soffit that cannot be seen.
Apart from being unpleasant, a wasp sting can cause a severe reaction known as anaphylactic shock in some people, so it’s important not to threaten or disturb a wasp nest but instead to call in professional help.
TREATMENT – After a survey and risk assessment has been carried out, our technician will decide on the best treatment to suit your situation. Generally, this would consist of a dust treatment application which would be carried out straight away. After treatment the wasp nest would usually be destroyed within a day or two depending on the size of the nest and location. Wasp nest removal after the nest has been destroyed can also be undertaken on an additional visit if required.
