Wasp nests can be particularly annoying when they are close to people. Not only do you have to deal with the increased number of wasps in the garden and in the house - the nest constructions can also damage the house or shed to a certain extent.
Wasps can still be persuaded to nest elsewhere
It becomes particularly problematic when:
- there is an acute danger from the proximity of wasps (e.g. due to insect venom allergy or small children in the household)
- the roller shutter function is impaired by the nest created in the box
Once a colony of wasps has settled in the attic, in the garden shed (€24.90) or in the roller shutter box, it is difficult to get rid of them. In order not to expose yourself and the animals to unnecessary stress, it is usually best to simply tolerate the wasp colony. After all, wasps only have a short life, so after half a year the spook is over anyway.
However, in order to avoid being accompanied by wasps for a summer, it is advisable to prevent nest building in good time. First of all, it is important to know which places in and around the house are particularly popular with the social, social and most problematic wasp species. In contrast to most other, less well-known wasp species, German and common wasps or hornets do want to be close to humans. For example, they like to build their nests
- In roof trusses
- In roller shutter boxes
- In a garden shed
- In cavities between walls and outer cladding
In such places, the animals seek out overhead corners and niches that are dark and sheltered. What you can do to make it as uninviting as possible for the wasps is the following:
- Minimize access
- Set up odor barriers
Minimize access
In the case of roof trusses and roller shutter boxes, the main aim is to block or reduce access. Check the roof of your house for any gaps and openings that can be caused by porous insulation material or irregular roof tiles, for example. Such vulnerabilities provide wasps with easy access to suitable nesting sites.
You should check window frames and the outer cladding of roller shutter boxes for cracks in the outer plaster and seal them.
In the case of cavities between the facade and the foundation wall, unfortunately not everything can be closed, because a ventilation duct is usually required here.
Deterred by smells
You can also rely on the wasps' fine sense of smell to prevent nest building. They can't stand some smells at all and won't settle down where it stinks. What they don't like at all, for example, are ethereal-herbal smells. It is recommended, for example, to rub the beams in the attic with lavender, clove or basil oil. Garlic cloves laid out are also effective. For example, a strong-smelling frankincense plant can be hung up in the hanging basket on the window and the outside facade.
Old wasp nests should also be removed in autumn and the area thoroughly cleaned - the familiar scent of the conspecifics can invite other young queens to settle down the following year.
