Relocation of nests of protected insect species – hornets, bumblebees, wasps and wild bees

Hornets, wasps, bumblebees and wild bees are protected. They belong to the state-forming insects and survive no more than a summer. They fulfil important functions in the natural cycle. Hornets and wasps regulate the species structure of insects, bumblebees pollinate flowers with their long proboscis that bees cannot reach, honey bees ensure a rich harvest in the orchard.

Most species are harmless and do not attack humans if they are undisturbed. Only two species of wasps are interested in sweet drinks or food.

The nests are built in natural caves (for example, woodpecker burrows) or in artificial cavities such as attics. Sometimes nesting or shutter boxes are also colonized. The nest area (about 4 meters around the nest) is defended by the insects, if necessary by stinging. The following disturbances should therefore be avoided:

• violent, fast movements
• longer adjustment of the trajectory
• Vibrations of the nest
• Manipulation of the nest or flight hole
• direct inhalation of the animals

A hornet sting is no more dangerous for normally sensitive people than a wasp sting. Outside the nest area, the animals are peaceful.

In exceptional cases: relocation of the nest

In the event of a danger to humans by the insects, an exemption for the relocation of the nest can be requested. Before thinking about relocating or removing the nest, the following measures can help:

• Separating the nest in the attic with a thin-meshed net v
• Closure of the nest area with a fence at a distance of about 5 meters
• Attaching a screen

Hint: You can also find advice on site at nature conservation associations, beekeepers or the fire brigade.
