When an earth wasp nest in the garden becomes critical
In our latitudes, earth wasps are usually German or common wasps who have chosen a place in the earth to found their state. This can be an abandoned mouse or mole burrow, for example. In principle, the named wasp species can also use places higher up such as roof trusses or garage niches to build nests.

Having an entire wasp state in the garden can of course be problematic. In late summer, a wasp community grows to around 7,000 animals, many of which swarm out every day to search for food.
You should weigh carefully in advance whether you want to get involved in a clear fight. There are some reasons against it:
- Wasps are protected and cannot be easily controlled
- Control is dangerous and not necessarily animal friendly
- Wasp State only survives for a limited time anyway
Wasps are protected
First of all, it is important to know that the Federal Nature Conservation Act makes willful interference with or killing wasps a punishable offense. Under certain circumstances, such as an insect venom allergy or small children living in the household, control can be approved individually.
If possible, do not carry out wasp control yourself
Even if a wasp control is justified in your case by the nature conservation authority, you should not take appropriate measures yourself. It takes some experience with the animals and of course professional equipment to bring the whole thing over the stage as safely as possible. A beekeeper or a specialist from nature conservation associations can also better assess the situation and derive suitable options from it.
The gentlest method that specialists use to remove wasps is to relocate the nest. To do this, the animals are first put into a twilight state with an animal-friendly agent so that they do not get too stressed and understandably become aggressive. Then they are sucked alive so that the nest can be carefully dismantled. It is then rebuilt 3-4 kilometers away and the animals resettled. From this distance they cannot find their way back to their original location.
Passive methods of eviction
When it comes to contact with wasps, calm, passive behavior is generally best. If wasps have nested with you, you should therefore tolerate them as much as possible and use gentle measures to drive them away.
Gentle and completely unpunished options are odor-intensive plants that smell unpleasant for wasps, such as basil, lavender, lemon verbena or the frankincense plant. Rubbing lemongrass oil on patio furniture can also help. When eating at the garden table, the most important, albeit annoying, measure is not to let tempting scent molecules get into the air by consistently covering the food.
