A wasp nest can be dangerous, but it doesn't have to be
Whether a wasp's nest is dangerous or not depends on the location of the nest and behavior of people in the area. There are situations in which they can become a real hazard. However in many cases, peaceful coexistence is feasible as wasps only really attack when they feel threatened or their nest is at risk.
With lots of wasp species, as long as you keep a distance of two meters from the nest, then the wasps shouldn't really be a problem. An exception to this are the German and common wasps because they like the smells of our meat and sugary foods. If the position of the wasp's nest allows, an opened privacy screen (sheets, awning) can help to keep wasps away.
