Paper wasps are a social wasp consisting of small colonies of 12-20 individuals.
Adult wasps feed on nectar and make paper nests mixing saliva and wood fibers, they have beneficial value as predators of pest caterpillars, however they have a painful sting and will attack any person approaching or disturbing their nest.
Nests likely to be disturbed represent a hazard and should be avoided during the day.
Ignore nests where they are high and otherwise out of the way.
Nests in high traffic areas such as doorways, pergolas, or carports can be sprayed from the side in late afternoon or early evening when wasps have returned to the nest, with a registered wasp insecticide.
What you can do
Wasps are quite dangerous when the nest is disturbed, a qualified technician is highly recommended.
