The Australian Paper wasp is a common wasp species that inhabits homes, gardens and bushlands. One of the roughly 12,000 wasp species in Australia, Paper wasps play an important role as pollinator in the Australian ecosystem.
Paper wasps are native to Australia and are distinguished by their inverted cone-shaped nests, found under the eaves of houses and in trees.
Unlike bees, wasps can issue multiple painful stings at any one time. Wasps will aggressively swarm and attack if their nest is threatened. Paper wasps can give a painful sting and some people can respond with a severe allergic reaction.

Australian Paper wasps have a reddish brown body with some yellow or orange bands.
Likewise, they have a slender build, narrow waist, and tend to range from 10 - 15 mm long.
They are commonly misidentified for Asian Paper wasps.
However, Australian Paper wasps tend to be smaller than their Asian counterpart and have less distinct banding.
Paper wasps live in heathlands, urban areas, and forests and woodlands throughout Australia, including:
Paper wasps spend their time building nests from wood fibres mixed with their saliva - which form a type of “paper”. A Paper wasp nest is an ingenious piece of organic architecture made of hexagonal cells that form a comb.
These cells hang in an upside-down cone-like structure from a stalk of pulp, often high in a tree or a house eave.
Adult Paper wasps eat nectar, though they collect caterpillars to feed their larvae.
As such, they play an important part of pollinating along with keeping garden insects under control.
Paper wasps are not as aggressive as their European counterparts, however, they can be aggressive when defending their nests. There are more than 35 species of native Paper wasp, and each has a distinctive nest design.
Paper wasps are not venomous but will give a nasty sting if their nest is threatened. They attack as a swarm, and as Paper wasps give multiple stings it is important to exercise caution if you come across a nest.
Paper wasps are an important part of the native ecosystem, they are not considered a pest, but are more likely to keep other small annoying insects at bay.

Care and treatment for a wasp sting goes like so:
