The Australian Paper Wasp (Polistes humulis) are defensive and not aggressive. They may swarm if provoked. Forming paper mulch pyramids often seen around pergolas and eaves typically associated with overfilled or blocked gutters. As the the damage to buildings is often classed as minor building damage and cosmetic in nature, prompt attendance is key.
High traffic areas is where confrontation may occur such as near doorways and windows. As a guide, typically a 10 -12 cm nest may have between 100-200 wasps. If left untreated the nests will continue to grow and have been recorded with 100,000 wasps.
The activity is highest from summer through to late summer.
Simply removing the nests results in the wasps returning to the site to construct again. A nest is still live and will be defended if just knocked down. Some nests are the right size and shape to occlude downpipes. Ensure the pest control cleans and clears the refuge from the building completely.

When aggressive the wasp releases a pheromone (a chemical scent) that is a call for back up to other nearby wasps.
Under the large order classification “Hymenoptera”(Greek for membraned wing) here in South Australia, the European (Vespula Germanica) most readily encountered of the Wasp species is highly aggressive. Wasps are not targeting us and avoiding antagonising the wasps and as the wasps is only interested in the food source, typically a sugar fix particularly late in the season. A wasp may travel up to 500metre from its nest in its search for food, however unlike bees typically in a more direct trajectory.
A wasp will build its nest in the ground or wall cavities typically. However there are other sites this may occur. One report of a wasp nest in a musical instrument is worth a note!
