In Australia, paper wasps are common backyard insects known for building small, umbrella-shaped nests under eaves, roofs, and tree branches. These wasps can become aggressive if their nest is disturbed, and their stings are painful, sometimes causing allergic reactions. While they help control garden pests, nests close to homes pose a safety risk. Regular property inspections, sealing entry points, and professional pest control are the most effective ways to prevent paper wasp infestations.
