In Australia, spider wasps are solitary insects often seen hunting spiders in gardens, lawns, and around homes. Common signs include frequent sightings of large wasps dragging spiders or burrowing into sandy soil. They prefer warm habitats such as gardens, loose soil, wall crevices, and under outdoor structures. Although generally non-aggressive, they can deliver a painful sting if handled, so prevention includes sealing cracks, reducing spider populations, and keeping outdoor areas clean and well-maintained.
