Brown House Spider

Badumna longinqua

The Brown House Spider is an introduced species, originally from New Zealand, that has become extremely common throughout urban Australia. It is a major nuisance pest due to the messy, tangled webs it constructs in and around buildings. These webs, which are not cleaned by the spider, quickly accumulate dust and look unsightly. They are typically found in sheltered, dry locations like window frames, corners of walls, under eaves, and on sheds. While their bite is not dangerous to humans, their sheer abundance and the persistence of their webs make them a frequent target for pest control and household cleaning.
