The cupboard spider is a common house spider that lives in dark corners and builds messy, three-dimensional webs. It is often mistaken for the dangerous black widow, but its bite is usually minor. Its name shows that it is found in many parts of the world, including Europe, temperate Asia and areas where it has been introduced.1

The spider is not aggressive. Most injuries to people happen when a spider is accidentally squeezed or pinched and bites in defence. It is possible that a spider may bite a finger pushed into its web by mistake.1

It usually flees when a large creature comes near, and it bites when it is squeezed or pinched.1

It can go several months without feeding, as long as it has access to water.1

Females can live up to six years, while males typically live 1 to 1.5 years and often die shortly after mating.1
