The black house spider is a dark, sturdy spider that lives across Australia. It was carried to New Zealand and Japan, and it often lives in homes, where it sits in a messy web in corners and near windows. It is venomous, but its bite is rarely a serious danger to people.1

Eziokwu

1

A male plucks the female's web to attract her attention before he approaches to mate. They may stay together for several days and mate several times.1

2

The spider rarely moves its web, so old webs become messy, with dust and small objects stuck in them.1

3

At night, the spider repairs and adds to its web, often by laying new silk over the old.1

4

The female almost never leaves her web unless she is forced to.1

5

Predators include the white-tailed spider, as well as parasitic wasps and flies.1
