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

Hoe om dit te herken

A dark, robust spider. Females have a body up to 18 mm long and a leg span of 30 mm.1
Males are smaller, about 10 mm long, with longer legs in proportion to their body.1
The body and legs are dark brown to black. The abdomen (rear part) is charcoal grey, with light markings that are sometimes faint, and it is covered in fine, velvety hair.1
The web looks messy, with irregular sail-like sheets of silk and a funnel-shaped retreat, usually in the middle or corner of the web.1

Word dikwels verwar met: The grey house spider (Badumna longinqua) is similar and has a similar range. It is slightly smaller, at about 14 mm, has a greyish top section (carapace) and black-brown legs. It is more often found outdoors.1

As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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

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

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

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

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

Mite: Black house spiders are dangerous spiders.
