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

Če ugrizne

Ugriz umij in nanj daj ledeni obkladek proti bolečini. Poišči zdravniško pomoč, če je bolečina močna, se širi ali se poškodovanec slabo počuti.

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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
