Red Back Spiders

Red back spiders are Australia’s best known spider. Red backs are found all over Australia but are rarely found in Tasmania because it is too cold.

Identifying

Red back spiders are black to brown colour, pea shaped with a red strip on the back of its abdomen. Juvenile red backs have an elaborate pattern, including lateral stripes. The male Red back spider is tiny only about 3mm in body length. The males are not dangerous. Females are up to 12mm body length. Only female Red backs are dangerous, because the males are usually too small.

Habitats

Red back spiders will live almost anywhere. Their webs can be found in timber, logs, rocks, grass tussocks, under flower pots, garden furniture, in outside toilets, sheds and junk piles. Red back spiders are more common in spring and summer.

The female Red backs have relatively small jaws making many bites ineffective. However some bites have caused serious pain and illness, requiring antivenom.

First Aid

Pressure bandaging is not recommended, as this can aggravate the pain. Seek medical attention. Cold packs or cold water may help to relieve the pain.
