Redback Spiders
Venomous, with webs tucked into dry, sheltered spots.
- Look for
- Females are about 10 mm long and shiny black, usually with a red to orange stripe along the top of the abdomen and a red or orange hourglass underneath. Males are much smaller, at about 4 mm, and only the female's bite is dangerous.
- Found in
- Loose, untidy webs in dry, sheltered places such as sheds, rockeries, logs, shrubs and junk piles. They're especially common around homes and other built-up areas, and a web can hold up to 10 round egg sacs.
- Treatment focus
- Redback webs are easy to miss under ledges, stored items and outdoor equipment, so treatment starts with a careful search of the yard, especially where children and pets play. We remove the webs and egg sacs and treat the sheltered spots where they build.
