What are the five most dangerous spiders in Australia?

Australia is home to some of the world's most venomous spiders. While fatalities are rare due to the availability of antivenom, their bites can still cause serious medical issues. Here are the five most dangerous spiders in Australia:

1. Sydney Funnel-Web Spider (Atrax robustus)

Considered the most dangerous spider in Australia, the Sydney Funnel-Web has highly toxic venom that can affect the nervous system. Males are more venomous than females, and their bites can cause severe pain, muscle spasms, difficulty breathing, and even death without medical treatment. They are found in moist, sheltered environments such as gardens and burrows.

2. Redback Spider (Latrodectus hasselti)

The Redback Spider, closely related to the Black Widow, is identifiable by its black body and distinctive red stripe. Their venom contains neurotoxins that cause severe pain, sweating, nausea, and muscle weakness. Redbacks are commonly found in dry, sheltered areas like sheds, outdoor furniture, and under eaves.

3. Mouse Spider (Missulena spp.)

Mouse Spiders are often mistaken for Funnel-Webs due to their similar appearance. They are aggressive and possess potent venom, though bites are rare. Found near rivers, burrows, and gardens, they are most active after rain.

4. White-Tailed Spider (Lampona cylindrata)

White-Tailed Spiders are feared for allegedly causing necrotic ulcers, but this is debated. Their bites can lead to pain, redness, and swelling. They are commonly found in homes, hiding in clothing, bedding, and dark corners.

5. Trapdoor Spider (Idiopidae family)

Trapdoor Spiders are often confused with Funnel-Webs but are less venomous. However, their bites can cause local pain and swelling. They burrow underground and are mostly active at night.

Spider Bite Safety

If bitten by any of these spiders, seek medical attention immediately. For funnel-web bites, apply a pressure bandage and keep the limb immobilized until help arrives. Visit https://www.flick.com.au/blog/the-5-most-dangerous-spiders-of-australia/ to know more.
