The Truth About White Tail Spiders in Midland

February 08, 20262 min read

White-tailed spiders have a notorious reputation in Australia as venomous biters. But the truth is much less sensational. They are important, beneficial predators of other spiders and seldom cause harm to people or pets.

Identifying White Tail Spiders

White-tail spiders are dark reddish-grey or plum to almost black in colour and have a slender, cigar-shaped body. There is a prominent white mark on the tip of the abdomen. Females are 18mm, and males are 12mm. They are opportunistic hunters and forage at night for prey such as curtain-web spiders, daddy-long-legs (Cellar spider), redback spiders, and black house spiders.

These spiders are widespread and found beneath bark, rocks, leaf litter, logs or in urban habitats such as gardens, sheds and occasionally within houses. They have a fearsome reputation but tend to stay away from humans and only bite if they are annoyed.

Are White-Tailed Spiders Dangerous?

White-tailed spiders are not considered to be dangerously poisonous. Their bites may cause:

  • Immediate burning sensation

  • Mild swelling

  • Red, itchy mark

No proven association exists between white tail spider bites and ulceration or necrotic skin lesions. Basic first aid, including cleaning the bite and applying a cold compress, usually heals most bites within days. Anaphylaxis is a rare but serious allergic response and needs immediate medical treatment.

Bites from animals such as dogs and cats generally are mild, resulting in no lasting damage, though the victim experiences some pain. Consideration should be taken to observe your animals and consult with a veterinarian if clinical signs persist.

Behaviour and Habitat

The white-tailed spider is a night hunting spider which feeds primarily on other spiders. They like dark, moist places and are active in warmer months, which can lead to them venturing into your house. Young may feed on the same bush of their mother for protection and until they grow up.

Preventing and Controlling White Tail Spiders

To avoid coming into contact with white-tailed spiders:

  • Caulk or weatherstrip doors and windows to seal gaps between openings.

  • Clear away clutter, leaf litter and logs near your house

  • Keep spaces clean inside, including shoes and clothing.

  • Natural repellents such as peppermint or citrus oils

In case of heavy or long-standing infestations, professional pest control may be required.

Conclusion
White-tailed spiders are much maligned little creatures. They are not fatally harmful, help control other spider populations, and can live safely with humans. With good home hygiene and professional pest control when necessary, you can have a spider-free, safe Midland home.
