The Aussie White-tailed spider (relevant Australian species are Lampona cylindrata and Lampona murina) is native to Australia and was introduced in New Zealand and became widespread throughout the North and South Islands since 1980. It is a common Australian spider, especially numerous in the Central Coast and Port Macquarie Region. Interestingly, White-tailed Spiders attract interest due to myths about their bites, but they are not as dangerous as commonly believed.
Where does the Aussie White-tailed spider live
In the outdoors, white tails are mostly found under logs, bark and leaf litter. In searching for their spider prey, they often venture into homes where they can end up between linen, towels and in shoes, thereby potentially coming into contact with humans
What do they eat
White tailed spiders are nomadic vagrant spiders (non webbing) that actively search and predate on other spiders including their own kind. Preferred prey is webbing spiders such as Black-house, Curtain-web and Red-back spiders. Prey is predominantly hunted at night and when caught they subdue the prey by injecting venom through their fangs.
Are they dangerous?
These spiders have a really bad reputation that is not warranted. Terrible stories abound of necrotic symptoms and limbs being amputated after being bitten by white tails. This all started around the 1980's and was fueled by myths and misinformation. In effect, white tails are not aggressive and only mildly venomous. Too date there have been no human fatalities directly linked to White tail spider bites. Most bites happen accidentally when they are startled, and the bite is usually no more painfull than a bee sting. Bites typically cause localised redness, itchiness and mild swelling with most of the effects wearing off within 24 hours. When bitten, it's best to clean the bite site and apply a ice pack to reduce the swelling. Secondary infections can occur through excessive scratching and generally poor hygiene. Anaphylactic shock has been observed in some bite victims.
Should I keep the Aussie White-tailed spider around?
It’s generally not necessary to keep White-tailed Spiders (Lampona cylindrata and Lampona murina) around, but they do have some benefits in nature. Whether or not you should tolerate them in your home depends on your comfort level and circumstances.
White tails are beneficial to have around and should not be purposefully targeted. A regular general pest treatment of your home will take care of their spider prey and in so doing limit the White tail's need to enter your home. Keeping the outside walls of your home clear of encroaching vegetation will also help to keep them away.
