The bite of a white-tail spider may cause nausea and burning pain followed by swelling and itchiness around the site of the bite.
In some rare but dramatic cases, a severe allergic reaction, blistering or ulceration of the skin, similar to gangrene, has been reported in the media and linked to the bite of a white-tail spider. However, this cause/effect relationship has not been proven conclusively to the satisfaction of some scientific researchers. Bacterial infection of the wound caused by Mycobacterium ulcerans carried on the fangs of the white-tail spider, may be a contributory factor. In any case, first aid and medical attention should be sought, if bitten, as and when any adverse health effects are observed.
