Although the bite of the White-tailed spider may cause severe inflammation it has caused, contrary to popular opinion, very few cases of severe local tissue destruction. Other causes of necrotic ulcers should be sought, especially when a spider has not been seen.
The Pressure Immobilisation Technique should NOT be used.
Other Australian Spider Bites
All other spider bites should be treated symptomatically (apply an ice or cold pack to lessen the pain).
