These dark grey spiders are 12-17mm long and readily recognised by their elongate body form and a distinctive white patch on the end of the abdomen. Pale patches are present on the sides of the abdomen in juveniles but these fade in adults.
Although white-tailed spiders are not considered poisonous to humans, their bite can cause pain, swelling, itchiness and general irritation. Medical treatment should be sought as there can also be longer-lasting effects if there has been a transfer of bacteria, or if the wound is not treated appropriately.
Contact your local pest control provider for advice on controlling white-tailed spiders in the home.
