Although spider bite symptoms are well documented, spiders are commonly blamed for “bites” that are nothing to do with spiders. One of the problems when dealing with a bite is that the culprit is rarely seen. Each of the medically important spiders display characteristic symptoms which can be used to identify the culprit. The following illustrates the genral symptoms for each of southern Africa’s medically important spiders. [teaser img=””]

Bites by the Black Button Spider are more serious than the Brown Button Spider. Their bite can cause serious neurotoxic symptoms in a short period of time. Antivenom is available for the treatment of Button Spider bites.
Sac Spider venom is cell destroying causing a lesion and tissue damage. Large fangs and the depth at which the venom is injected cause very different symptoms compared to the Violin Spider. Bites often occur at night while the patient is asleep. Sac Spiders are blamed for a lot of bites that are nothing to do with spiders.
Violin Spiders has a mythical reputation bordering on mass hysteria. The venom is tissue destroying, causing a lesion to develop. In most cases the bite will heal by itself without any medical intervention. Reports of this spider causing massive tissue damage are hoaxes. The bite symptoms from a Violin Spider are very different compared to the Sac Spider.
The symptoms of a Six -eyed Sand Spider bite is only understood from research on rabbits. Medical research suggests that these spiders are highly venomous. To date there have been no verified bites from this spider so the effect of their venom is not fully understood in humans.
