SAC
Sac spiders are yellowish with a black head. It is an aggressive spider and is responsible for most spider bites in South Africa. They are notorious for the nasty bite they give, and most bites occur during the night when an unsuspecting victim rolls over on a roaming spider. Sac spiders have cytotoxic venom – the bite is painless and looks like a mosquito bite. After a few days it is swollen and painful and eventually forms a large lesion. No anti-venom is available, but antibiotics are needed to treat the lesion and prevent infection and tissue damage. The wound can take up to four weeks to heal, but in severe cases it can take up to a decade for the area to recover. Hospitalisation is not necessary, but plastic surgery is sometimes needed to remove damaged tissue.
