The venom of many Sicariidae species is highly hemolytic and dermonecrotic, [2] capable of destroying red blood cells and causing lesions as large as 1 inch (25 mm) in diameter that take a long time to heal. Some require skin grafts and if the open wound gets infected, there can be even more serious consequences.
