Herald Snakes can often be found seeking shelter under rockeries or compost heaps in gardens. They’re especially common in marshy areas, fynbos, lowland forest, moist savannah, and grassland.
They prey mainly on toads, and when threatened they raise their flattened head horizontally whilst hissing and striking with the mouth open.
Oviparous, they lay 6-19 eggs in the summer.
Herald Snakes bite readily when threatened, but their venom is not thought to have any harmful effects on humans.
