Scarlet snakes are terrestrial, nocturnal snakes that spend much of their time underground. They prefer sandy habitats with loose soil for burrowing, emerging at night to hunt lizards, smaller snakes, eggs, and rodents. When threatened, scarlet snakes may vibrate their tails rapidly, releasing a pungent musk. This serves to startle predators while allowing the snake to retreat underground.
Scarletsnakes are not aggressive, preferring to hide or flee from threats. They rarely bite even when handled. The docile nature, small size, and bright colors have made scarlet-snakes popular as pets, though they are better left in the wild.
