Common kraits are nocturnal hunters known for their sluggish docility during the day and active nocturnal hunting routines. They feed predominantly on other snakes, trailing scent marks through leaf litter and frequently entering human dwellings in search of shelter or prey. Their bites are notoriously painless yet deliver a potent neurotoxin, making them one of the most medically significant snakes in South Asia.
