Flooded burrows and swollen streams push snakes and their prey towards higher, drier ground.

During the south-west and north-east monsoons, heavy rain fills the burrows and crevices where snakes shelter. Rats and frogs also move to drier ground, and snakes follow them, which often brings them into gardens, store rooms and houses.

Check shoes, piles of clothing and dark corners before reaching in, and keep doors closed or screened at night. Clear leaf litter and stacked materials from around the house so snakes have fewer places to hide.

If you find a snake indoors, move people and pets out of the room, close the door if it is safe to do so and watch where the snake goes from a distance while you contact a rescuer.

Bitten by a snake? Keep calm, keep still and go to the nearest hospital immediately. Call 1990 for an ambulance.
