The most likely time for people to encounter snakes in their garden is spring when snakes are becoming more active.
If you see a snake in your garden or house, do not try to catch or kill the snake. Walk away slowly and keep an eye on the snake from a safe distance (several metres away). Keep your pets safely away from the snake, who will usually move on in their own time. Snakes don’t want to be near humans any more than humans generally want to be near snakes.
If the snake has decided to stay around, and you really want the snake removed from your property, you will need to contact a licensed snake handler to have the snake removed. If the snake is inside the house, close the door of the room the snake is in and place a towel under the door to prevent the snake from exiting before you call.
Snakes play a very important role in the Australian environment and are protected under environmental legislation, so you should not attempt to remove them yourself and you should never harm a snake. Most people who get bitten by snakes do so when attempting to remove them.
