Hi, I recently discovered an Eastern Blue Tongue lizard is living in our tool shed, but I am not sure how long it has been there; I have been feeding it snails from my garden. I live in Qld. It refuses to leave the shed, even when I leave the door to the shed open all day; any sugestions re. how to encourage it to vacate the shed for the garden instead? As I can't always leave the shed door open.
