Green Tree Snakes

I have had the occasional visit from these snakes in my house. Once one slithered over my arm while I was sleeping, I thought it was a lizard running over my arm but when I came to my senses I got a little suspicious and turned on the lights only to find a snake slithering away from my bed! The next 10 minutes were spent watching each other from opposite sides of the room until I managed to make a plan. Finally I opened a window close to the snake, tickled it's nose with a broom and it finally left me for the outside world. Green tree snakes of this variety are not poisonous but will bite if threatened. The red tailed variety however are more dangerous. Back in 1988 I often had cobras hanging on my shower head and dealt with them by hurling a broom at them and making a run for it. Worked every time but has left me with a habit of opening bathroom and toilet doors and taking a good look around before entering!
