All of ours are protected and I generally ignore them as most are around the creek or drain having a feast of endangered Growling Grass Frogs, if one comes near the house or won't move it gets relocated to snake heaven.
We had one in the bathroom when I was doing renovations, the walls were off and he came in from under the house, my wife found him and I reckon that you probably would have heard the scream where you are, another time our fox terier brought one into the house and presented it to us in the kitchen, it was very much alive and not happy, a few character building moments that day.
And to be a sanctimonious pedant I have heard there are only two poisonous snakes in the world and I think they are both in Japan.
