How do you get a Corn snake out of a house?

First of all, Thank you for not panicking or killing the snake. Cornsnakes are non-venomous completely harmless snakes but they do have a look-a-like and that is the venomous copper head so make sure that the snake is a cornsnake. Don't worry if you hear rattling because cornsnakes vibrate their tail like a rattlesnake to scare away predators.

Okay, now to get rid of the snake. What you will need is a large stick or a snake pole that has a non-sharp hook on it and a thick pillow case that you can throw away afterwards. If the snake is bunched up in a corner then straighten it's body out with the stick, if the snake is aggressive then use the stick to pick it up, if he is pretty calm then gently pick up his tail and hold it in your hands. Get a friend to hold the pillow case on the ground in front of the snake and he should slither into it. If he is aggressive and you are using the stick to pick him up then shove him into the pillow case and he should slither off of the stick and settle in the pillow case. Make sure that the snake is at the bottom of the pillow case and then tie a knot so he cannot escape. Next relocate him in some nearby woods or at the place where woods and a meadow or field meet. He should just slither Into the Woods and not bother you.

If you don't feel comfortable getting the snake out your self then call an exterminator to get him in the pillow case for you and then relocate him your self. Good luck!
