Do you know how he is getting in? Snakes are the worst! I have been known to hack them with a hoe or a shovel or cut their heads off with long handled pruning loppers. Hubs is a little more tolerant so he made a pretty good snake catcher.
To make it, you need a piece of 3/4" pvc pipe about 5' long and 16-17' of a heavy wire. (ours is an old phone cord, the kind that plugs from the phone to the wall) Fold the wire in half and thread it through the pipe until you have an 8" loop at the business end, leaving 1-2 feet of the cut ends at the other end. Tie a good tight knot in the cut ends about 4" from the end of the pipe. This keeps it from getting pulled all the way through if the snake decides to fight it. When you see the snake, put the loop around his neck (well, behind his head somewhere) and pull the cut ends until it tightens. You can use the tool to pick him up and put him in a bucket with a lid. After he's in there you loosen the wire from his neck, put the lid on, and relocate him.
There is not enough money in the world to get me to reach in and grab one! Ewwww!
Good luck!
