What should i do to attract some wild snakes close to the house.?

Not one decent answer so far.

Snakes look for two things: food and shelter. There's not much you can do about the food part, but you can provide a nice shelter habitat that may attract snakes.

First off, locate an area with a decent amount of food supply. A field would be perfect as they usually have plenty of mice, but an area close to a water source should work as well.

After you find a nice location, go out and get several clay roofing tiles. The kind that are in the shape of a half-pipe. Place a couple of them end to end or even a second pair right next to each other and cover them with large river rocks about the size of a large grapefruit. You want to creat an environment that is easy to enter, yet will make them feel secure.

Good luck!
