If you want a wild snake then boards, tin and carpet laid out near fence lines and tree lines will attract snakes. Two problems 1. it is actually littering to lay these out and 2. It takes about 6 months to get good under a piece of AC. I fell in love with snakes more in hunting them then in owning them. If you pay attention you can learn a lot by field herping.
Before I got serious about field herping I used newspaper and carpet for cage liners. After awhile I noticed that I never found a snake under a piece of newspaper in the wild
so I switched to aspen. The carpet being a terrible choice for many reasons. Then after awhile more I switched to cypress mulch and branches and leaf litter in my cages and I saw the wild snakes I fell in love with. They would investigate their cage when i put in new leaf litter, just like the few times I saw a wild snake that didn't see me. The wild snakes would smell every piece of its surroundings and pick its path carefully as it crawled through the bushes in such a beautiful way.
The point is, if you want a WC black rat then go catch one. In doing so you could, if you pay attention, learn about the snake. At the very least you will likely appreciate it more than you would a $20 snake.
I try to take the little money I make each year to take a trip somewhere with the express point of snake hunting. In the last two years i got a alterna and a pyro on these trips and it only cost me about $1,200 per snake.


I did spend the time between trips planning and learning about where i was going and in the process i learned more about my animals homes.
So not all field herping is bad for the hobby as some may want you to believe. Just try to learn about the ecology of the area that you are taking the snake from and it will not be a waste. The science community would like you to forget that they kill the animals they study (some of the time), and have more than one, one of a kind animal in a jar.
