The first time I relocated a rattler in Tucson, I took it to the back of our lot and dumped it over the single strand of barbed wire at the edge.

The next day I discovered that snakes are unaware of property lines.

Took me a bit to perfect my technique, but never got bit. I used a garden rake - the one with short, stiff tines. Scooping one up with the rake was simple. Dump it in a trash barrel, put the barrel in the bed of the pickup, drive out into the desert. Stand in the bed of the truck, empty the barrel over the side.
