Here in AZ we get them by the truckload every year. Okay, maybe not that many, but where my wife and I work we are "in charge" of snake removal and handle about an average of a few dozen a year at times. WDB's too. We simply relocate them (if diamonbacks) or move them a little out of the way if bulls.

Wild bullsnakes (gopher snakes) tend to be on the mild temperment side. A few though can act just outright ugly! Open-mouthed strikes and all. But for the most part even the wild caught ones can adapt fairly readily to captivity. Like all snakes, each has it's own personality.

The largest snake I have ever seen (either captive or wild) was a bullsnake getting ready to cross state road 77 here one morning on my way to work. He was easily seven feet long. Now keep in mind for a bullsnake to get that big he has been roaming around the desert here for some time as a wild critter. When I spotted him on the shoulder I quickly pulled over and ran back to 'em and he coiled slightly and simply let me pick him up and walk him safely back off the road and into the brush. No biting, hissing or anything.

We love those bulls! We have plenty of pics of them over the years that we have let go. (In AZ you cannot legally transport a species for relocation further than 1 mile from origin).

What's neat is that being a native snake like Elvis the Kingsnake we have, you don't have to mess with all of those humidity levels unlike our pythons and boas.

Hope this helps!
