The more I think about it, I wonder if using rubber gloves might work, since any venom that a hognose has actually must trickle down the outside of their enlarged teeth- so in other words, it's not really injected the way that rattlesnakes & cobras & such do. I would try the gloves if I were you (OP), & have
them fitting fairly snug so you don't lose the snake with a poor grip: I think you might still be able to feel the tip of their teeth thru the rubber glove, but
I have a feeling that any venom would stay on the outside of the glove. And I don't think that the taste of a rubber glove will appeal to a snake that's hungry anyway...but you never know I guess? Maybe if he tries it he'll decide they taste awful & learn?
