So far, the easiest solution for me has been to keep hides that kan be moved with the snake in it.

I'm considering trying two other possibilities myself; A hide that can be closed from the outside (something like the kind some people use with venomous snakes) and another one that's similar to what Dan suggested. I've seen some professionals use something similar. A sack with a short PVC pipe in the opening, the idea being that when disturbed, the snake would head towards the nearest hole and move into it voluntarily.
