Combine the 3 things it probably wants most... Security, warmth, and food

Take a board or plastib bin lid or something flat and lay it on the ground next to the hole + snake. Prop it up on one end with a book or something just big enough for the snake to crawl under - but still cozy and dark. Have a heat pad on the flat board thing to create warmth. Then put your rodent in a box with holes on top of the board.
