If you do decide to look for it and want to pick it up, you should wear gardening gloves (they do bite out of self defense and, although not dangerous, can be a right pain to get off!)
However if you cannot 100% ID the snake I would not attempt to pick it up, as there is alwas that tiny chance. It's probably on the hunt right now- this is the best time of night to find the rodents (sometimes birds and amphibians) the feed on.
