I wouldn't use either of those types of tape. The adhesive is strong enough to remove skin from your snake. Duct tape will likely result in death or at least permanent disfigurement, in most cases.
Instead, use 3M Blue Painter's Tape. It is a low adhesive tape that will stick to your snake and stop him from crawling, but won't remove skin. A little bit of mineral oil will loosen any extra adhesive, and get your snake un-stuck with no trouble.
Minerla OIL, not Mineral Spirits. Baby oil will work, too...
