What kind of tape to keep probes in place?

For the outside of the enclosure - Foil tape
NO tape should be used INside the enclosure.

Ah... good point, I was only thinking about an outside probe placement. However, I've heard of people (Admin Judy for one) using a small piece of scotch tape to secure the probe to newspaper substrate inside of the enclosure. If the snake pulls the probe up, the scotch tape will just tear the paper and won't be a danger to the snake.
