I experienced this problem early on when first setting up my enclosure. In my case, half of the UTH was still attached while the half that was supposed to be against the probe (which was taped to the bottom of the outside of the tub) had sagged down. This was pretty dangerous as it could have led to excessive heating if not discovered quickly. It's a really annoying problem because some heating pads, like the Zoo Med ones, require ventilation space underneath the UTH which creates the possibility for this to happen.

I'm now using aluminum foil to tape the UTH to the bottom of the tub, which is nice because I can remove the heating pad every time I want to deep clean the tub. However, even the foil tape adhesive will eventually wear out and weaken so it needs to be re-taped every so often and checked routinely.

I think taping the thermostat probe to the UTH is better because of my experience above. That way, even if your UTH adhesive gives away, the probe is still in contact with the UTH, so there is no risk of your snake being burned by excessive heating if part of it is still attached. Also, on the note of taping probes, DO NOT put tape on the probe itself (the metal or plastic part that detects the temperature) because foil tape cools the probe and will result in inaccurate temps. Always tape the wire, not the probe.
