You definitely should get a thermostat if you don't have one for that UTH. It doesn't seem like it, but it WILL get way too hot for your snake. You should never let your temps rise above 95. Heat mats can get well over 100, and have been recorded to hit 120.

Here's what I use, it's the cheapest one I've seen and works well for one snake: http://www.amazon.com/Hydrofarm-MTPR...arm+thermostat

All you do is plug the thermostat in, set the temperature you want the heat mat to be, put the thermostat probe under the warm side hide, and then plug the heat mat into the thermostat. I can post a picture of what it looks like all hooked up if that's confusing. The probe from the thermostat will turn the heat mat on and off in order to keep it at the temp you set it to.
