I'd ditch the sticky analog thermometer/humidity meter and get a digital one like an Accurite. I find the sticky ones were very inaccurate in measuring temps.

Also you NEED a thermostat for your UTH as it can get way too hot: hot enough to cause serious burns to your snake. I use the VE-200, but since you only have one snake I know a lot of people recommend the Hydrofarm thermostat on Amazon (roughly $30). I'd get a lamp dimmer in the meantime so it doesn't overheat or simply unplug it if your temps are staying right.
