sticky thermometers are pretty useless
If they are on the outside of the tank, then the floor on the inside of it is probably warmer than they show. Best is to get a couple cheap little round ones and just lay them on the floor of the cage. Since that's where your snake is most of the time, that's where the temp should be measured.
The ones I have I got for about $2.50(u.s.) each.
