I am planning on getting a White's Tree Frog from my my local pet store. They are selling a complete setup…it includes a log, some fake branches, and a water bowl. I will be keeping it in my basement room and it is more humid than anywhere else, but it isn't the warmest place. Some websites say that the rogs need a heat lamp with a thermometer and a hygrometer(to measure the humidity). Are those things necissary? I just don't want to always be afraid the house is catching on fire from the heat lamp. Someone with experience with White's Tree Frogs please help me out.

No white's tree frogs do not need a heat bulb, as long as their cage temperature is at 70 degrees minimum. Because White's are nocturnal, a heat bulb can actually stress them out and it also dries out the tank a lot. This can be a problem when you are trying to achieve a certain humidity. I don't think everyone needs a hydrometer, just spray the tank 1-2 times a day and you'll be fine. Always make sure he has clean water in his water bowl too.
