Thermal imaging can work, because snakes like to bask and are also often darker in color than the surrounding landscape.
If you take a temperature gun, and shoot the temperature of tan colored sand, and a dark brown log, both in the same direct sunlight, the dark brown log will have absorbed more heat than the sand, and will read hotter.
Thermal imaging of course will not be nearly as good as when it is used on heat producing mammals, however, if it is capable of seeing only a few degrees difference in temperatures, it could prove useful.
If you have a python that has been sitting in water for hours, its temperature is likely to be very close to that of the water, and that snake might be invisible to the device. However, if that snake has been basking for hours, then moves into a cooler area, there will be retained heat that will show up as a difference.
I can see thermal imaging as a very useful tool, when it is used correctly, and used to take advantage of daily temperature flux.

Water is the one thing that really confounds the camera. When the animal has been near a heat source, they show up white in this camera, when they have been cool and are introduced to a warm environment you get a sort of negative image.

I agree with John. Let them have the burm it is not the end. As long as they stop importing them their are enough in the U.S. now anyways to be bred. There is not really a good reason why they are imported other than they are cheaper. I would rather spend a little more and get a quality c/b herp then go cheaper and get something from the wild that has the potential to infect my collection if not healthy.
