How do you tell if the thermacell pads are done. I noticed they turn white on some areas but stay blue for the most of the pad.
DO they just stop smelling or what.

It will turn a white color. kind of a light sky blue.

The mosquitos will let you know. [8D]The pad will start to turn light blue to white when they are about done

will it turn the entire pad white or just spots. i think i might be wasteing it but the box says three hours surely i ran them that long.

The entire pad will turn white. I just threw one away after about 6 hours of use.

well y does the back side stay dark blue?? that confuses my i mean is it just the dye or is that some ive been waisting?

Man no kiidding. LOL

sounds like i have thrown 20 bucks away in a month. I guest i will start using them longer. what sucks is the fuel runs out at 12 hours then you buy a refill one tank three pads so you end up with more pads then you will use

I hope it doesn't smell to begin with....it says odorless![&:] But not sure, guess the skeeters will tell you that. Mine still works.

You can get refil butane cartridges by themselves. They use them for curling irons and what not. They are the same cartridge, even says Thermacell on them. Check out the area in wally world where they sell hair dryers and such and you can get 2 cartridges for like $5. I heard about this on either this forum or AT, not sure which, but I did verify that they sell the cartridges.
