RE: Bought a ThermaCell today..
The Thermacell works great for keeping away the little buggers. I do smell a slight odor but it doesn't seem to bother the deer here in Md. I think they are used to different smells due to the close proximity to humans.
I agree about the scented/repellant pads. That would make way too much sense. I haven't tried the scented pads yet.
