When I called in to purchase the trap, I specifically asked if I could use the product in an attic. The salesman advised that yes I could. I did not want an odor as this is a business building. I received the traps and not only did they have a terrible odor but the instructions indicated NOT to use them under a roof!! This sole reason I purchased 10 traps (at $15 each!) was to use them in the attic of our building. I do not know if the product works as I was not able to use them.
I am not really able to rate this product. Make sure to keep away from curious dogs. The very first day it was up one of the dogs jumped up and knocked it down and destroyed it :( not sure if it was the smell of it or what drew a normally non destructive dog to do that. it was placed atop a 6' pole.
