Query: I havent caught a thing with it so far

I read the reviews and most everyone seem to have no problem with catching many squrriels, with peanut butter on a cracker stuck to the tray. But i am begining to wonder if they smell the human scent and dont come near it. Or maybe they hid it under something that masked the human scent and the trap itsefl. Has anyone got any ideas?
