Don't worry about the human smell on the trap. I know a lot of folks say to not touch the trap, but seriously... if that was all that it took, we wouldn't have problems with the predators. The traps we used smelled like us, and I am sure they could smell me on the bait, too. We shot raccoons in the trap, dumped the carcass out and reset the trap (without cleaning it) and would get another one the next night. They don't care about human smell and apparently don't care if there is raccoon blood in there. If it is a raccoon, reset the trap as soon as you empty it. Chances are there will be more than one.
