My brother was in pest control for awhile in the past.
He used to tell me how his day went (not that that is important

) but he used to say that whenever he went to a job and was trying to catch racoons / muskrats that he would use apples as an easy alternative. He said that those "kinds of animals" were more sight oriented and it was important that it looked appealing to them, rather than the "peanut butter" glue traps that would attract regular rodents / mice and only had to smell a certain way.
Hope that helps......I guess I'd cut up a 1/2 apple and give it a shot.....save the other 1/2 for lunch
