Mini marshmallows. Works - they must love marshmallows in this area. We’ve tried cat food (wet and smelly) but it was messy. Never tried hard boiled eggs though, but that would seem like an easy idea too, and smelly enough for the raccoons to be aware of the bait.
Now I'm totally getting a package of marshmallows to give to our squirrels to see if they like them, lol...then again I don't want to attract raccoons.
