Marshmallows make a good bait for raccoons. Again, put a few outside and the rest in the trap. I have had raccoon problems in 4 different states. They thrive around humans and increase their populations. AT the first sign of raccoons checking the outer rows of corn to see if it is ready, I tied my dogs around the garden, EVERY NIGHT BEFORE SUNSET. At times with a big sweet corn patch I've tied 3 out there on different sides of the garden. It must just be the smell and noise and activity of the dogs that keeps the coons away. I have never had coon problems after the dogs started their nighttime watch. I'm sure they aren't very happy with me for doing it, especially during a rainy night, but they come willingly. Border collies usually. I don't put the little rat terrier out there. I'm afraid she could become raccoon food. Good luck. I know what you are going thru. BTW, some say electric fence works, usually at the top and bottom of woven wire or 2X4 fence.
