We did try tuna and canned cat food and I don't know how many other things. I think bought marshmallows but that was about the time we caught the first one or this one previously if it found it's way back.
I sent my husband out for more tuna a few nights ago and he did a smart thing. It didn't catch the raccoon but it kept the cats/kittens from eating the food up. He just stabbed the can. It is open enough that the smell can float out but if a cat or kitten gets caught in the trap trying to eat the tuna, they can't get it.
Raccoons love things sweet.
Most of the guys I know that trap for raccoons will use a number of homemade bates and some use store bought baits. They use marshmallows with jelly on them, reese cups, and honey buns.
I've caught a good number of raccoons with honey buns with a bit of sweet strawberry syrup or jelly on the middle of it, jelly filled donuts cut in half works well for me also.
If your using a cheaper all wire trap like "have a heart" you might want to make a "sleeve" for it or at least fasten it to the ground with some heavy duty tent stakes.
A sleeve is nothing more than a box that slides over the trap leaving only the door of the trap exposed.
The sleeve keeps the raccoon from trying to get the bait through the wire and nocking the trap around and tripping the trap.The sleeves I made were made out of plywood and were just big enough to slide over the trap.
I also drilled about 4 holes (the size of a 1/2 dollar) along the 2 long sides and 2 holes the same size along the back.These wholes were 2 inches down from the top and helped with letting the sent on the bait out of the now boxed in trap. One other thing, I like to set one cement block on each of the long sides to keep the raccoon from moving the trap.
