Dog foodworks great along with honey and bacon grease burns , you can also use sterno cans , just as you know be careful and dont leave the thing burning. I do real well with pastries and molasses from the local feed store . I also use anis liquid smoke and vanila for some good smells. My bait has been out 2 days and is getting hit pretty good .
Oh yeah , anything will work but the sweeter the better once them berries go away they really start coming in and will hang tight around baits you often will bump them off the bait and they will be back soon after you leave , or your partner leaves .
