Odd, I was JUST thinking about that today!!! Fish is definitely the strongest, stinkiest, and easiest to use to scent anything with. But I find that worms when chopped up put a coating on anything that, while it doesn't stink to us, the snakes certainly have been fooled. I never have scented anything else with pinky fluids before because usually you are trying to convince a snake to eat pinkies, not the other way around. I don't think that it would be easy to scent a fish or a worm with pinky juices, I think the snake would still be able to smell that it is a fish or a worm. You can wash the odor from a pinky, but no matter what you do to fish, it still stinks like fish!

I have also used salamanders. They are one notch right under fish in terms of scenting power, maybe even the same. Very strong odor, very strong feeding response! Frogs are a little less enticing as opposed to the salamanders for some reason but if I had to put my own list together: my stink-o-meter would go:

1. Fish (especially rosy reds and bluegills)
2. salamanders
3. frogs
4. worms
5. pinkies
