Everyone has tried most things on baits. Ask the people who catch fish what they actually put on their baits. Nothing. You can make an argument for fish such as catfish who'll often catch their fish based on the most putrid , smelly bait they can find. That's how they eat...some don't even bother to use a hook....the fish will hang on because of that wonderful, oh so disgusting smell.
No, I don't use attractants. Ever.
