Like the homeowner who hires a trapper and that trapper breaks out bait and claims the reason you weren't successful was because commercial bait and lure have "special" ingredients to attract animals in them. That's always a good one and around here some pest guys who do wildlife control use that a lot. I've said to customers on more than a few occasions after the first 1 or 2 companies failed...then why am I here if they used "commercial bait and lure? Always done with a smile too, we all lose a few here and there, comes with the territory. They've paid good money for their services as well. I believe an individuals efforts and ability in "trapping" is the missing link to a lot of problems from coyotes to squirrels. You could spit on the ground and have a canine come over and give it a whiff, especially after eating a fantastic meal. When trying to make an attractant for an animal, I really believe if people put half the energy into their ability to trap an animal while learning about the target animal and things that animal likes, needs and what sparks its curiosity. As they do on trying to come up with the million dollar concoction without testing, knowing or having an idea why an ingredient is added or evaluating the materials they are using by field testing and serious about it, would put them right where they want to be, with a better understanding. You'll also find that making an attractant isn't as hard as most make it out to be. Putting on the lab coat and compounding lethal ingredients that'll knock ya out without wearing a respirator or any other crazy combo is a different story, but I've seen many guys who buy "THE BEST BAIT" use their own blend because the best bait just wasn't the best in their neck of the woods. Then I've seen lots who use the best bait and do very well, but they take their trapping very serious and practice making sets and do their homework in the field by setting where the animals are. Some will say its more scaled to that then it is the bait. Hard to get better at something or making something without practice and repetition. jmo
