The "magic potion" consists of Golden Malrin (fly bait) and cola. It looks like blue pop rocks. Use with caution as it drops varmits within inches of the pan. To make sure it only gets hard to get nasties, put it in an old bird cage on its side and cover it up during the day so it is only available from about 11p.m. until 6 a.m. Any farm store has it but they are not allowed to tell you how to use it off label. I have always resisted using it, but it became an evil necessity this year. I still miss my Mama Hen who was sitting on a perch in her own barn that I had all the doors closed up and had just put the hardware cloth up over the one door opening because it was so beastly hot. When I got to the barn at 6 in the morning to find pieces of Mama and her babies hanging on the 8 ft high fence, I pulled out all the stops. I have been criticized at work for not "rehoming" all the thieving critters, but it is illegal to dump off trapped predators because of possible disease and it just isn't nice to give the problem to someone else! As others have found, they get wise to the live traps. A trapper in our area has advised of all the methods and has helped me learn how to properly set and disguise traps but some crafty coon avoid them all. Good luck - I set live traps every night around my barn just in case something else decides to wander in......
