Smelly Jelly Scents are some of the most popular fish attractants on the market today. The Smelly Jelly Pro Guide Formula has taken the essence of each forage species and concentrated it, then they mixed it in a jelly base. This larger 4oz jar is perfect for guides or anglers who are on the water a lot. We like to get a hobby brush with stiff bristles to apply to the lure or bait. The jelly will stick to whatever you apply it to and last. The Pro Guide Formula comes in a large four-ounce jar. You can use Smelly Jelly to mask your scent after handling lures and as an attractant to bring fish to the bait. When they bite, the natural flavor will make them hold on longer. The Pro Guide Formula scents work for all game fish.
