This is one 16 oz. bottle of Crayster Crawfish Attractant and is made to add to your crawfishing bait. It can improve your wild crawfishing catch up to 50% or more. This is the first attractant to specifically target crawfish. The Crayster Crawfishing team in conjunction with Pro-Cure developed this potent crawfishing formula. It includes Salmon egg oil, trout, bioluminescence, strike attractant, special oils to keep the scent on the bait and not floating to the top and much more. First shake to mix together all contents thoroughly. Then, the very best way to use it is add a squirt to your bait (Oily fish, preferred) and let it soak in for 1 to 12 hours. Use the more powerful bait to catch crawfish faster and improve your yield on longer soaks. One bottle should last many crawfishing trips.
