Pro-Pest Professional Lure for Rats & Mice, Origlnal Flavor, is an aromatic blend of food-grade ingredients and oils that quickly attracts both rats & mice, including roof rats and bait & trap-shy rodents. Because this formulation does not contain peanuts, no known allergens, no pesticides or rodenticides, it can be used with confidence in sensitive accounts: in homes, schools, daycare facilities, nursing homes, hospitals, food storage and processing plants, etc. Our 32cc syringe makes it clean and easy to apply lure and fits most industry bait guns. To use, simply place 1/2 – 1 gram of Pro-Pest Rat & Mouse Lure on the trap trigger of a snap trap, center of a glue board, inside a multi-catch trap or behind the trip pan inside a live animal trap.
