PROVOKE Professional Gel for Rat Traps is a food-based gel that has been specifically designed to meet the unique behavioral characteristics of rats. Since rats are driven more by scent than taste, PROVOKE for rats contains a unique blend of scents that Norway and roof rats find enticing. PROVOKE can be dispensed easily onto any rat trap via its convenient 8 oz./224g squeeze bottle. Apply it to the removable bait cup on TRAPPER T-REX Rat Snap Trap for outstanding results. Like its mouse counterpart, PROVOKE Professional Gel for Rat Traps is hypoallergenic; it can be used in sensitive areas where where food products to draw rodents to the trap, such as peanut butter, are prohibited. It is also water soluble so it won't stain clothing or carpet.
