Upgrade your metal traps with Duke Logwood Trap Dye. Trap dye turns your traps a dark color that will help in hiding your traps when set. Easily dye 1-2 dozen large traps or 2-3 dozen smaller traps. When dyeing new traps boil in a strong household degreaser or lye solution to remove oil. Simmer traps in hot water just below the boiling point. Approximately one bag is needed for every 5 gallons of water. Note: Powder turns black when added to water.
