This is a hot dip. The red powder turns black in water, and is made from log wood extract. This dyes the traps a deep blue/black color. It comes sealed in a 1 pound bag.
Directions: Degrease and rinse traps. Use 1 bag for each 5 gallons of water. Simmer in hot water (just below boiling point) with dye for approx 1 hour.
