Tri-Die Dust, manufactured by BASF, is a powerful broad-spectrum insecticidal dust that treats more than 29 pests including cockroaches, beetles, bees, ticks, bed bugs and fleas.

This easy to apply dust formulation has a triple action feature that serves both as a repellent with contact kill, as well as providing a residual control that lasts many months against a variety of targeted pests.

Tri-Die Dust not only provides residual control, but creates an uninhabitable environment for labeled pests for both indoor and outdoor areas.

Tools Needed

Tri-Die Dust can be applied without tools, however, a handheld pesticide duster can be used to treat hard to reach areas and make the application easier and more precise.

Applications with power duster equipment are prohibited.

How to Use

• Step 1: Determine how much Tri-Die Dust you will need to use by calculating the square footage of the treatment area. To do this, measure and multiply the area length times the width (length x width = square footage). Tri-Die is to be applied at the rate of 1 oz. per 50 sq. ft. of surface area or 1 lb. per 1,000 sq. ft. of surface area for severe infestations. Do not apply Tri-Die Dust more than once per day.
• Step 2: Pour the appropriate amount of Tri-Die Dust in a handheld duster.
• Step 3: Apply a continuous, visible film underneath and behind stairs, refrigerators, and appliances. Treat cracks, crevices, insect tunnels, and/or voids with a small amount of product, but thorough application. Areas labeled only for spot treatment per the product label instructions will need to be < 3 ft. x 3 ft. per room. Check treated areas 1 to 2 days after application to ensure complete pest elimination.
