PT Tri-Die Pressurized Dust, manufactured by BASF, provides 3 types of defense against pests. It combines pyrethrin, piperonyl butoxide, and silica dust to create a quick and potent knockdown with a long-term residual effect.
Each can come with a unique 4-way straw applicator that delivers 360-degree coverage in places where bed bugs and roaches like to hide, such as wall voids, window seals, and furniture.
Insects that are missed by the initial contact of PT Tri-Die Pressurized Dust eventually make contact with the residual dust barrier, which causes them to dry out and die. Tri-Die Dust is a powerful insecticide that will definitely take down the toughest of insects and is perfect for most insecticide treatment programs.
Tools Needed
Every can comes with a straw applicator and requires no additional tools for application.
How to Use
- Step 1: Identify target pests and the area needing treatment
- Step 2: Insert the straw applicator into the PT Tri-Die Pressurized Dust can.
- Step 3: Spray the targeted area according to the product label instructions.
Where to Use

This product can also be sprayed under appliances, in crawl spaces, and in attics.
It can also be used in transportation equipment such as buses, boats, ships, and trains.
For outdoor use, this product can be applied in cracks and crevices around patios, foundations, porches, doors, windows, and other entry points where insects can get inside. However, it is not recommended to apply near crops and water sources inhabited and shared by wildlife.

Apply as a preventative treatment plan, using the spray's residual effect. It can be used as a direct spray to kill on contact or as a repellent to ensure other pests stay away.
