How To

Prescription Treatment Tri- Die pressurized dust offers a convenient, easy application with no additional equipment necessary. Pressurized, charged particles penetrate deep into cracks, crevices, wall and ceiling voids to provide an ideal uniform dust application, readily adhering to all surfaces. The unique 4-way red application straw can be used for void space application to deliver 360-degree coverage. Tri-Die is manufactured with Whitmire MicroGen's innovative MicroPro technology. Tri-Die offers three way insect control - contact, repellency, and residual effect. When an insect crosses through an application area the dust is attracted to the insect's oily or waxy outer cuticle and the insect loses body moisture and dies. The naturally derived active ingredient in Tri-Die creates an unsuitable environment for insect pests. Tri-Die is available in a convenient 8 ounce can making it easier to use in confined spaces and easier to store.
