Yes, PT Fendona Pressurized Insecticide is a knockdown kill and maintenance aerosol that is labeled for many insects including German Roaches. Reapply as necessary but not more than twice per week. Applications must be at least 3 days apart. Per the product label, this can be applied into cracks, crevices, or void spaces where listed insects may be harboring, living, and breeding. Place injector tip into cracks, crevices, holes, and other small openings. Release approximately 1 second of product. For light infestations, move injector tip along cracks while treating at the rate of 3 feet per second. For heavy infestations, move injector tip along at 1-foot per second. For closed voids, calculate the void’s cubic area and treat at the rate of 1 to 5 seconds per 3 cubic feet. Several holes may be required in long-running voids.  PT Fendona Pressurized Insecticide used alone will not eradicate a German Roach infestation and repeat applications of spraying the insecticide and reapplying roach bait every 7-14 days is required. If you are not currently using a roach bait and insect growth regulator to help stop the reproduction, we would highly recommend adding these to your treatment program.
