About This Product
Harris Boric Acid Roach & Silverfish Killer is an EPA-registered powder that uses boric acid with a food-grade lure to attract and kill roaches, silverfish, and waterbugs. The powder is applied in thin layers in cracks, crevices, and behind appliances where roaches hide. It provides long-lasting residual control and is safe for use in kitchens and food-handling areas when applied as directed. With 15,000+ Amazon reviews, it is one of the most trusted DIY roach control products available.
Why Pest Control Bros Recommends This
Harris Boric Acid stands out because of its 99% boric acid concentration paired with a proprietary food-grade lure — most competing powders skip the attractant entirely. The EPA registration gives us confidence in both its safety and efficacy claims. With over 15,000 Amazon reviews and decades of use by pest control professionals, this is the benchmark boric acid product for DIY roach control.
Using This Product in Arizona
Arizona's German and American cockroach populations thrive in the warm, dry conditions found behind refrigerators, under stoves, and inside wall voids. Boric acid powder excels in these dry Arizona environments because it stays effective indefinitely as long as it remains dry — unlike liquid sprays that degrade faster in extreme heat. Apply thin layers in kitchen cabinet hinges, under appliances, and along the garage perimeter before monsoon season when roach activity spikes.
