The Best Cockroach Powder Killer for Hard-to-Reach Areas

Unlike sprays and gels, this cockroach killing powder gets into cracks, crevices, wall voids, and tight spaces where roaches hide and breed. Apply it behind appliances, under sinks, inside cabinets, and along baseboards. As a powder to kill cockroaches, boric acid works by damaging the roach's exoskeleton and digestive system — killing them from the inside out. It keeps working as long as it stays dry, making it one of the most long-lasting roach killing powders available.
