For German roach and hiding insect control use targeted insecticidal dusts applied precisely to cracks, voids, and electrical outlets where these pests hide.

Delta Dust, a synthetic pyrethroid dust that contains deltamethrin, is widely used because it adheres to insect cuticles and provides long residual control; apply it sparingly with a hand duster into cracks, baseboard voids, behind appliances, inside cabinet joints, and lightly puff into the void behind wall outlets after switching power off and verifying it is safe to work there. Boric acid dust remains a reliable low-toxicity option for many homes when placed dry in thin layers where roaches walk, avoiding bulk piles that repel insects; it works best when baits and sanitation are used concurrently because boric acid requires ingestion following grooming. Silica gel and diatomaceous earth damage the insect wax layer and are effective in dry locations such as crawlspaces, wall voids, and under sinks, but they lose effectiveness if they become wet so reapply after moisture events. Use a fine, precise applicator and a little dust goes a long way because thick deposits can be avoided by pests and will be tracked into living areas. Rotate active ingredients when possible to reduce selection for reduced susceptibility, and always follow label directions for application rates, safety precautions, and reentry times. Wear appropriate respiratory and hand protection, keep children and pets away until surfaces are dry or settled, and document placements so follow up inspections can confirm efficacy.

Common mistakes include overapplication that creates visible piles people and pets can contact, which you avoid by applying only a light, even film and wiping any excess; failing to treat electrical outlets and voids where roaches shelter, which you prevent by deenergizing circuits when possible and applying dust carefully with an outlet-safe technique; and relying on dusts alone without sanitation or baiting, which you correct by combining dust placement with removal of food and water sources and strategic use of gel baits to reduce populations quickly.
