Is boric acid an effective solution for severe cockroach infestations in residential settings?
Boric acid is a proven, low-cost insecticide for cockroach control, acting as a stomach poison that causes dehydration. When mixed with attractive baits like sugar water or food scraps, it exploits cockroaches' foraging behavior, driving them to seek water after ingestion, often leading them to exit treated areas. This mechanism makes it particularly effective in dormitories and kitchens where chemical sprays pose health risks. However, efficacy depends on correct formulation and placement—powder must remain dry to adhere to insect bodies, and bait stations should be replenished regularly. While boric acid is less toxic to humans than many synthetic pesticides, it is not harmless; ingestion of large quantities can cause acute poisoning, as documented in rare case reports. For severe infestations, integrated pest management combining boric acid with sanitation and exclusion measures yields the best results.
