A practical cockroach treatment guide starts with removing food and water sources, sealing cracks, fixing leaks and keeping bins covered. Use cockroach baits or traps according to the product label, and avoid spraying insecticide where it could contaminate food, benches or pet areas. If you see cockroaches during the day, find a large infestation, or the problem keeps returning, a licensed pest controller can identify entry points and recommend suitable treatment. Always follow safety directions, particularly around children, pets and people with asthma.
