The real health risks of a roach infestation
Yes. Cockroaches are a recognized health hazard. They can contaminate food and surfaces, spread bacteria, and trigger allergies and asthma — with children often affected the most.
Roaches crawl through drains, garbage, and dirty spaces and then across counters, dishes, and food, which can spread germs onto anything they touch. Their droppings, shed skins, and body parts also release allergens into household dust and the air. For people with asthma or allergies, and for young children, that can mean more frequent symptoms even without seeing the roaches directly.
Because of these real risks, a serious infestation is treated as more than a nuisance under California's habitability standard — it is a health and safety problem the landlord is expected to address. This is general information rather than medical advice, so a doctor should evaluate any symptoms. If an infestation is affecting your household's health, a free review can explain how that fits into your rights.
