Mice, Allergies and Asthma in NYC Apartments
In many New York apartments the health problem with mice is not a bite or a famous disease. It is the dust. Mouse urine, droppings and dander can trigger allergies and asthma, especially in children. This guide explains the link, how to spot a problem and what helps. It is general information, not medical advice.
The link between mice and asthma
Research on city housing has found mouse allergens in many homes, and exposure has been linked to asthma symptoms, especially in children. The allergens come from urine, droppings, hair and skin flakes. They settle into dust, carpets, bedding and kitchen cabinets, and they can stay in a home after the mice are gone.
Signs your home may have a mouse allergen problem
Look for droppings, urine smells, gnaw marks and nests, and for symptoms that seem worse at home such as night coughing, wheezing, sneezing or itchy eyes. Kitchens, bedrooms and closets near walls are common hot spots. If you see signs of mice and someone at home has asthma, talk to a doctor and deal with the mice quickly.
How to cut exposure
Stop new mice first by sealing gaps and trapping, because cleaning is wasted if more droppings arrive tomorrow. Then clean with a wet method, wearing gloves and a mask, using a damp cloth and a HEPA vacuum rather than a broom. Wash bedding, store food in hard containers and keep clutter off the floor. Cleaning cabinets and shelves thoroughly matters because allergens collect there.
What your landlord must do
In a NYC rental, the owner is generally responsible for keeping the building free of mice and must use integrated pest management, which means sealing and sanitation as well as treatment. Put the request in writing, keep copies, and report to 311 if nothing happens. Our landlord and tenant guide has the steps.
When to call a professional
Call when you see repeated droppings, hear activity in the walls, or when anyone at home has asthma. A professional finds entry points, traps the mice, seals the gaps and can handle cleanup and disinfecting of contaminated areas. See our costs guide for mouse control prices in 2026.
