Dandruff allergens are notoriously sticky and can remain on surfaces for extended periods of time. Unless special measures are taken, pet dander can linger in a home for up to six months after the pet has been removed. Cat dander is a particularly potent allergen that can cause allergies in sensitive people, so it is essential to understand how long it stays on surfaces in order to reduce exposure. Cat dander is lightweight and easily carried through the air, which means it can remain for months if not removed properly.
Fabrics and upholstery are often magnets for cat dander due to their static properties, and pet allergens can build up on furniture and other surfaces. Allergens can adhere to walls, fabric furniture, and clothing, and they may stay at high levels for several months. Pet allergens can even cause symptoms up to six months after the animal dies, especially cat allergens. Pet dander and other pet allergens can stay in the air longer than other allergens because they are microscopic and irregularly shaped. This means they can fly easily and attach to furniture, bedding, fabrics and even transport them in and out of the house.
Pet dander usually persists in the house for 4 to 6 months, even if the place is pet-free. To eliminate accumulated dandruff and thoroughly clean air ducts to eliminate allergens, a professional air duct cleaning service should be used. You can also create a pet-free zone and use air filters to reduce the amount of allergens in the air.
