There are several ways you can reduce bird dust in your home. Vacuuming regularly and using an air purifier with a HEPA filter will help to capture airborne particles, such as bird dander, that may be causing allergens in your home. Additionally, keeping the cage clean and changing its litter often can help reduce the amount of dust particles that are released. Finally, try to limit the amount of household dust by regularly wiping down surfaces and using a damp cloth to remove any buildup of dust or debris.
