Allergens can trigger the various dust mite symptoms around your home commonly by attaching themselves through the air to clothes and furniture. Every time someone becomes exposed to these garments and furniture around the home, they can initiate an allergic reaction. If you have pets they can attach to allergens from the carpet or outdoors and transfer them to the furniture making it easier to become more vulnerable. The best way to prevent this is to take off clothes before entering the bedroom - changing inside the bedroom will transfer the outside allergens attached to your clothes into the area where you sleep. Various products such as vacuums, steam cleaners, pet detergents and anti allergy sprays, are available to combat dust mite around the house.
