Keep your Kitchen Clean
Cockroach saliva, droppings and decomposing body parts contain allergens that can exacerbate the symptoms of allergy sufferers.
Vacuum
Many people have a dust mite allergy. These pests feed on human and animal dead skin cells, and vacuuming at least once a week using a machine with a HEPA (high-efficiency particulate) filter can help to prevent them.
Wash Clothes Regularly
Dust mites are most frequently found in the bed, where dander is most abundant. Launder linens frequently in hot water, preferably heated to 130 degrees Fahrenheit, and consider encasing pillows and mattresses in allergen-proof covers.
