Description: Dust mites are second only to pollen in causing allergic reactions. Asthma, eczema and allergic rhinitis are the three main allergic diseases where the cause of most attacks has been linked to them. It is not only the dust mite that causes the problem. The allergen which causes these allergic reactions is actually a protein found in their droppings and carcasses. On this page we show you how to get rid of dust mites without using toxic dusts and sprays.
Note: Recent studies suggest that at least 45 percent of young people with asthma are allergic to house mites. Unlike “seasonal” allergies caused by molds and pollen, people who are allergic to dust mites often will have symptoms year round.
House dust mites are microscopic, eight legged creatures, 0.3 mm in length, and invisible to the human eye. They are arachnids, relatives of spiders, not insects. The mites are globular in shape, clear to creamy white in color, with hairs on their legs and body.
Life Cycle: Adult females lay 40 to 80 cream-colored elliptical eggs. After eggs hatch, they pass through six developmental stages, and the adult form may also molt once. The life cycle from egg to adult is about one month with the adult living an additional one to three months.
A primary source of exposure in the home is in the bedroom, which provides the best conditions of warmth, humidity, and food for their growth. Mites survive by eating dead skin cells, which make up to 80% of house dust. They also live off water vapor, which we provide for them through perspiring and breathing, approximately one pint per person per night.
Dust Mite Control: Getting rid of dust mites entirely is not a realistic goal. As a result, pest management should focus on reducing human exposure to allergens as well as making the household environment inhospitable to the pest. Sleeping areas deserve the most attention. The following steps should be taken:
1) Select appropriate furnishings. Avoid furniture that collects dust — overstuffed furniture, fuzzy textiles.
2) Enclose mattresses in plastic covers and replace feather pillows and down quilts with synthetic fibers.
3) Wash bedding — pillow cases, sheets, blankets and mattress pads — every two week in hot water.
4) Avoid using curtains, drapes or blinds on windows. Use plastic shades instead.
5) Eliminate or reduce fabric wall hangings such as tapestries or pennants.
6) Wall to wall carpet should be avoided — replace with smooth hard surfaces that are easy to clean.
7) Pets with fur or feathers contribute to dander and increase the food source for mites.
8) Vacuum mattresses and the seams and framework of beds on a regular basis.
9) Reduce household humidity levels to below 70%.
10) Treat with least-toxic solutions when necessary.
