Mites are microscopical spiders the size of 200u. In particular, Dermatophagoides pteronyssinus and Dermatophagoides farinae (Fig. 1), living in house dust, they are important agents responsible for allergic disorders.
These mites live in house dust and in beddings like mattresses, blanket and pillows, feeding on epithelial dander.
House mite allergy is a hypersensitive reaction to proteins in the excretion of dust mites. The protein attacks the respiratory passages causing hay fever and asthma. It will aggravate dermatitis in people who have a tendency to this problem.
House dust mites (Fig. 2) are found in all homes. They are microscopic organisms that thrive in warm and humid houses with lots of food – human skin. The mites prefer to live in beds and, because we spend about a third of the day in bed, we inhale large quantities of dust mite allergens.
The excretion of the mites (Fig. 3) contains a number of protein substances. When these are inhaled or touch the skin, the body produces antibodies. These antibodies cause the release of a chemical called histamine that leads to swelling and irritation of the upper respiratory passages – typical asthma and hay fever symptoms.
Unlike pollen, dust mites are present all year round causing constant allergy – ‘perennial’ allergic rhinitis. The excretion from the mites dries out and can be launched into the air when someone walks over a rug, sits down in a chair, or shakes the bed clothes, giving allergic people immediate symptoms.

How It Works?
The Dust Mite Controller emits pulsing ultrasonic waves at a frequency of 40,000Hz which is totally harmless for humans and pets, but very annoying for the dust mite. The ultrasonic waves seem to interfere in the growing cycle of house dust mites, reducing the allergenic presence in the domestic environment. For best results, keep plugged in at all times. Benefits are noticed after about 2 months of use, when the population on dust mites dramatically reduces.
