Dust mites are tiny organisms that can only be seen under a microscope.  They have eight legs. And are from the families  of spiders. They measure about just one-quarter to one-third of a millimetre.


Thier life cycles consists of several stages. And depending on the particular species,  it usually takes two to five  weeks for an adult mite to mature from its egg.


The female dust mite can produce up to hundred eggs in its life time. And they live for about two to four months.





Dust mites live and thrive at many places in your home. They can be found in your carpets, stuffed toys, mattresses and upholstered furniture.

Though studies have shown that they  love  your bedroom the most. Especially your mattresses.

Dust mites are attracted to dead skin cells shed by humans. A normal person sheds about 1.5 grams of dead skin daily. A quantity enough to feed about one million dust mites.

They thrive most in relatively humidity of about 70-80 percent. A temperature of 70 F is ideal for thier growth.



Dust mites produce a lot og waste around your home. The protein in the  waste products and body parts  of these little spiders are allergens; they trigger allergic reaction.

Even common dust in your home can carry the waste products of these mites. And if you are sensitive to mites , any time you come into contact with such dust , you will experience allergy symptoms.

Dust mites die under low humidity or extreme temperatures, but thier waste products (allergens) will be left behind.

So even in death, the dust mite is still troublesome!



There are so many symptoms of dust mite allergies. Some of them are similar to those of pollen allergy.

Allergens from dust mites can cause an inflammation of your nasal passages. And when this happenes, the following symptoms occur;

– postnasal drip

It’s usually used to control inflammation and symptoms of hay fever. Flonase, Nasonex, Nasacort Allergy 24HR and Omnaris are some of the most common ones of corticosteroids.


– Decongestants

Decongestants are used to reduce the swollen tissues in the nasal passages. And There by easing breathing.

Prevention is always the best policy. There are so many ways you can employ to seriously  limit your exposure to dust mites and thereby preventing the possibility of dust mites allergy.

Some people think that having a clean house is the solution to dust mites allergy.  No. It’s not. No matter how clean your house is , house mites can always find thier way in.

Below are some of the most effective preventive measures you can take against dust mites in your home;


1. Use hypoallergenic mattress and pillow covers;

As we stated earlier , dust mites love your mattress. So get a mattress cover with pores that are too small for them to get into your mattress.  There are so many of such mattress protectors these days. Some of them are made of polyester.  One of the best materials for making hypoallergenic products

Avoid any bedcovers that capture and trap allergens easily.



2.  Wash your bedding every week

You can kill dust mites by using a hot water of about 130F to wash your bedding.

You should wash all your pillowcases,  blankets , sheets and bedcovers at least once every week in order to achieve maximum effects.

In case your bedding can’t be washed , you can put your bedding in a dryer at a temperature above 130F for at least 15 minutes to kill the mites and remove allergens.


3. Maintain low humidity in your home

Dust mites can’t survive low humidity. Keep a relative humidity below 50 percent in your home to inhibit thier growth. You can consider either an air conditioner or a dehumidifier to keep your home humidity low. You can also purchase a hygrometer for measuring the humidity at your home.


4. Remove all dust mites habitats in your home.

Carpets are  some of main habitats of dust mites. Remove wall to wall carpeting in your bedroom. You can replace them with tile, wood, linoleum or flooring.

Also nonwashable curtains should be removed from your bedroom.  Use roll type shades on your windows instead.

Upholstered furniture, blinds and down filled covers and pillows should also be removed from your bedroom.


5.  Vacuum clean often

Vacuuming cleaning regularly might help reduce dust in your home. It’s recommended to use vacuum cleaners with HEPA filters. HEPA filters capture and trap allergens very easily.

But remember that vacuum cleaning May not be enough to remove large amount of dust mites. As they live deep inside mattress, pillows and carpeting.

You can have someone clean your bedroom for you if your allergies are severe. Or you may wear a filtering mask while cleaning.


In conclusion

Dust mites are really notorious organisms. You can’t afford to ignore them. Thier health burden is significant.
