Remove carpeting and other dust mite habitats.
If possible, replace wall-to-wall bedroom carpeting with tile, wood, linoleum or vinyl flooring. Consider replacing other dust-collecting furnishings in bedrooms, such as upholstered furniture, nonwashable curtains and horizontal blinds.
Use a HEPA air purifier for dust removal. You need a high quality HEPA filter with sufficient air flow to effectively clean your room so you are not breathing in the dust mites and whatnot. Cover your pillows and mattress in an allergen cover.
Anti-Dust Mite Spray
Use a disinfecting spray after dusting and wiping surfaces such as floors, shelves, blinds, skirting boards, and corners, since it not only kills the dust mites but also creates an inhospitable environment for them. You can also use an anti-allergen spray.
Spray Lysol on dust surfaces to kill dust mites
After cleaning dust surfaces with a vacuum, apply and spray Lysol on your furniture and fabrics.
Essential oils contain compounds that repel or kill insects, including dust mites. The best essential oils for getting rid of dust mites are clove, rosemary, and eucalyptus oil. Add 20 drops of oil to four ounces of witch hazel, and spray your mattress, couch, drapes, and other dust mite hangouts.
Kill dust mites immediately with tea tree oil
Spray this solution around your home on your upholstery, bedding, carpets, and rugs at least once per week to keep dust mites at bay and make you home smell fresh.
Start by adding a cup of vinegar (just the plain white vinegar) and a cup of water to the spray bottle. Then add about 15 drops of tea tree oil and about 5 drops of peppermint oil to the bottle. Put the spray top on and give it a good shake.
Predators. The predators of dust mites are other allergenic mites (Cheyletiella), silverfish and pseudoscorpions.
Because dust mite particles often become airborne, using an air purifier with a high-efficiency particle air (HEPA) filter can also help remove these and other allergens from the air. If you suffer from allergies and asthma, dust mites can be a major indoor trigger that make your symptoms worse.
If you have a central air conditioner, make sure you use it consistently throughout the summer. Air conditioners don't just cool your home; they also remove moisture from the air, helping to keep dust mites at bay.
Dust mites occur naturally and can appear in nearly all homes. Humidity is the most important factor in determining whether a house has high levels of dust mites. This is because dust mites do not drink water like we do; they absorb moisture from the air.
Three most important functions to human life are heartbeat, breath and sleep. An active allergy to house dust mites (HDM) can interfere with breath and sleep. Wheezing, sneezing or itching, caused by an allergic reaction, is a known risk to sleep.
If you haven't cleaned out the vacuum bag in a while, there is a good chance it's full of microscopic dust mites. Many people are not aware, but mold is alive.
In contrast, dust mites can really only be seen under the microscope. House dust mites are about 0.1–0.4 mm long [2], less than one tenth the size of a bed bug, at least. House dust mites are translucent to white in color and have been described as “globular” in shape [3].
Only use hypoallergenic bedding
Materials like organic cotton, wool, bamboo, and microfiber are made of moisture-wicking, antimicrobial materials that are naturally resistant to dust mites and mildew. Down alternative comforters are also less likely to trigger allergies.
Tea Tree Essential Oil is a natural antiseptic, antibacterial, and deodorizer. Eucalyptus oil, in specific concentrations, has been scientifically proven to kill 99.99% of dust mites. If you are into natural cleaning options and remedies, this is definitely a good place to begin at killing off dust mites.
Dust mites live and multiply easily in warm, humid places. They prefer temperatures at or above 70 degrees Fahrenheit with humidity of 75 to 80 percent. They die when the humidity falls below 50 percent.
Allergies often get worse at night as laying down increases congestion and common allergies like dust mites thrive in your bedroom. To reduce symptoms, try showering before bed, washing your bedding regularly, and sleeping with your head elevated.
Any extreme in temperature kills dust mites, though. That means anything really hot or really cold. Most experts agree that exposing dust mites to temperatures over 130 degrees (such as in hot water washing) will kill dust mites. Freezing temperatures will kill dust mites, too.
