Summary: Dust mites die after 6 to 11 days at a relative humidity of 50% or less. However, even above 50% relative humidity, the lower the humidity the less the reproduction and allergen production of dust mites.
Dust mites thrive in humid environments ranging between 55% to 75% relative humidity (RH), while RH levels below 50% will create unfavourable conditions that eliminate dust mites. By using a dehumidifier, you'll be able to control RH levels in spaces of your room and effectively stop the growth of dust mites.
Maintaining RH below 50% is one recommendation in a comprehensive plan to reduce house dust mites and mite allergen levels in homes. Even when mean daily RH is reduced below 50%, RH may rise above 50% intermittently for brief periods because of activities in the home (eg, cooking, bathing, and ventilation).
(It can take more than two hours for the dust to settle after a thorough cleaning—so, if possible, clean when the allergic patient is away, and avoid cleaning the bedroom of an allergic person at night.) Use “mite-proof” cases on your mattresses and pillows. Wash all bed linens regularly, using hot water.
Reduce Humidity: Dust mites hate dry air. Utilize dehumidifiers to maintain an environment where they cannot thrive.
Unfortunately, although a dust mite may live for only 2-3 months, dust mite allergen particles continue to cause allergy symptoms even after the mite that produced them has died. Q: What is the difference between dust mites and bed bugs? A: Both dust mites and bed bugs can find an ideal living environment in your bed.
Regular cleaning and vacuuming with a product like Steri-Fab or Bedlam will have the greatest impact. Bedlam Insecticide is a ready to use aerosol that is specially designed to control bed bugs, lice and dust mites.
Reduce the places where dust mites can live.
Remove drapes and curtains. Cover mattresses and pillows with allergen encasements. Wash bedding in hot water (at least 120 degrees F) once a week. Reduce clutter, stuffed animals, and other places where dust mites live.
Combine Clove, Eucalyptus, Lavender, Peppermint or Rosemary oil with water in a spray bottle and spray your bed, linens, and other furniture lightly with a fine mist. Once this mixture air dries, the scent should repel dust mites.
You can't feel dust mites crawling on you. They're too small. The bugs may catch a lift on your clothes but they don't live on humans. Consult your healthcare provider if you have any concerns about crawling sensations or think you may have dust mite allergy.
Dust mites grow best where there is moisture. Moisturizing the air with a humidifier creates the perfect home for dust mites to live and prosper. Keep the humidity level in your house between 40-50%. You can monitor the levels with a hygrometer.
A dehumidifier like the Meaco 20L Low Energy Dehumidifier with it's HEPA filter provides an effective combined approach to dealing with the Dust Mite issue.
House dust mites disappear when you ventilate your bedroom
However, if you keep your window open for 15 minutes, this only produces a short-lasting effect. What you actually need is a room that is ventilated throughout the day. The Healthbox 3.0 by Renson® provides many options for doing this.
Cons of Dehumidifiers
Dehumidifiers collect water meaning they need to be regularly emptied. They also need to be regularly cleaned otherwise black mould can start to grow on the machine , which can induce a wide range of health problems including allergic reactions, lung problems and irritation.
One of the best ways to get rid of dust mites is to wash all your bedding—including sheets, blankets, pillowcases, and duvet covers—on a hot cycle of at least 130 degrees. 2 If you can't wash your bedding in hot water, place it in the dryer for 15 minutes at 130 degrees.
The purpose of dehumidifiers is to take moisture out of the air and thus make it impossible for mold, mildew, or dust mites to survive and thrive.
Essential Oil Sprays: Certain oils like eucalyptus or tea tree oil are natural dust mite repellents. Commercial Anti-Mite Sprays: Choose sprays that are safe for use on mattresses and effective against dust mites.
Dry vacuuming doesn't pick up dust mites. Consider steam cleaning carpets when possible. In addition to cleaning the carpet, the heat of the steam kills dust mites. You can buy chemicals (ascaricides) that kill dust mites and that you can use on carpeting and furniture.

Signs of Dust Mites in a Mattress
Finding dust mite debris such as tiny black or brown specks on the mattress. Feeling itchy skin while you're in bed. Experiencing allergy symptoms while sleeping, such as watery eyes, runny nose, sneezing, a sore throat, coughing, or breathing problems2.
Predators. The predators of dust mites are other allergenic mites (Cheyletiella), silverfish and pseudoscorpions.
Sleep disruption: Dust mite allergies can disrupt sleep patterns, especially if symptoms like sneezing, nasal congestion, and coughing are more pronounced at night. This can spill over into a long-term health risk, as poor sleep quality can have a negative impact on your overall well-being.
House dust mite droppings consist of 3 to 5 food balls bound together by mucus. Each ball is wrapped in a semipermeable membrane. The dropping, containing scraps of undigested food and digestive enzymes, is then excreted. The enzymes help turn leftovers into future food for the mite.
