Does cold air get rid of dust mites?

Dust mites are tiny creatures that are found everywhere in your home. These microscopic pests can cause a range of health problems including allergies and asthma. While there are many ways to reduce the number of dust mites in your home, one of the simplest methods is to expose your bedding and furniture to cold air.

Many people have heard that cold air can help eliminate dust mites, but is this really true? In this blog post, we’ll take a closer look at the relationship between cold air and dust mites.

What are Dust Mites?

Dust mites are tiny arthropods that are found in every home around the world. They feed primarily on dead skin cells shed by humans and pets. They thrive in warm, humid environments and are most commonly found in bedding, carpets, upholstered furniture, and curtains.

Despite their small size, dust mites can cause a range of health problems including allergies, asthma, eczema, and even respiratory infections. For this reason, it’s important to take steps to reduce their numbers in your home.

How Cold Air Affects Dust Mites

Dust mites can’t survive in extreme temperatures, and exposing your bedding and furniture to cold air can help kill them. However, it’s important to note that cold temperatures alone aren’t enough to completely eliminate dust mites from your home.

To kill dust mites, you need to expose them to temperatures below 20°F (-6.7°C) for at least 24 hours. This temperature is cold enough to freeze and kill both the mites and their eggs. However, it’s important to note that most home freezers are not cold enough to achieve this temperature.

Additionally, it’s important to note that just because you’ve eliminated dust mites from your bedding doesn’t mean they won’t return. Dust mites are constantly reproducing and can quickly repopulate areas that have been treated.

Other Ways to Reduce Dust Mites

While exposing your bedding and furniture to cold air can help reduce the number of dust mites in your home, it’s only one part of a larger plan to eliminate these pests. Here are some other methods you can use to reduce dust mites in your home:

Use Dust Mite Covers: These covers are designed to encase your pillows and mattress, preventing dust mites from accessing the areas where you sleep.

Vacuum Regularly: Regular vacuuming can help remove dust and dust mite droppings from your carpets and furniture.

Wash Bedding Weekly: Washing your bedding in hot water (130°F or higher) can help kill dust mites and remove their droppings.

Use a Dehumidifier: Dust mites thrive in humid environments, so using a dehumidifier can help reduce the moisture in your home and make it less hospitable to these pests.


While cold air can help kill dust mites, it’s important to remember that it’s just one part of a larger plan to eliminate these pests from your home. By using a combination of methods like dust mite covers, regular vacuuming, and washing your bedding in hot water, you can significantly reduce the number of dust mites in your home and improve your overall health.


What temperature kills house dust mites?

Dust mites are microscopic creatures that can cause allergic reactions and respiratory problems in humans. They love warm and humid environments, and can be commonly found on bedding, carpets, and upholstered furniture. Fortunately, there are ways to control their population at home, and one effective method is through washing with hot water.

The ideal temperature to kill dust mites is at least 130 degrees Fahrenheit or 54.4 degrees Celsius. This is because at this temperature, the mites’ protein compounds denature and break down, killing them in the process. Additionally, the high temperature can help remove allergens and other unwanted particles that can trigger allergic reactions.

To kill dust mites on bedding and other washable items, it is recommended to use hot water between 130 to 140 Fahrenheit or 54.4 to 60 Celsius. It is also important to make sure that the washing machine is set on a high cycle to ensure effective cleaning. Using a hypoallergenic detergent can also help remove dust mites and allergens, as well as protect sensitive skin from irritation.

For items that cannot be washed directly with hot water, such as stuffed toys or pillows, it is recommended to place them in a dryer set to a temperature above 130 F for at least 15 minutes. This will help kill the mites and remove allergens, leaving them fresh and clean.

Hot water that is at least 130 F or 54.4 C is an effective way to kill dust mites and remove allergens from bedding and other washable items. By following the recommended temperature and washing cycle, individuals can significantly reduce the risk of allergic reactions and respiratory problems caused by these microscopic pests.

Do dust mites hate the cold?

Dust mites are tiny arthropods that live mainly on the dead skin cells of humans and animals. These tiny creatures can cause allergic reactions and asthma symptoms in sensitive individuals. Because of this, many people are interested in controlling their exposure to dust mites. One common question that people have is whether dust mites hate the cold.

The answer is yes, dust mites do hate the cold. These creatures thrive in warm, humid environments where they can feed and reproduce. In fact, they require a relative humidity of at least 50% to survive. When the environment becomes too dry or too cold, dust mites have a hard time surviving.

Moisture is vitally important for house dust mites and they cannot survive in cold or hot-dry climates. When the temperature drops below 70°F (21°C) and the humidity level drops below 50%, dust mites struggle to survive. In fact, when the temperature drops below 60°F (15.5°C), dust mites begin to die off.

Therefore, if you are trying to control your exposure to dust mites, it is a good idea to keep your home cool and dry. You can do this by using air conditioning during the summer months and turning down the heat during the winter months. You can also use a dehumidifier to control the humidity levels in your home.

In addition to controlling the temperature and humidity levels in your home, there are other steps you can take to reduce your exposure to dust mites. These include:

1. Washing your bedding in hot water every week

2. Using dust-proof covers on your pillows and mattresses

3. Vacuuming your home regularly with a HEPA filter vacuum

4. Removing carpeting and soft furnishings from your home

5. Dusting your home with a damp cloth to trap dust mites and their droppings

Dust mites do hate the cold. Maintaining a cool and dry environment is one way to control dust mites in your home. By following other tips to reduce your exposure to dust mites, you can help keep these tiny creatures at bay and reduce your allergy and asthma symptoms.

What kills mites instantly?

Mites can be a frustrating problem to deal with, particularly when they infest the interior of your home. If you are faced with a mite infestation, it’s natural to seek out effective and efficient methods to eliminate them quickly. So, what can you do to kill mites instantly?

One option is to use sprays or aerosols containing synergized pyrethrins. Pyrethrin is a natural pesticide that acts as a neurotoxin to the insect. It causes paralysis and death to mites upon contact, making it an effective way to kill them instantly. The addition of synergizers, such as piperonyl butoxide, increases the potency of the pyrethrins, enhancing their effectiveness. However, these sprays and aerosols only provide a temporary solution as the treatment lasts for a few hours.

Insecticide sprays containing permethrin or bifenthrin are also effective against many types of mites. These synthetic pesticides work by disrupting the mites’ nervous systems, leading to convulsions and eventual death. Unlike pyrethrins, these treatments are long-lasting, providing protection against mites for several weeks.

Another option to instantly kill mites is by using high temperatures. Mites cannot survive extreme heat, so washing your linens and clothing in hot water or using a heat treatment tool such as a steamer can eliminate mites instantly.

There are multiple ways to kill mites instantly. When dealing with mite infestations, it’s important to begin by identifying the type of mite you are dealing with as some may require specialized treatments. While immediate pest control is necessary to eliminate the influx of mites, it’s also important to take measures to prevent future infestations by reducing humidity, vacuuming regularly, and keeping clothes and linens clean.

What keeps dust mites away?

Dust mites are microscopic creatures that feed on dead skin cells and thrive in warm, humid environments. They can cause allergies, asthma, and other health issues in individuals who are sensitive to their droppings. Therefore, it is important to take necessary precautions to keep your home free of dust mites.

One of the most effective ways to keep dust mites away is to reduce the places where they can live. They tend to thrive in soft surfaces like carpets, upholstery, bedding, and stuffed animals. Therefore, it is essential to reduce clutter, remove unnecessary items, and regularly deep clean surfaces and fabrics to eliminate dust and debris that can house the mites.
