What To Spray On Mattress For Dust Mites?

If you’re looking to tackle the persistent issue of dust mites in your mattress, several solutions and sprays are designed specifically for this purpose. Sprays containing essential oils like eucalyptus, tea tree, or peppermint, as well as commercial dust mite sprays, can effectively reduce dust mite populations and alleviate allergy symptoms.

What Are Dust Mites?

Dust mites are microscopic creatures that thrive in warm, humid environments, feeding on dead skin cells shed by humans and pets. These tiny pests are common in household items such as mattresses, pillows, bedding, and upholstered furniture. Although they do not bite, their presence can trigger allergic reactions such as sneezing, runny nose, itchy eyes, and even asthma attacks. Understanding what dust mites are and the environment they thrive in is the first step in effectively dealing with them.

Why You Should Be Concerned

Dust mites produce waste particles that become airborne and can be easily inhaled. For individuals who suffer from allergies or asthma, exposure to these particles can significantly impact health and quality of life. Symptoms like nasal congestion, itchy eyes, and respiratory issues can worsen if the dust mite population is not controlled. Moreover, long-term, unmanaged exposure to dust mites can exacerbate chronic respiratory conditions and lead to persistent discomfort.

Essential Oils for Dust Mite Control

Essential oils are a popular natural remedy for dust mites. Many essential oils have properties that are effective at repelling or killing these tiny parasites. Below are some of the most effective options:

Eucalyptus Oil

Eucalyptus oil is well-known for its potent antiseptic properties. It contains compounds that are toxic to dust mites, making it a popular choice for those looking to reduce dust mite populations naturally. To use eucalyptus oil, you can create a spray by mixing 20 drops of the essential oil with a cup of water in a spray bottle. Shake well and lightly mist the surface of your mattress, allowing it to air dry.

Tea Tree Oil

Tea tree oil is another essential oil that possesses anti-microbial and anti-inflammatory properties, making it effective against dust mites. A solution of water and tea tree oil can be sprayed on your mattress every few weeks to keep dust mites at bay. For best results, combine 10 to 15 drops of tea tree oil with a cup of water in a spray bottle.

Peppermint Oil

Peppermint oil has a strong scent that dust mites find repellent. Not only does it help in reducing dust mites, but it also leaves a refreshing smell on your mattress. You can create a mixture with 10 drops of peppermint oil and one cup of water. Spray this solution lightly over your mattress and other areas where dust mites are likely to reside.

Commercial Dust Mite Sprays

For those who prefer pre-made solutions, a variety of commercial dust mite sprays are available. These sprays often contain active ingredients that specifically target dust mites and are tested for efficacy. Some common types include:

Benzyl Benzoate-Based Sprays

One of the most effective ingredients found in commercial dust mite sprays is benzyl benzoate. This chemical works by affecting the nervous system of dust mites, effectively killing them. Many products containing benzyl benzoate also include other active ingredients like natural essential oils, making them a potent choice for those looking to eradicate dust mites from their mattress.

Tannin Acid-Based Sprays

Another effective type of commercial dust mite spray is tannin acid-based. Tannin acid works by denaturing the proteins in dust mite allergens, making them less likely to cause allergic reactions. This type of spray can be particularly beneficial for individuals who suffer from severe dust mite allergies.

Maintaining a Dust Mite-Free Mattress

Using sprays is just one part of a comprehensive approach to maintaining a dust mite-free environment. Here are some additional strategies to consider:

Regular Washing: Washing your bedding, including sheets, pillowcases, and mattress protectors, in hot water at least once a week can significantly reduce dust mite populations. Hot water effectively kills dust mites and removes their waste products.

Humidity Control: Dust mites thrive in humid environments. Using a dehumidifier or air conditioner to maintain humidity levels below 50% can make your home less hospitable to these pests.

Encasing Mattresses and Pillows: Specially designed dust mite-proof covers can prevent dust mites from penetrating your mattress and pillows. These covers are usually made from tightly woven fabrics that dust mites cannot infiltrate.

Vacuum Regularly: Regular vacuuming with a vacuum cleaner equipped with a HEPA filter can help remove dust mites from carpets, upholstery, and mattresses. Be sure to vacuum all surfaces, including the mattress itself, at least once a week.

DIY Dust Mite Spray Recipes

If you prefer making your own sprays, you can easily create effective solutions at home using simple ingredients. Here are a couple of DIY recipes to get you started:

Essential Oil Spray

Combine 20 drops of eucalyptus oil, 10 drops of tea tree oil, and 10 drops of peppermint oil with a cup of water and a tablespoon of vodka or rubbing alcohol (to help the oils mix with water) in a spray bottle. Shake well before each use and lightly mist the mattress.

Vinegar and Baking Soda Spray

Mix one cup of white vinegar with one cup of water and add a few tablespoons of baking soda. This combination not only helps in killing dust mites but also deodorizes the mattress. Spray the solution lightly on the mattress and let it air dry. Vacuum the mattress afterwards to remove any residue.

How to Apply Dust Mite Sprays Effectively

Knowing how to apply dust mite sprays correctly can significantly enhance their effectiveness. Here are some tips:


Before applying any spray, remove all bedding and wash it in hot water. Vacuum the mattress thoroughly using a vacuum cleaner with a HEPA filter. This pre-treatment helps remove surface dust mites and dirt, allowing the spray to penetrate deeper.


Hold the spray bottle about 6 to 8 inches away from the mattress and apply a light, even mist. Make sure to cover all surfaces, including the sides and edges of the mattress. Allow the mattress to air dry completely before replacing the bedding.


For the best results, use dust mite sprays once every two weeks. This frequency strikes a good balance between effectiveness and convenience, ensuring that dust mite populations are kept under control without requiring excessive effort.

Safety Considerations

While most essential oils and commercial sprays are generally safe for use, it’s important to consider safety, especially if you have allergies or sensitive skin. Always perform a patch test on a small, inconspicuous area of the mattress before fully applying any spray. If using essential oils, ensure that they are properly diluted, as undiluted oils can cause skin irritation or allergic reactions.


Always use sprays in a well-ventilated area to minimize inhaling any fumes or strong scents, particularly if you are sensitive to strong smells. Open windows and doors to ensure proper air circulation while applying the spray and as the mattress dries.

Label and Storage

If you’re making your own spray, clearly label the bottle with its contents and the date it was made. Store all sprays out of the reach of children and pets to avoid accidental ingestion or misuse.

Additional Tips for Reducing Dust Mites

Besides sprays, here are some additional measures that can complement your efforts:

Regular Cleaning

Increase the frequency of cleaning not just your mattress but the entire bedroom to minimize dust accumulation. Dust mites can easily migrate from one surface to another, so keeping all areas clean is crucial.

Avoid Clutter

Clutter, like piles of clothes and toys, can harbor dust mites. Keep your room organized and clutter-free to reduce hiding spots for these pests.

Use Hypoallergenic Products

Switch to hypoallergenic bedding, pillows, and mattresses that are designed to resist dust mites. These products are made from materials that are less attractive to dust mites and easier to clean.

Sunlight Exposure

Dust mites are sensitive to sunlight. Occasionally placing your mattress and pillows in direct sunlight can help reduce dust mite populations. The UV rays in sunlight can kill dust mites and other microorganisms dwelling in your mattress.

Importance of Professional Cleaning

If you find that home remedies and DIY sprays are not enough, consider professional cleaning services. Professional cleaners have specialized equipment that can effectively remove dust mites and deep-clean your mattress. This can be especially beneficial if you suffer from severe allergies or asthma. Having your mattress professionally cleaned once or twice a year can keep it in optimal condition and significantly reduce dust mite populations.
