How to Kill Dust Mites and Get Rid of Bites on the Skin

Updated February 21, 2017

Biting dust mites are a difficult pest to deal with because you cannot see them. These tiny little creatures can inflict a level of discomfort that is disproportionate to their size. With a little vigilance and by taking some preventive measures around the home, you can get rid of mites in your home---but they will not go away easily. Your entire house will need to be cleaned in order to ensure these biting insects will not return any time soon.

Wash all clothes, bed sheets, pillow cases and curtains in hot water. Dust mites cannot live in temperatures above 60 degrees Celsius. A hot-water wash in a washing machine will exceed this temperature and kill all the dust mites living on your clothes and linens.

Place any items that cannot be cleaned in a washing machine directly in the sunlight during the hottest part of the day. The direct sunlight and the absorption of heat will be enough to kill most dust mites. This method is especially useful for floor and door mats.

Vacuum the entire carpet and use the hose extension to vacuum to reach any dust in the house. As their name suggests, dust mites enjoy living in dust. Removing all dust in the house will dramatically reduce the number of dust mites in the home since you are removing their habitat and a food source.

Fill a bathtub with slightly warm water. Don't use hot water; a hot bath can exasperate a dust mite bite and make it much worse.

Place colloidal oatmeal in the bathtub until the bath appears to have a milky consistency. Colloidal oatmeal is oatmeal that has been crushed into fine pieces and used almost exclusively for skin irritations.

Sit in the bath until the itchiness subsides. Scratching a dust mite bite will only worsen the symptoms of the bite. The soothing affects of the colloidal oatmeal bath will speed the recovery process.

Step out of the bath when done and place anti-itch cream on all the dust mite bites. This will alleviate the symptoms associated with the bite, including swelling, and speed your healing.


Start the dust mite extermination process before you start trying to rid your body of bites. As long as the dust mites are in your home, they will continue to bite you. Killing the dust mites is the best way to prevent new bites on your body.
