Things You'll Need
Dust mites are microscopic insects that live and feed on dead skin cells shed from humans and animals. They are generally harmless to people but their fecal matter can cause allergic reactions. Dust mites live in colonies and primarily live in bed mattresses and pillows. They thrive in moist and humid conditions and are eliminated through dehydration or smothering. Borax is a refined compound that is used for cleaning, laundering, or as a pesticide. The refined crystals found in borax will cut the hard exoskeletons of dust mites, causing them to dehydrate. The powder will also suffocate dust mites.
Remove all sheets, blankets, pillow cases, and bed skirts from your bed. Throw your pillows out and replace them with new ones.
Wash all the bedding and sheets in the washing machine in hot water with the correct amount of laundry detergent and 1/2 cup of borax. Stop the machine when it is filled with hot water and let it soak 15 to 20 minutes. Finish the cycle after soaking.
Remove any pets or children from the room and sprinkle a thin layer of borax onto your mattress, carpet or rug. Leave the layer for a few hours. The borax will penetrate the hard exoskeleton of the dust mites and dry them out or smother them. Vacuum your mattress and carpet thoroughly. Make sure to vacuum the seams of your mattress.
Clean and wash hard tile floors and furniture before you bring your linens and bedding back into the room.
Keep borax away from children and pets. It is for external use only and cannot be consumed.
