Yes, on the surfaces you spray. Eucalyptus oil is backed by published research for killing dust mites, and our plant-based formula kills the mites it reaches on protectors, sofas, carpets and curtains. What no spray can do is reach the millions of mites deep inside your mattress, pillows and duvet. That is why the spray works best with zipped protectors that seal those mites in.

Nothing kills every dust mite in your home instantly. A contact spray like ours kills the mites on the surface as it is applied and dries, washing at 60°C kills them in bedding, and freezing works over several hours. For the mites inside your mattress, pillows and duvet, the fastest fix is to seal them in with zipped protectors so they can't reach you from the first night.

Yes. In a study published in the Journal of Allergy and Clinical Immunology (Tovey and McDonald, 1997), washing blankets in a eucalyptus oil solution reduced live dust mites by up to 99%. Our spray uses Eucalyptus globulus leaf oil as its active ingredient, alongside plant-based soaps that break down the mite's protective outer layer.

Weekly. Dust mite eggs hatch in around 6 to 12 days, so spraying once a week kills each new hatch before it can mature and lay more eggs.

We recommend spraying the outside of a zipped mattress protector rather than the bare mattress. Most dust mites live deep inside the mattress where no spray can reach, so the protector seals them in and the spray keeps the surface clear. Always let it dry fully before making the bed.

Seal it. A zipped mattress protector blocks 100% of dust mites, cutting off the ones inside from you and their food source. Then spray the protector surface weekly, wash your bedding at 60°C, and keep bedroom humidity below 50% with a dehumidifier.

Use it as directed and keep children and pets out of the room while you spray and until the area is fully dry. Keep the bottle out of reach of children, do not spray directly onto people or pets, and do not use it on pet bedding.

Yes, with care. If you have asthma, spray, leave the room, and come back once the area is dry and aired. The formula contains eucalyptus oil, which can cause an allergic reaction in some people, so patch test first if you have sensitive skin. For lasting relief, sealing your bed with protectors does far more than any spray.
