Controlling Dust Mites: What You Need to Know

What Are Dust Mites?

Dust mites are microscopic, insect-like creatures that feed on dead human skin cells. They’re invisible to the naked eye, but thrive in warm, humid environments, especially in bedding, mattresses, and upholstered furniture.

Do You Have Dust Mites?

Chances are, yes! Millions of dust mites live in most homes, feeding on shed skin cells from humans and pets. While they’re impossible to eliminate completely, understanding their habits can help you manage their presence.

Are Dust Mites Harmful?

  • Directly? No. Dust mites don’t bite, live in hair, or spread disease.
  • Indirectly? Yes. They produce allergens that can trigger respiratory issues, allergies, and skin irritation, especially in sensitive individuals.

When Are Dust Mites a Problem?

  • Peak Season: Depending on where you live, when moisture levels are high.
  • Winter Woes: Though most mites die off in colder months, their allergens linger in dust, worsening symptoms as heating systems circulate air.
  • Nighttime Activity: Dust mites thrive in beds, where humans shed the most skin cells.

Signs You May Be Allergic to Dust Mites

  • Sneezing, coughing, watery eyes
  • Runny nose, nasal congestion
  • Skin irritation, itching
  • Worsening asthma or difficulty breathing
  • Increased sinus infections due to chronic inflammation

Left unmanaged, dust mite allergens can lead to severe asthma, bacterial infections, and even long-term sleep and mood disturbances.

Did You Know? Food Allergies & Dust Mites

If you’re allergic to dust mites, you might also react to shellfish like lobster, crab, and shrimp due to similar proteins.

How to Reduce Dust Mites in Your Home

  • Control Humidity: Keep indoor humidity below 50% using a dehumidifier. Dust mites thrive at 75-80% humidity.
  • Let in Fresh Air: Open windows in warmer months to circulate air and reduce allergens.
  • Shower Before Bed: Wash away dust mites and allergens before settling into bed.
  • Use Hypoallergenic Bedding: Opt for organic cotton, wool, or microfiber bed linens.
  • Protect Your Mattress & Pillow: Use breathable, waterproof protectors to limit dust mite populations.
  • Wash Bedding Weekly: Use hot water (130°F or higher) to kill dust mites.
  • Try Aromatic Sprays: Essential oils like clove, eucalyptus, lavender, peppermint, and rosemary can repel dust mites when lightly misted on mattresses.
  • Vacuum Frequently: Regular vacuuming reduces dust and allergens in carpets, furniture, and curtains.
