What should you know about Demodex mites inside the nose?

Demodex are microscopic organisms linked with follicles and sebaceous glands, especially on facial skin. The deeper inner lining of the nose is not the same as hair-bearing facial skin. Dryness, allergies, a viral illness, irritation from sprays, crusting or a small inflamed follicle can all cause itching, tickling or a crawling sensation.

Redness around the nose may occur with facial conditions such as [Rosacea](/conditions/rosacea/), but that does not mean an internal nasal sensation is caused by rosacea or mites. A clinician can inspect the nostril entrance and surrounding skin, and refer onward if the concern is deeper or persistent.

Avoid inserting cotton buds, tweezers, fingers, essential oils, insecticides or skin creams deep into the nostrils. Use a humidifier or saline product designed for nasal use if dryness is the likely issue, following the product directions. Wash hands before touching the nose and avoid picking crusts.

Arrange a medical assessment if the sensation persists, recurs or comes with visible sores. Do not place [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) inside the nose; scalp products can damage nasal tissue. Treatment should match the confirmed cause and location.

Seek prompt care for repeated nosebleeds, increasing pain, foul-smelling discharge, a one-sided blockage, spreading redness or swelling around the nose. Get urgent help for trouble breathing, rapidly increasing facial swelling, severe headache or feeling acutely unwell. These signs can point to infection, injury or another problem needing examination.

Ask whether the symptoms involve the nasal entrance or deeper lining, whether dryness or infection is more likely, which saline products are suitable, and whether an ear, nose and throat review is needed. Mention sprays, picking, recent illness and any facial rash.
