what oil repels mosquitoes

Several plant-based oils are known to help repel mosquitoes, although they’re generally less long-lasting than strong synthetic repellents and should always be used with care on skin, especially for children and pregnant people.

Quick Scoop: Oils That Repel Mosquitoes

The best-known mosquito‑repelling oils include:

  • Lemon eucalyptus oil – One of the most researched natural repellents; a preparation with around 30% lemon eucalyptus oil gave over 95% protection for about 3 hours in one study.
  • Citronella oil – Classic candle and spray ingredient; helps mask human scent and can reduce mosquito landings for a short period.
  • Lavender oil – Pleasant scent with reported repellent effects; one study found it could reach about 80% effectiveness for several hours.
  • Peppermint oil – Strong minty smell that can deter mosquitoes and can also feel cooling on bites.
  • Catnip (catmint) oil – Laboratory tests have shown very strong repellent action, in some cases comparable to or better than DEET over short periods.
  • Cinnamon oil – Spicy oil that has shown significant repellent activity against certain mosquito species.
  • Clove oil – In testing against many essential oils, clove gave one of the longest durations of 100% repellency (up to about 4 hours).
  • Thyme oil – Demonstrated repellent properties in laboratory tests and is often listed among effective natural options.
  • Tea tree oil – Used more often for soothing bites, but it also has insect‑repellent properties.
  • Basil and cedarwood oils – Aromatic oils that can help discourage mosquitoes (and in cedar’s case, other insects like ticks and flies).

How People Commonly Use Them

People typically use these oils in diluted forms, not straight on the skin, because essential oils can irritate or cause allergic reactions.

Common approaches include:

  1. Mixing a few drops of essential oil into a carrier oil (like coconut, jojoba, or soybean oil) and applying to exposed skin, avoiding eyes, mouth, and broken skin.
  2. Adding oils to a spray base (water plus a small amount of alcohol or witch hazel) and shaking before each use.
  3. Using them in diffusers, candles, or on outdoor fabrics to create a scented “barrier” in a small area.

Because natural repellents often wear off quickly, many people reapply every 1–3 hours when mosquitoes are active.

Limits and Safety (Important)

  • Natural does not automatically mean safe: some essential oils can trigger asthma, skin burns, or serious irritation if too concentrated. Patch‑test first and keep away from kids’ hands and faces.
  • If you are in an area with mosquito‑borne diseases (like malaria, dengue, or Zika), public‑health agencies still recommend proven repellents (such as DEET, picaridin, or oil of lemon eucalyptus products specifically approved as repellents), long sleeves, and bed nets; do not rely on homemade oil blends alone.

Mini takeaway

If you’re wondering “what oil repels mosquitoes” for casual backyard use, lemon eucalyptus, citronella, lavender, peppermint, catnip, and clove are among the most frequently recommended options, used in well‑diluted, frequently reapplied mixtures.
