Mosquitoes are commonly repelled by citronella , eucalyptus , lavender , peppermint , and rosemary scents. Citronella and lemon eucalyptus tend to be the best-known options, but results vary by environment and how the scent is used.

Good scents to try

  • Citronella.
  • Lemon eucalyptus.
  • Lavender.
  • Peppermint.
  • Rosemary.
  • Garlic, though the smell is stronger and less pleasant for many people.

What works best

Scent alone usually helps more as a deterrent than a full solution, so candles, sprays, diffusers, or plantings work better when paired with screens, fans, and removing standing water. Lemon eucalyptus is often highlighted because it contains mosquito-repelling compounds used in commercial repellents.

Practical pick

If you want one simple choice, start with citronella or lemon eucalyptus for outdoor use, then add lavender or peppermint for a lighter scent at home.
