How to protect against mosquito bites

Travelling to areas with malaria, dengue, chikungunya or Zika.

• Wear long sleeves and trousers, especially at dawn and dusk.
• Treat clothing and gear with permethrin — it lasts several washes.
• Light colours help; mosquitoes are drawn to dark fabrics.

• Sleep under a permethrin-treated net if the room isn't screened or air-conditioned.
• Use a box or wedge shape so the net doesn't touch your skin.

• Apply repellent after sunscreen, not before.
• Reapply after swimming or heavy sweating.
• Use every evening — and during the day in dengue/Zika areas (Aedes bite by day).
• DEET ≤30% is safe in pregnancy and from 2 months of age.
