Mosquitoes are more than just a nuisance — in many parts of the world, they can carry serious diseases such as malaria, dengue, Zika virus, chikungunya, yellow fever, and Japanese encephalitis. These illnesses can range from mild discomfort to severe, even life-threatening, complications. Fortunately, with the right precautions, you can significantly reduce your risk while still enjoying your trip.

Use Insect Repellent
One of the most effective ways to prevent bites is by using insect repellent. Look for repellents containing:
- DEET (20–50% concentration)
- Picaridin (also known as icaridin)
- Oil of lemon eucalyptus (OLE or PMD)
- Apply repellent to all exposed skin and reapply as directed (especially if sweating or after swimming).
- When also using sunscreen, apply sunscreen first, then repellent.
Dress to Protect
Wearing the right clothing can act as a physical barrier against mosquito bites.
- Wear long-sleeved shirts, long pants, and socks in mosquito-prone areas.
- Choose light-coloured clothing (mosquitoes are attracted to dark colours).
- Treat clothing and gear with permethrin, an insecticide that remains effective through multiple washes.
Sleep Safely
Some mosquitoes, like those that spread malaria, are most active at night, making nighttime protection especially important.
- Sleep under a mosquito net if your room isn’t well-screened or air-conditioned.
- Use insecticide-treated bed nets for extra protection.
- Keep windows and doors closed or screened.
Eliminate Mosquito Habitats
If you’re staying in one place for a while:
- Avoid standing water around your lodging (flowerpots, buckets, puddles).
- Keep containers covered and encourage local cleanup efforts.
Get Vaccinated or Take Preventive Medications
Some mosquito-borne illnesses can be prevented through vaccines or medications.
- Yellow fever vaccine: Required for entry into certain countries.
- Japanese encephalitis vaccine: Recommended for long stays or rural travel in Asia.
- Malaria prophylaxis: Pills like atovaquone-proguanil, doxycycline, or mefloquine may be prescribed based on your travel plans.
