Mosquitoes in Mauritius and how to protect yourself

Pack mosquito repellent alongside your sunscreen for Mauritius. A few everyday habits can reduce bites, whether you are spending the day outside or relaxing at your accommodation. Protect yourself during the day as well as in the evening. The mosquitoes that transmit dengue and chikungunya mainly bite during daylight hours.

What is the health risk in Mauritius?

TravelHealthPro identifies a risk of dengue and chikungunya in Mauritius, but no malaria risk. That distinction matters. No malaria risk does not mean there is no reason to prevent mosquito bites. Outbreak conditions can change, so check the official country advice again shortly before departure. TravelHealthPro

Where are mosquitoes more likely in Mauritius?

Look at the immediate surroundings of your accommodation, not only the coast or district. A Mauritian mosquito survey published in 2024 found Aedes albopictus in almost all surveyed localities. At the airport and seaport, water-filled plant saucers, small containers, buckets and drums provided breeding sites; used tyres were particularly productive. These observations describe mosquito habitats, not the likelihood of a traveller catching an infection.

For a practical check at a villa, guesthouse or hotel, look for water left in plant saucers, uncovered buckets and discarded containers near your room or terrace. Report these to your host. A beachfront address alone tells you little about these small breeding sites. Pack repellent for everyday outings as well as nature walks.

Which areas have had reported disease clusters?

Mauritius’s parliamentary record of 12 May 2026 mentions chikungunya clusters in Plaines Wilhems, Port Louis and Black River.

This is a dated outbreak report, not a current mosquito-density map or a permanent ranking of districts. It does not establish which resort has the most mosquitoes today, or mean that other areas are free of risk. Before departure, check the latest destination health advice and follow any local health notices during your stay.

How does the season affect your precautions?

Mauritius has a warm, humid summer from November to April, with a cooler, drier winter from June to September.

After showers, check whether the containers around your accommodation have filled with water. These seasonal averages are not a forecast of mosquito numbers or disease outbreaks for your dates. Keep bite protection in your packing list throughout the year. For accommodation, check window screens and air conditioning rather than relying on a promise of a mosquito-free location.

Prepare before you travel

Arrange a travel-health appointment ideally four to six weeks before departure, or sooner if you have a health condition. A last-minute appointment is still useful. Discuss your itinerary, routine vaccinations and any vaccines appropriate to your circumstances. Dengue and chikungunya vaccination decisions need an individual assessment under the recommendations in your country. They are not a substitute for bite prevention. TravelHealthPro

Check entry requirements for your full journey, including stopovers. Yellow fever documentation can depend on where you have travelled from. Arrange insurance that covers your planned activities, treatment and possible medical evacuation. Keep policy details and prescriptions accessible. FCDO health advice

Choose and apply repellent properly

Choose an authorised insect repellent with a proven active ingredient, such as DEET or icaridin, also called picaridin. A pharmacist can help you choose an age-appropriate product and concentration. Follow its label for application and reapplication, particularly after swimming or heavy sweating. Keep it in your day bag so it is available when you need it.

Use separate sunscreen and repellent products. Apply sunscreen first, then repellent. Apply repellent to exposed skin, not beneath clothing or onto broken skin. Do not spray directly onto the face. Apply it to your hands first and keep it away from eyes and mouth. Bracelets, garlic and vitamin B are not reliable mosquito protection. CDC bite-prevention guidance

Add protection during outings and at your accommodation

Bring loose long sleeves and trousers as well as repellent. Use screened rooms or air conditioning where available, and a mosquito net when the sleeping space is not adequately protected. Avoid leaving containers of standing water around your accommodation. If you use clothing treated with permethrin, follow the instructions and never apply a clothing-treatment product directly to skin. CDC prevention advice

Do not reserve protection for sunset or assume your hotel or chosen coast removes the need for it. For an excursion, pack repellent, sunscreen and covering clothes together. After a swim, check both products’ reapplication instructions before continuing your day.

Travelling with children or during pregnancy

Ask a healthcare professional about a suitable product for your child’s age, or for pregnancy or breastfeeding. Use covering clothing and mosquito netting over prams and baby carriers. An adult should apply a child’s repellent, avoiding hands, eyes, mouth and irritated skin. The CDC’s general prevention guidance advises against OLE or PMD repellents for children under three. Product approvals and age instructions vary between countries, so check the exact label. CDC advice for families

If you are bitten or feel unwell

For an ordinary itchy bite, wash the area, use a cool compress and try not to scratch. Ask a pharmacist about suitable itch relief. Seek medical advice promptly for fever, a rash or significant joint pain during or after your trip, and tell the clinician where and when you travelled. Bite care

Severe abdominal pain, persistent vomiting, bleeding or difficulty breathing need urgent medical care. With possible dengue, do not self-treat with aspirin or ibuprofen because they can increase bleeding risk. In Mauritius, call 114 or 999 for an ambulance. WHO dengue advice · Emergency contacts
