Worried about encountering mosquitos during your trip to Portugal? Fear not, as while there are mosquitoes in Portugal, they tend to be a nuisance only in certain regions, with the Algarve experiencing higher concentrations than other areas.
Despite their presence, mosquitoes generally don’t pose a significant disruption to your exploration of Portugal’s beauty, as these troublesome insects are typically found in humid and wooded areas.
Although Portugal’s stunning Algarve region has been identified as the only area at risk for tropical diseases transmitted by mosquitoes, a bit of preparation and preventive measures can ensure that you enjoy a safe and memorable trip.
Are Mosquitos a Problem in Algarve?
Yes and the extent of the problem varies depending on factors like the time of year and the location you’re in.
During the summer, when temperatures are higher and there is more standing water from rains or irrigation, mosquitoes are more prevalent. This is particularly true in areas near water bodies like ponds, marshes, or poorly drained areas.
However, the risk of mosquitos spreading diseases remains low, thanks to effective control measures.
Are Mosquitoes in Portugal Dangerous?
Generally no.
Although mosquito-borne diseases like dengue or malaria are not a typical concern for travellers to Portugal, climate change has caused warmer temperatures in the south of the country, leading to a better breeding environment for mosquitoes.
There have been historical cases of dengue outbreaks, such as the one on Madeira island in 2012, affecting over 2,000 people.
There might not be current cases of dengue, Zika, or chikungunya, but the presence of the mosquitoes that transmit them has caught the attention of the World Health Organisation (WHO). As a result, Portugal and other southern European nations are on alert for these potentially fatal diseases.
Newest research shows that in 2023 another potentially harmful mosquito, Aedes albopictus, also known as the Asian tiger mosquito, has been detected in Portugal for the first time.
Mosquitoes become most active when temperatures rise above 17ºC. If they bite you, the symptoms of diseases like dengue, Zika, and chikungunya could include high fevers, intense pain in your hands and feet, and overall exhaustion. While treatable when detected early, Zika can be particularly dangerous for developing babies.
To address this issue, experts at the Ricardo Jorge public health institute and ARS Algarve are devising strategies to eliminate these pesky insects and the diseases they carry. As you travel through Portugal, remember to take precautions like using mosquito repellent and wearing appropriate clothing to help guard against mosquito bites and the potential risks they bring.
How can I protect myself against mosquitos?
During the warmer summer months, there is an increased chance of encountering mosquitoes, so it’s essential to protect yourself against these pesky insects. Here are some ways to keep mosquitoes at bay:
- Dress appropriately: Wearing long-sleeved shirts and trousers is an effective way to minimise skin exposure and reduce the risk of mosquito bites.
- Use insect repellents: Apply a reliable insect repellent on exposed skin areas. There are various types available, such as DEET-based or natural repellents like citronella.
- Consider plugin repellents: To keep mosquitoes out of your accommodation, invest in a plugin repellent suitable for use in Portugal and keep windows and doors closed to prevent their entry.
- Citronella candles and other natural repellents: Use these outdoors to deter mosquitoes from your vicinity. They are cost-effective and easy to find in local supermarkets.
- Avoid stagnant water: Mosquitoes breed in standing water, so eliminate pooling water around your property by inspecting flower pots, bins, and old tyres. Removing the water source can reduce mosquito populations drastically.
- Invest in mosquito bracelets: These wristbands are popular and offer a convenient option for repelling mosquitoes. Some are specifically designed for children, providing a safe and chemical-free alternative.
