The tiger mosquito has made significant inroads this summer in the Valencia autonomous region, affecting 85% of the area. The mosquito, which can transmit diseases such as dengue, chikungunya, and Zika, is now present in 464 of the 542 towns in the region.
This situation has prompted an urgent call from the regional Ministry of Health, urging residents to assist in combating this plague.
Awareness campaign
The Generalitat (regional government) has launched the campaign “Invasion of the Tiger Mosquito” to raise awareness among the population about the dangers of the tiger mosquito and how to combat it. The campaign emphasises three key steps:
- Prevent stagnant water.
- Clean pet drinking bowls regularly.
- Clean drains and gutters.
These measures are crucial because 70% of breeding sites are found on private properties.
Protect yourself from bites
The tiger mosquito is particularly active during the early morning and late afternoon. To prevent bites, it is advised to avoid using perfumes, as these attract mosquitoes, and to regularly use insect repellents. For bites, doctors recommend using iodine or corticosteroids to reduce itching and redness.
Innovative control methods
In addition to raising awareness, the Health Department is implementing a special program to assist affected municipalities in controlling the tiger mosquito. A notable measure is the release of sterile male tiger mosquitoes. These mate with wild females, resulting in infertile eggs and a reduction in the mosquito population. This method has already led to a 75% decrease in breeding sites in cities such as Torrent, Paterna, and Sagunto.
Community effort is essential
Ramon Torra, manager of the AMB, underscores the necessity of cooperation between the government and citizens to combat the spread of the tiger mosquito. By working together and following the recommended preventive measures, residents of the Comunidad Valenciana can help reduce the health risks associated with the presence of the tiger mosquito.
The tiger mosquito in Spain
The invasion of the tiger mosquito, also known as Aedes albopictus, in Spain poses significant risks. One of the greatest dangers is the transmission of severe viral diseases such as dengue, Zika, chikungunya, and yellow fever. These mosquitoes can cause more painful bites than ordinary mosquitoes, leading to more intense allergic reactions. Since the first detection in Catalonia in 2004, the tiger mosquito has rapidly spread to more than 40 provinces in Spain. Climate change also plays a role, with milder winters and higher temperatures enhancing the survival and reproduction of the mosquito. It is therefore essential to take preventive measures to limit the spread of the tiger mosquito and the associated health risks.
