With the arrival of warm weather, between May and October, the activity of the tiger mosquito (Aedes albopictus), an invasive species that can cause annoyance with its bites and transmit diseases like Chikungunya, Dengue, and Zika, intensifies. In response, several municipalities in Garrotxa are undertaking actions within the framework of the Dipsalut Tiger Mosquito Program. This program combines technical interventions with public awareness campaigns. The Consell Comarcal, through the Consorci SIGMA, provides technical advice to municipalities that request it for managing control in public spaces and conducting informative actions.
An information point was set up in Plaça Rector Ferrer in Olot, where professionals from the mosquito control service provided citizens with necessary information about the species and prevention. Taking advantage of this outreach, mosquito netting was freely distributed to gardeners to cover drums and other water-collecting containers, as mosquito larvae develop in these breeding sites. Larvae require approximately seven days to grow in small stagnant water bodies, avoiding moving water or large water masses. The mosquito's life cycle is also influenced by climate and daylight hours, with active presence from May to October, although temperatures can alter this period.
Municipalities in Garrotxa have carried out preventive treatments in public drains throughout the summer to prevent them from becoming breeding grounds. These treatments use authorized and environmentally friendly larvicidal products. Critical points are also monitored, and municipalities receive advice on prevention plans, municipal ordinances, and communication through the Consorci SIGMA.
It is estimated that 80% of breeding sites are found in private spaces, such as patios, gardens, or balconies. Therefore, individual prevention is crucial, especially after rainfall. Recommendations include emptying or covering containers that collect water, keeping gutters clean, hermetically sealing tanks or covering them with mosquito netting, and removing old items outdoors that may retain water. Prevention also depends on the public.
