the essential Established for 10 years in the Toulouse region, the tiger mosquito continues to spread. Despite monthly mosquito control campaigns, some residents of Tournefeuille complain of an “unbearable” situation.
“It’s unlivable. It’s impossible to enjoy the garden or plan a barbecue!” explains with despair a resident of Tournefeuille on social networks. In a few hours, nearly twenty people replied that they were in the same situation. However, the municipality has been carrying out mosquito control campaigns every month between May and September, and has been doing so for several years.
Biological mosquito control
The monthly treatment is done with a selective bio-product that only attacks mosquitoes. Mosquito control is effective once morest eggs, larvae and nymphs, but not once morest adult mosquitoes. Chemicals are no longer used, “except in the case of dengue fever, but that has never happened in Tournefeuille”, specifies Bruno Lombardo, deputy mayor in charge of municipal heritage and works. The treatment is located at municipal stagnant water points, such as lakes, ponds and ditches. If it seems difficult to quantify the success of these mosquito eradications, Bruno Lombardo assures that this “prevents the explosion in the number of mosquitoes”.
Individuals to act
However, municipal mosquito control seems very insufficient. According to Toulouse Métropole, “80% of larval breeding sites are found with locals”. The fight once morest mosquitoes must therefore be carried out mainly by individuals, especially since mosquitoes live within a perimeter of thirty to one hundred meters around their place of birth. In this context, some Tournefeuillais advise on social networks to remove the water from the cups under the flower pots and to place sand there. It also seems essential to clean your gutters regularly. Finally, an Internet user reminds us that composts are mosquito nests. To avoid their proliferation, it is necessary to open your composter so that it dries and avoid putting your sugary food waste there.
Now present in 70% of France, the tiger mosquito continues to grow. Tournefeuille and its inhabitants are therefore not the only ones who have not found the parade.
