A common question one hears on the streets of Buenos Aires these days is, oddly enough, “Do you have any repellent? The Argentine capital has an unprecedented number of mosquitoes, the appearance of which is a confluence of circumstances.
“It’s almost impossible to be in the parks near the river, they come in swarms,” complains Diego, a resident of Buenos Aires.
“I live in a high-rise, on the 29th floor, you’d think, what mosquitoes? But no, they get to me too. Before going to bed, I sprinkle myself with repellent and only then go to bed, otherwise, it’s impossible to sleep. And you can’t close the windows at all – it’s hot,” says Maria, sharing her experiences.
The insect that bothers the residents of the capital is the most common, typical for this area species of mosquito Aedes Albifasciatus, but this year the weather conditions were such that the increase in their number was explosive, explains the member
“The condition for their emergence was a long drought and then heavy rains in the region, which flooded the recesses in the ground, where the eggs are located. All stages of the mosquito (egg, larva, pupa) are aquatic. What happened? Many rural areas and park areas in cities, including Buenos Aires, were flooded at the same time, and it turned out that a large number of adults developed at the same time,”
In search of food, the mosquitoes flew into the city on their own or thanks to the winds. However, the residents of Buenos Aires did not have long to endure. “The number of insects has already begun to gradually decrease, it has been more than a week since their appearance, and these mosquitoes do not live longer than a month, and they need to lay eggs. They mostly prefer rural areas for this purpose … Many are already leaving the city (to continue their lineage),” the expert noted.
These mosquitoes are not carriers of dangerous diseases, but their bites can cause painful allergic reactions. However, regulating their numbers is not considered mandatory in Argentina – fumigation is costly and harmful to the environment, and mosquitoes themselves do not pose a threat to human health. Therefore, Buenos Aires residents should always have a stock of repellents at home.
