Roads were closed and people were asked to stay insider their homes as a massive fumigation process took place in Paris.
Southeast parts of the French capital have been frustrated with the increase in disease-carrying tiger mosquitoes.
It’s believed climate change is to blame for the mosquito’s rapid advance through northern Europe.
Pest control contactors sprayed insecticide in mosquito-breeding areas like trees and green spaces.
Tiger mosquitoes are originally from southeast Asia and other parts of the world where tropical weather is common. They carry viruses like dengue, chikungunya and zika.
The city’s deputy mayor Anne Souyris told BFM television that it’s the first time the northern parts of France are affected by the mosquito.
“It was a first in Paris, but it’s not the first in France. The south of France has been affected by tiger mosquitoes for some years.”
