Bed bugs, walking caterpillars and tiger mosquitoes are increasingly colonizing our homes and gardens. How is it identified and eliminated?




tiger mosquito


It is a tropical mosquito known as the "tiger mosquito". When they bite someone who has the Zika virus, dengue fever, or chikungunya, they can transmit this infection. So it is as important to prevent the development of this mosquito as to protect yourself from it when you are sick.


No case of transmission of the virus by this mosquito has been observed in the Ile-de-France region.


Since disinfection of mosquito larvae or eggs is particularly harmful to the environment, it is only performed as a last resort if disease is present. Otherwise, no intervention and only vigilance of the population is effective.



How do you protect yourself from it?

The tiger mosquito colonizes all kinds of artificial containers and tanks as well as building items available in urban areas (vases, pots, barrels, cans, drains, drains, rain drains, gutters, terraces on plots, etc.) to lay their eggs.
