No department is spared

Unlike in previous years, no department is in green alert, ie the presence of the tiger mosquito is under surveillance or attested throughout France.

The cause is to be sought because of a particularly mild weather in recent months. Winter 2018-2019 was mild and even before the beginning of spring, the French experienced several very hot days, days favourable to the development of the small striped beast.

How to identify a tiger mosquito?

The tiger mosquito measures an average of 0.5 cm , its abdomen and legs are black and white striped , very contrasted. Its wings are usually black.

The tiger mosquito has a white line on the upper part of the thorax.

It is not very mobile, its flight is very slow , which makes it easy to crush. But unlike other mosquitoes, his flight is silent.

Finally, be aware that its sting is more painful than that of the common mosquito and can cause pimples like blisters.

It loves stagnant water

To prevent its proliferation, it is necessary to ban all stagnant water points  in which It loves to land. Remember to empty all remaining cups in gardens, watering cans and other containers. Think of children’s toys that often hang out after a day playing.
