Be careful, the ticks are there, and with them, the risk of contracting Lyme disease in the event of a sting.

The high temperatures that arrive this week are conducive to walks in grassy or forest areas. But beware, ticks hide there and are sometimes even found in gardens.

The National Research Institute for Agriculture, Food and the Environment (Inrae) has published a map showing the areas of France most favorable to the installation of ticks. We take stock for the Lorraine.

The very high risk over a major part of the region

To draw up its map, Inrae relied on data related to four factors: the climateI’altitudeI’land use as well as presence of guests for their meals. The institute then assigned a tick-friendly habitat score (HSI, or Habitat Suitability Index).

It is possible to observe that on a country scale, the four departments of Lorraine have a score considered to be “very high” (this being between 0.73 and 1, i.e. the values the highest).

In detail for our region, the central part of the Meuse has a high density. In Meurthe et Moselleit is especially the region of Nancy who is affected by this phenomenon. In Mosellethe most numerous habitats are located in the countries of bitch and of Sarrebourg. Finally, it is the western part of the Vosges who is the most concerned in the department.
