Residents and visitors to 10 departments across France – including Dordogne – are advised to be aware of the risk of viper bites, especially in the countryside.
The snakes proliferate when the weather is warm and wet, with periods of rainfall followed by humidity and mild temperatures, states the Modes et Travaux website, citing reports that the ARS (Agence Régionale de Santé) and firefighters SDIS saw a rise in the number of viper bites last year.
The same situation is looking increasingly likely for 2026, it warns.
Vipers are especially active after rain followed by warm temperatures, and are commonly found in dry, rocky or wooded habitats. They tend to be quite short and ‘stocky’, and have a zigzag-like pattern on their backs, states the Wildlife in France website. The most common type of viper in France is the asp viper (Vipera aspis).

How to reduce the risk of viper bites
Authorities recommend taking certain steps to reduce the risk of bites:
Wear sturdy, closed shoes when you are out in nature
Stick to clear paths rather than walking through long grass or thick bushes, especially after rain
Be alert around piles of damp wood or rocks
Don’t reach out to wood or rocks without checking first
Keep an eye on pets, as they can get bitten too, and may be less cautious
Vipers usually prefer to stay hidden, and will only lash out if they are disturbed or threatened. It is recommended to stay at least one metre or more away from a viper to prevent a bite.
What if I get bitten by a viper (or any snake)?
If you receive a snake bite, authorities recommend taking the following action:
Call 15 immediately to call the emergency services. With quick intervention, most viper bites are not serious.
Do not apply a tourniquet or make an incision into the bite.
Despite the small risk they pose, vipers are a protected species in France, as they are important for biodiversity.
