The 8 most dangerous animals in France

The Asian Hornet

Among the approximately 400 invasive species registered in France, the Asiatic hornet (Vespa velutina nigrithorax). These insects, around 2 cm in size, are a threat to honey bees. When they spot a beehive, they attack the occupants, decapitating them with their mandibles and taking only the protein-rich thorax.

But its sting is also particularly painful for humans. Many people are bitten every year, some even die from it.

The Black Widow

Her name makes spider haters shudder: the black widow of Europe. Also known as “Malmignatte” or “Mediterranean Black Widow”, this small black spider can be recognized by the 13 red dots on its abdomen. It is found in France throughout Corsica, the south and along the Atlantic coast.

It owes its sinister name to the fact that the females, which average 1.5 cm in size, eat the smaller males after mating. In addition, its Australian and American cousins ​​are extremely dangerous, their bites can be deadly.

The European black widow is less dangerous. While its sting is not fatal, it can still cause major health problems if left untreated.

the viper

The main species found in France are the viper, the Péliade viper, the Orsini viper and the Pyrenean viper (from Seoane). The bite of this snake, although rarely fatal (about one death per year), must inevitably make the person attacked go to the hospital, even if the viper has not expelled venom (we then speak of a “white bite”). An injection of antidote can be done.

the tick

The tick is on the rise. While the risk of stings used to be greatest in forests, wooded and wet areas, and tall prairie grasses, the risk now also exists in public and private gardens.

Problem, the mite attacks both animals and humans and can transmit diseases. The best known is Lyme disease. 15% of ticks carry the bacteria responsible for this disease.

To avoid puncture injuries, there are a few simple tips: wear light and covering clothing, closed-toe shoes, do not walk in tall grass, sit on a blanket rather than directly in the grass, and check your clothing regularly.

The mosquito

He is the nightmare of our summers: the mosquito! The “traditional” mosquito buzzes in our ears at night when the tiger mosquito is silent and diurnal. And take care of him. In addition to itchy pimples, the tiger mosquito (Aedes albopictus) is particularly dangerous because it can transmit viruses such as chikungunya, zika, or dengue fever.

the long live

If the big lively lives in deep waters, this is not the case with the small lively (Echiichthys vipera). This fish, which measures 10 to 18 cm, has settled on our coasts in the sand very close to the shore. The problem is that the little one has a formidable weapon: poisonous spikes on its dorsal fin. Woe to the swimmer unfortunate enough to step on it.

Although not usually fatal, its sting is extremely painful and requires treatment. Poison-related effects include nausea, severe headache, palpitations, fever, and dizziness.

Since the poison is thermolabile, you need to quickly heat the affected area.

The shark

Sharks are rarely seen in metropolitan France, but are plentiful in overseas territories. Thus, it is possible to encounter several species in the West Indies: the mako, the tiger shark and the bulldog shark. Attacks are rare.

On the other hand, they are more common on the island of La Réunion. The five species of sharks considered dangerous to humans are found there, with a greater likelihood of encountering a bulldog shark or a tiger shark that develop near shore. Further offshore live the mako shark, oceanic whitetip shark and great white shark, which prefer deeper or temperate waters. Most attacks affect surfers.


Coming from the same family as centipedes and woodlice, the centipede is an arthropod, more precisely a centipede, which in Guadeloupe is called the “millipede animal”. It is found in both the West Indies and southern metropolitan France.

It has two fangs under its head and venom glands just under its jaws to better bite the insects it devours. It is better not to disturb him, because the centipede will attack if he feels in danger. The consequences can be severe, depending on the area bitten or if the “victim” is a child. The bite is very painful and can cause swelling.
