Italy is a biodiversity zone and home to more animal species than any other European country.
Considering Italy’s wide range of animal species, it behooves us to watch out for poisonous animals even as we enjoy the land’s beauty.
Italy is also the location of one of the world’s great cities, Rome, and is a favorite of visitors.
Italy attracts visitors with its great monuments and works of art, striking landscapes, unequaled cultural heritage, fascinating water bodies, and rich history.
The enabling ecosystem here supports the survival of many animals and provides a suitable environment for these animals to thrive.
Italy’s wildlife is so impressive that UNESCO declared the Dolomiti Bellunesi National Park a World Heritage Site in 2009.
Notwithstanding Italy’s rich beauty, it is important to watch out for some poisonous animals in this beautiful country, even as one explores it.
Although many of these poisonous animals do not represent a great risk to human life, except in cases of anaphylaxis—a severe allergy to the toxins of various venom—it is important to know about them.
Keep reading as we examine some poisonous animals in Italy.
Poisonous Animals in Italy
1. Scorpions
Scorpions are among the poisonous animals that live in Italy.
These creatures are a type of arachnid and can be seen on every continent worldwide besides Antarctica.
Scorpions have two pincers, eight legs, and a curved tail that ends with a venomous stinger. They usually use these for attack and defense.
Approximately 2,300 known species of scorpions exist globally and come in various sizes and shapes.
Of all these species, only a maximum of 50 scorpion species are fatal to humans. Good riddance! The scorpions found in Italy do not belong to this very poisonous species.
The scorpions are black and small, rarely growing beyond 30mm in length.
They are nocturnal and rarely seen during the day. Notwithstanding, they could venture inside through cracks and open doors.
When this happens, eliminate their food source and use household pest spray to keep them away.
Italy has about 5 to 7 species of scorpions with rather weak poisons. Although these scorpions are poisonous, their sting is usually not life-threatening.
Their sting here can be likened to a wasp or a bee sting, which is usually harmless, except in cases of people allergic to insect stings.
Scorpion attacks are rare in Italy. Nevertheless, if you are stung, you should consult a doctor.
But then, you can carry out the outlined simple first aid.
- Clean the affected area with soap and water to remove dirt and bacteria.
- Elevate the affected limb and apply a cold compress to soothe the swelling.
- You can also take some simple pain relief pills, and within 30 minutes, you should notice the pain beginning to subside.
If a child is stung or experiences further symptoms after this first aid, it is best to visit the hospital to be on the safe side.
2. Spiders
Spiders are among the poisonous animals in Italy. They are also a type of arachnid and are considered the largest order.
They are popular creatures known for their signature eight legs and chelicerae with fangs, which they use to inject venom.
Nevertheless, they are known as beneficial creatures in the ecosystem.
Over 40,000 spider species are currently known and can be found on every continent except Antarctica.
More than 500 species of these spiders are said to exist in Italy.
While plenty of spider species exist in Italy, only three carry venom toxic to humans. Since they are non-aggressive, it is very rare for them to attack humans.
However, while their bites are painful, spider bite fatalities are extremely rare in Italy.
Spiders come in different shapes and sizes, each with unique looks and characteristics.
Let’s briefly examine these three species of poisonous spiders in Italy.
a. The Mediterranean Black Widow Spider
Mediterranean Black Widow spider is known as Latrodectus tredecimguttatus scientifically but goes by the local name “Malmignatta.
The spider can be found in warmer climates in rural locations and farm fields.
They are rare to find near country houses, so if you visit this beautiful country, don’t worry because the probability of seeing it in your abode is slim.
This spider can be easily identified by its size, distinctive black thorax, and red spots on its abdomen.
Sometimes, the spots can be orange or yellow. They are small and measure about 1.5 centimeters long.
The bite from this spider is rarely fatal to humans. Nevertheless, it can be dangerous to children or adults weakened with preexisting illness or age.
Generally, though, their bite can induce fever, nausea, and vomiting, which can be unbearable.
Victims may also experience sweating, hallucinations, and muscle spasms. Hence, seeking medical attention immediately when one gets bitten is advisable.
b. Ragno Violino
Another poisonous spider in Italy is the ragno violino. This spider is scientifically known as Loxosceles rufescens but is commonly known by its Italian name—ragno violino.
As its name suggests, the spider has a body shaped like a violin and six eyes rather than 8.
Another name for this spider is the Mediterranean recluse spider because they are antisocial and prefer to lurk around in dark, enclosed spaces.
They can be brown or yellow and grow from seven to 10 millimeters in size.
The spiders can be found in Italy’s urban and rural environments but are not aggressive.
So, don’t get paranoid about them; if disturbed, they prefer to move away.
Although fatalities from ragno violino bites are rare, their venom has a necrotic effect on affected tissues.
The only recorded fatal case of a violin spider in Italy was the death of a woman in 2016 after being bitten by the spider on her middle finger.
On a more general note, though, their bite can cause pain or discomfort, with symptoms ranging from itching to swelling and mild to severe skin lesions.
Medical treatment is highly required once bitten.
c. Yellow Sac Spider
Yellow sac spider, known as Cheiracanthium inclusum scientifically, is also one of the venomous spiders in Italy. The spider can grow up to 20 mm long, with orange-red underbellies.
As the name implies, this spider has pale yellowbacks and does not spin a web but creates a flat silk sac at the place where it passes.
This sac may be located where a wall and ceiling converge or in a leaf.
The bite of yellow sac spiders can be hurtful. Their bite has the same effect as wasp stings—redness, itch, swelling, and burning—while their venom is neurotoxic and cytotoxic.
Severe reactions to the bite include headache and fever. Although bitten by a yellow sac spider can be painful, it is rarely life-threatening.
3. Red Scorpionfish
Red scorpion fish are not only among the poisonous animals in Italy but are also known to be among the most poisonous sea creatures because of their sharp, venomous spines.
Known scientifically as Scorpaena scrofa, its common name is red scorpion fish due to its appearance.
The fish is often bright red, but its coloration sometimes may range from light grey to bright red with blotches.
They live on hard, rocky bottoms at depths greater than 20 m but can sometimes be found at the water’s surface.
This creature has a tight body with toxic spines on its head. It has 11 to 17 dorsal spines and pectoral fins with well-developed rays.
The spines are connected to venom glands that produce a very painful sting. The sting can cause intense pain and swelling that last for half a day.
Sometimes, the sting can cause loss of consciousness, dizziness, and hypotension.
The venom is said to spread quickly to other parts of the body, requiring prompt medical attention.
However, one can lessen the poison by heat by immersing the affected area in very hot water for first aid.
4. Weever Fish
Weever Fish is also one of the poisonous animals in Italy and easily included among the most dangerous fish at sea.
They can be seen in the Atlantic, Mediterranean, North, and other coastal regions on the bottom of river and sea beds.
They are nearly impossible to spot because they usually bury their bodies in mud and silt in shallow sandy water near the shore, and humans who step on them get stung.
These fish are a classic example of the saying “looks can be deceiving” because they look harmless, while in reality, they are not.
Weever fish are poisonous because they possess toxic dorsal spines that measure up to 2.5 centimeters in length, which they use to inject their venom into their victims.
A common place to get stung by a weever fish is the foot. Once this occurs, one would know because the pain from their sting, often described as a burning and crushing feeling, is instant.
Symptoms from their sting include itching, dizziness, nausea, fever, low blood pressure, swelling, headaches, fainting, or seizures.
The pain can be very uncomfortable, and medical attention should be sought immediately.
However, you can do DIY treatment to reduce the pain by following these steps:
- Check for spines and remove them with tweezers.
- Immerse the affected area in hot water for 30-60 minutes. Keep topping the water to maintain the temperature. Note that you can stick with water from 40 C / 104 F. The heat will help cook out the venom, rendering it harmless and less painful.
- Squeeze the wound to bleed out the venom.
- Wash the affected area with warm water and soap and rinse with fresh water.
That treatment should do, but you can always seek further medical attention for the best result.
5. Vipers
Vipers are a family of snakes found worldwide except in Hawaii, Madagascar, Antarctica, Australia, and other isolated islands.
They are also among the poisonous animals in Italy. Four venomous vipers exist in Italy, of which three are potentially lethal to humans.
They can be found across the whole of Italy, except for Sardinia.
These creatures are evil and have long, hinged fangs at the fore of their mouths, which they use to inject venom.
This venom travels down through the teeth to be injected into prey as the viper bites, and this causes a very painful wound that can sometimes be fatal.
The severity of the viper’s bite depends on the species, but all vipers’ bites cause intense swelling, pain, and necrosis.
Hence, it is advisable to seek medical attention if a viper bites you. Let’s take a brief look at these venomous vipers.
a. Asp Viper
One of Italy’s most common poisonous vipers is the Asp Viper; it is little wonder it is also known as the common viper.
It belongs to the Viperidae family and is known as the ‘Asp”, ‘European Asp,’ ‘Aspic Viper’ and ‘Jura Viper.’
The males are a little slimmer than females and can grow up to 85 cm long, while the female is rarely longer than 75cm.
These creatures have signature broad, triangular-shaped heads with an upturned snout.
Their coloring varies from light grey to reddish-brown. They have various markings down the body, occasionally resembling a half-zigzag.
They can be found in Italy’s hilly and mountainous regions, where they can access warmth and water.
Their venom is very potent, though rarely fatal for humans. Nevertheless, around 4% of untreated cases do end with a fatality.
Hence, one must get an antidote immediately because it can turn fatal if not treated immediately.
Symptoms of its bites include acute pain, swelling and discoloration at the site of contact, paralysis, difficulty breathing, impaired vision, and difficulty swallowing.
b. Horned Viper
Another venomous viper in Italy is the horned viper. This viper is found mostly in northeast Italy and can grow 85-95 cm long.
As its name suggests, this viper has a distinctive single “horn” on its snout, which grows to a length of 5 mm and is soft and flexible.
Both male and female vipers have similar color patterns, but the female’s patterns are less distinct and contrasting.
The males have irregular dark brown, gray, or black marks. They also have a row of indistinct, dark (occasionally yellowish) spots that run along each side, sometimes joined in a wavy band.
These vipers are not aggressive and shy, except when provoked. If surprised, some may remain motionless and hiss loudly, whereas some hiss and then flee, and some will attempt to bite immediately.
Notwithstanding, its venom is potent and can damage the victim’s nervous system.
Hence, immediate medical attention is advised. Symptoms of horned viper bites include pain, swelling, fatigue, and discoloration, all of which may be immediate.
c. Vipera Ursinii
This viper, also known as the meadow viper, is considered a rare species in Italy and is in danger of extinction, but it can be found in some areas of the central Apennines.
It grows up to 50 cm long and is characterized by a thick body, narrow head, and a brown or black zig-zag stripe on its back. T
The viper hides within holes in the ground, rock cavities, and the dense tangle of junipers at the slightest sign of danger.
This viper, unlike its brethren, is a mildly venomous snake. Nevertheless, medical attention is advised if bitten.
6. Mosquitoes
There are about 3,620 species of mosquitoes known in the world.
Although these creatures are often associated with the tropics, about 60 can be found in Italy, especially in the high summer months when it gets humid and around large bodies of water. However, only 10 of these are interested in mosquito controllers.
Mosquitoes are also among the poisonous animals in Italy. They are insects with segmented bodies, wings, and an elongated sharp mouth. Their life-cycle comprises the egg, larva, pupa, and adult stages.
They are common insects that can inflict a small bite that usually results in local inflammation and itching at the contact site.
Apart from the bites, some species of these insects carry poisons that cause problems.
One of the most common is the pathogen carried by the female anopheles mosquito, which transmits Malaria- a very common enemy in Africa.
Although WHO declared Italy malaria-free fifty years ago, this is no longer true today.
There have been cases of imported Malaria in Italy recently due to increased international travel, climatic and environmental change, and migratory flows.
Apart from carrying Malaria, mosquitoes also carry different parasites and infections, such as Dengue, Zika virus, and West Nile virus.
There have been reported cases of the West Nile virus in Italy since the beginning of July 2022.
This virus causes West Nile fever and is spread by ordinary mosquito bites.
The good news is that the spread of this virus is rare in travelers and rarely results in fatalities.
Nevertheless, it is best to avoid mosquito bites. You can take insect repellent with you as you explore Italy.
But then, when stung, do not hesitate to seek medical attention.
