Although scorpions, spiders, and snakes do not seek to attack humans, interactions with them can occur due to environmental factors and daily activities.
Urban growth, construction, farming, storms, and extreme temperatures alter natural habitats, displacing these animals towards backyards, sheds, homes, and campsites.
It is important to remember that they do not hunt or ambush: they react to a threat, such as being stepped on or accidentally trapped.
Scorpions in Argentina: risks and prevention
In the country, the genus Tityus, especially Tityus carrilloi, represents the greatest health concern.
- It is found in the north, center, Cuyo, and Litoral regions.
- Between 2020 and 2024, 32,681 cases of scorpionism were reported.
- In 2024, there were 7,034 confirmed cases, with 96% concentrated in the NOA and Center regions.
- Children under 4 years old are the most vulnerable group.
Prevention measures
To avoid stings, it is recommended to:
- Check clothing and shoes before wearing them.
- Avoid walking barefoot in high-risk areas.
- Seal cracks and use weather stripping in homes.
- Keep outdoor spaces clean.
Dangerous spiders in the country
The most concerning species belong to the genera:
- Latrodectus (“black widow”): neurotoxic venom, causes cramps and spasms.
- Loxosceles (“brown recluse”): causes necrosis and kidney damage in severe cases.
- Phoneutria (“banana spider”): aggressive, affects the nervous system.
How to prevent accidents
- Clean behind furniture and avoid clutter.
- Air out rooms and check dark spaces.

Poisonous snakes: the most dangerous ones
Argentina is home to 136 snake species, of which 19 are venomous. The most dangerous ones are:
- Big and small rattlesnakes (97% of cases).
- Rattlesnake, with neurotoxic venom.
- Coral snake, dangerous due to its effects on the nervous system.
Prevention and safety
- Avoid walking barefoot in rural areas.
- Wear high boots or gaiters in snake-prone areas.
- Avoid handling dead snakes.
Attention and treatment
The National Institute of Biological Production (ANLIS/Malbrán) produces and distributes antivenoms for the venom of these species.
In case of a bite or sting, it is recommended to immobilize the patient and seek immediate medical attention.
The balance between conservation and safety
Scorpions, spiders, and snakes play essential roles in the ecosystem, regulating populations of other species.
Prevention and understanding of their behaviors reduce risks and promote harmonious coexistence with nature.
