Poisonous spiders in Greece

Species, Distribution & Behaviour Tips

Greece is known for its nature, sunshine and beautiful beaches – but also for some spider species. Most are harmless, but a few can be venomous. For travellers, it’s important to know which species occur, how to recognise them and how to react in case of a bite.

1. Distribution of Venomous Spiders in Greece

Venomous spiders are rare in Greece and are mostly found in rural, rocky or forested areas. They are particularly active during the summer months when it’s warm and dry. Typical regions – just examples:

• Peloponnese: olive groves and rocky slopes

• Crete: coastal regions and rural areas

• Cyclades: such as Naxos and Paros

• Central Greece: forests and hills

2. Most Dangerous and Venomous Species for Humans

• Mediterranean Black Widow (Latrodectus tredecimguttatus)

  • Recognisable by its black body with red spots

  • Bite can cause severe pain, nausea and muscle cramps

  • Life-threatening only for children, elderly people or allergy sufferers. Seek medical attention.

• Sicarius spiders (less common, very rare)

  • Usually found in dry rock and sandy areas

  • Venom can cause skin necrosis, but bites are extremely rare

Most other spider species in Greece are generally harmless to humans.

3. Behaviour Tips and Prevention

• Shake out shoes before putting them on

• Wear gloves when gardening or collecting wood

• Briefly check beds and tents in rural areas

• Supervise children when they play outdoors

4. First Aid for Spider Bites

1. Stay calm

2. Clean the bite area with water and soap

3. Cool – apply ice or a cool compress

4. Seek medical help – immediately if severe symptoms such as shortness of breath, rapid heartbeat or nausea occur

5. Identification – if possible, take a picture of the spider

Most bites are harmless

5. Conclusion

Venomous spiders that are dangerous to humans are rare in Greece, but cautious behaviour helps avoid bites. For travellers, the risk is rather low
