Scorpion activity rises in Mexico City; prevention guide and high-risk areas

Mexico City is experiencing a surge in scorpion activity, a natural phenomenon intensified by the recent combination of rainfall and high seasonal temperatures. This weather pattern is driving scorpions from their usual hiding places, increasing the likelihood of encounters in residential areas and public transport.

The Secretariat of Health notes that heat and humidity create ideal conditions for scorpion reproduction. These conditions "force specimens to seek refuge, water, and food in urban areas," as their natural habitats are altered by the climate. The southern and eastern parts of the metropolitan area are most affected, with Tlalpan, Xochimilco, Magdalena Contreras, Milpa Alta, and Álvaro Obregón reporting the highest number of sightings. These areas often feature rocky terrain and denser vegetation, which support scorpion colonies.

While the most common native species in the capital, Vaejovis mexicanus and Vaejovis granulatus, have venom of low toxicity, experts warn of increased risk from accidentally introduced species from neighboring states like Morelos or Guerrero. These more dangerous scorpions can enter the city through moving households or plant transport.

To reduce the risk of stings and prevent scorpions from entering homes, authorities emphasize rigorous cleaning habits and physical barriers. Key self-care measures include thoroughly shaking out bedding and clothing, inspecting shoes before wearing them, and avoiding the accumulation of debris in yards and gardens, which serve as ideal breeding grounds. Installing screens and sealing cracks in walls and ceilings also helps prevent entry. The Secretariat of Health stresses that "domestic cleaning and the elimination of their hiding places are the most effective tools."
