Cancún, Quintana Roo — Extreme summer heat is driving snakes and opossums into Cancún’s residential areas, forcing firefighters to conduct wildlife rescues nearly every day, authorities said.
“The heat forces these animals to leave their natural habitat in search of water, shade, shelter, and food,” said Óscar Aguilar Aceves, director of the Benito Juárez Fire Department.
Reptiles, which depend on ambient temperature, often take refuge in patios, gardens, and inside homes. Their activity spikes significantly after rainfall, when they come out to hunt.
Neighborhoods With Most Snake Reports
Rescues occur across the city but are concentrated in peripheral areas with dense vegetation. The highest incidence is in regions 227, 236, and 260, as well as the irregular settlements of Avante and Tres Reyes.
Depending on the animal’s condition, snakes are either released directly into remote green areas or transferred to the Animal Welfare Department for veterinary checks.
Opossums: Dispelling Myths About Rabies
Opossums have become more common in the urban zone, especially in downtown Cancún, as their breeding season ends and food becomes scarce. Many are found injured.
“We find many of them hurt, and we need to say that these animals are not aggressive and do not have rabies. They are essential for controlling insect and small rodent pests,” Aguilar Aceves said.
Rescued marsupials are handed over to the nonprofit Tlacuatitlán for rehabilitation and eventual release.
Recommendations for Residents
The fire chief urged the public not to attempt to capture or kill wildlife, emphasizing that both snakes and opossums play a key ecological role in rodent control.
To reduce risks at home, officials recommend:
- Keeping patios clean and free of debris or trash.
- Sealing cracks and openings in homes.
- Supervising pets in open areas.
- If you spot a wild animal, keep your distance and call firefighters or civil protection immediately.
