Mosquito surge in Mexican cities amid rain and heat

Heavy rains combined with high summer temperatures are prompting a sharp rise in mosquitoes, flies and other urban pests across Mexican cities. Dr. Romero A. Saldaña Vázquez, an academic at the Institute of Environmental Research of IBERO Puebla, warned that standing water in drains, flower pots, vases and other household containers creates ideal breeding sites for mosquito larvae. He urged residents to eliminate water accumulations, manage waste properly, install window screens, keep doors and windows closed where possible, and discard solid waste promptly.

The expert also recommended avoiding outdoor exposure during peak mosquito activity—between 7:00‑9:00 a.m. and 6:00‑9:00 p.m.—and, when necessary, wearing long‑sleeved clothing and applying repellents. Some mosquito species can transmit diseases such as dengue, making preventive measures essential for public health during the rainy season.
