Overview
- Residents across Buenos Aires’ metropolitan area and La Plata report large water bugs on balconies, patios and streets, with clusters noted in San Carlos, Los Hornos, Gonnet, City Bell and Villa Elisa.
- City environmental officials describe the surge as an “explosión demográfica,” not an invasion, and indicate it should recede once the weather shifts.
- The insects are aquatic hemipterans of the Belostomatidae family that normally live in shallow freshwater but can fly and are drawn to artificial lights, explaining their urban appearances.
- Authorities and specialists say the bugs do not transmit diseases, though they can deliver a painful bite if handled, so people should avoid direct contact.
- Guidance emphasizes clearing standing water, cleaning patios and drains, sealing gaps to prevent entry and avoiding indiscriminate insecticide use, with no public-health emergency declared.
