Torrent attacks cockroaches with second disinsection campaign

Published on 2026-07-04 | Translated from Spanish

The Torrent City Council has launched the second sewer disinsectization campaign to curb the proliferation of cockroaches during the summer. The work covers 270 kilometers of network and more than 10,000 wells. After the application, a temporary increase in surface insects is normal, but the result will be fewer pests and better sanitation in the neighborhoods.

How the treatment works on 270 kilometers of sewers 🛠️

The technique applied is an insecticidal fogging that acts directly on the colonies in the sanitation system. The product, of low toxicity to humans and pets, is introduced via pressure equipment into the manholes. The 270-kilometer network is treated by sectors to ensure full coverage. The key is the time of year: just before temperatures rise, when cockroaches begin to reproduce. The result is a significant reduction of the population in urban areas.

Cockroaches on the surface: the awkward moment before the calm 😅

The funniest part of this campaign is that, right after the treatment, the cockroaches decide to make an express visit to the sidewalk. As if they were neighbors complaining about the smell, they stampede out to show their displeasure. But don't be alarmed: it's their swan song. In a few days, the neighborhood returns to normal and you can walk without looking like a contestant on a survival reality show. Help by reporting incidents and don't invite them to dinner.
