Cockroaches take over the streets when the thermometer exceeds thirty degrees

With the arrival of summer and temperatures above 30 degrees, sewer cockroaches emerge shamelessly to the surface. Colonies become active and roam freely across sidewalks, parks, and doorways. The plague gives no respite, and residents are already noticing a notable increase of these insects in urban areas. The heat accelerates their metabolism and drives them to seek food and water outside the pipes.

The science behind the invasion: thermoregulation and biological cycle 🧬

Cockroaches are ectotherms; their activity depends directly on ambient temperature. When the thermometer exceeds 30 degrees, their metabolism accelerates by 40% to 60%. This implies a greater need for food and faster reproduction. Females produce oothecae every 20 days instead of every 30. Additionally, the heat reduces sewer humidity, forcing them to migrate to cooler, more humid areas such as basements, garages, and homes. Drainage systems become highways for these insects.

The cockroach master plan: paid vacation in your kitchen 🏖️

While you take a breather on the terrace, cockroaches organize their vacation tour of your home. Without prior reservation or notice, they enter through the sink and settle into the pantry as if they had rented an Airbnb. They don't pay for electricity, they don't pay for water, and on top of that, they take the breadcrumbs. If you also leave the window open, consider that you have put out the welcome sign. They are silent guests, but very hungry and with no intention of leaving.
