Where do street rats live? - briefly
In urban areas, they occupy sewer networks, subway tunnels, vacant structures, and the immediate vicinity of garbage containers and food outlets. These sites supply shelter, water, and ready access to nourishment.
Where do street rats live? - in detail
Urban rats occupy the most resource‑rich microhabitats within cities. Their presence centers on areas that provide shelter, water, and a steady food supply while limiting exposure to predators and human disturbance.
Typical sites include:
- Underground utilities such as sewer pipes, storm drains, and subway tunnels, where moisture and darkness create ideal nesting conditions.
- Vacant or poorly maintained structures, including abandoned buildings, basement crawl spaces, and wall voids, which offer insulation and protection from weather.
- Open‑air refuse zones, such as garbage collection points, dumpster rows, and littered alleys, where discarded food is readily accessible.
- Green spaces that intersect with built environments, like park edges, overgrown vacant lots, and riverbanks, which provide both cover and occasional foraging opportunities.
- Residential perimeters, especially around external garbage containers, compost piles, and pet feeding stations, where human activity inadvertently supplies sustenance.
Nesting preferences vary by species. The Norway rat (Rattus norvegicus) favors deep burrows in soft soil or concealed cavities within foundations, while the roof rat (Rattus rattus) selects elevated locations such as attics, rafters, and high‑placed vegetation.
Key factors determining habitat selection are:
- Proximity to consistent food sources.
- Availability of water or high humidity environments.
- Structural complexity that allows concealment from predators and human interference.
- Temperature moderation offered by insulated or subterranean spaces.
Population density peaks in districts with dense waste generation and aging infrastructure, often exceeding several hundred individuals per hectare. Control measures target these specific microhabitats by reducing accessible food, sealing entry points, and maintaining drainage systems to limit moisture accumulation.
