What is the typical harborage site for the Oriental Cockroach?

The typical harborage site for the Oriental Cockroach is indeed damp places such as basements. This species thrives in environments that provide moisture and shelter, which is why you’re likely to find them in areas with high humidity. Basements often offer the dark, damp conditions that Oriental Cockroaches prefer, making them ideal spaces for these pests to reside and reproduce. They are attracted to decaying organic matter, which is frequently present in such moist environments.

In contrast, they are not found in dry environments or high altitudes, as these conditions do not meet their moisture needs. Warm temperatures do appeal to them for survival, but it is specifically the combination of warmth and moisture that leads them to areas like basements.
