Roaches prefer darkness because it helps them stay hidden from predators such as birds, lizards, and even humans. By moving at night, they reduce the risk of being seen and captured.

2. Searching for Food and Water

Roaches are scavengers that rely on food crumbs, garbage, and moisture to survive. Nighttime provides the perfect opportunity for them to explore kitchens, sinks, and trash bins without disturbance.

3. Sensitivity to Light

Most cockroach species are photophobic, meaning they avoid light. Bright environments make them feel threatened, so they naturally emerge in the dark when they feel safe.
