So, they do not see in the dark like cats or owls. But they do see better than humans in low light.
How Do Cockroaches Find Their Way in the Dark?
Cockroaches use more than just their eyes. They have other senses to help them move.
- Antennae: Their long antennae sense touch, smell, and air movement.
- Leg sensors: They feel vibrations and textures through their legs.
- Body sensors: They detect changes in temperature and humidity.
These senses help cockroaches find food and avoid danger. Even in very dark places, cockroaches can move safely.
