The most common types of roaches include American, German, Oriental, and Brown-banded.

Roaches need for survival has made them intelligent insects. They know the light is not safe for them. Therefore, they appear during the night when the lights are off, and everyone has gone to sleep.

During the day, they hide in dark places. They know that if they appear during the day or when lights are not on during the night, they are more vulnerable to attacks from predators, including humans.

Even at night, the cockroaches only appear some hours after the lights are off. Often when they appear, they are nearly always in large numbers.

When the lights are off, cockroaches appear to exploit the numerous opportunities created for them by humans. Some of these opportunities include dirty utensils in the sink, food droppings on the floor, full garbage can, and pet food.

Often people prefer to do the dishes early in the morning. This is a huge opportunity for a roach to feed on your leftovers!

There is plenty of food for them to find during the night. In addition to these, there is minimum disturbance from predators.
