Cockroaches are not afraid of water. Cockroaches, also known as cockroaches, are the oldest and most successful insect group in the world. Cockroaches have strong vitality and adaptability and are widely distributed in all corners of the world. It is worth mentioning that a cockroach whose head is taken off by humans can survive for 9 days, and the cause of death after 9 days is excessive hunger and thirst.
Cockroaches like to live in warm, humid, food rich and multi gap places, which are the four basic conditions for their breeding. All buildings where people live and live generally have these conditions, so cockroaches have become pests that infringe on the health of thousands of households.
Cockroaches like darkness and are afraid of light. They lie low in the daytime and come out at night, which is also an important habit of cockroaches. During the day, they are hidden in dark and dark places, such as indoor furniture, cracks in walls, caves and corners, and piles of sundries. At night, especially after the lights are off and people sleep, they go out for activities, or look for food, or seek a spouse. Therefore, about 75% of the 24 hours of the day are at rest.
