There may be many reasons for cockroaches in the room. The following are some common reasons:
1. Incomplete cleaning: Cockroaches like to live in damp, dim and dirty environment. If the room is not cleaned frequently or is not cleaned thoroughly, it is easy to become a habitat for cockroaches.
2. Food residue: Cockroaches are omnivorous animals. They can eat many things, including human food residue. If there are food residues in the room that are not cleaned in time, it is easy to attract cockroaches to look for food.
3. High humidity: cockroaches need a humid environment to survive. If the humidity in the room is too high, it is easy to become a habitat for cockroaches.
4. Pipe leakage: cockroaches can enter the room through the water pipe. If the water pipe in the room leaks, it is easy to become a channel for cockroaches to enter.
5. The neighbor has cockroaches: if there are cockroaches in the neighbor's room, it is easy to enter their own room through the wall, floor and other ways.
To avoid cockroaches in the room, we can do the following:
1. Clean the room frequently, especially in the kitchen, bathroom and other places where cockroaches are easy to breed.
2. Timely clean up the food residue and sort the garbage.
3. Keep the room dry and ventilated.
4. Regularly check whether the water pipe leaks and repair it in time.
5. Keep good relations with neighbors and jointly control cockroaches.
