Excuse me, what kind of bug is this? Living alone at night is really scary.
Spray pesticides continuously for four or five days, not just on conspicuous surfaces. Pay attention to the dead corners that usually come from those corners and are most likely to provide them with "territory" Spray carefully. Close the doors and windows after spraying, then go out and open the doors and windows when you come back at night. The pesticide disappeared after spraying for four or five days.
