If you have time, you'd better clean your room every day and then take out the garbage in time. Then spray, people can go out for a while. You can also put powder. If you do both, the bugs will gradually decrease. See what kind of bug it is, you can take your own photos, send them to customer service for a look, and buy the right pesticides. It'll be all right in a minute. This is my personal experience. You can try.
