1. Open the doors and windows and let the bugs fly out by themselves.
2. Sweep it out gently with a broom.
Put a piece of sticky paper near the lamp, stick the bugs on it, and then wrap it in a plastic bag and throw it away.
If insects show interest in certain items, such as fruits, they can be put in the corner to attract insects and then drive them out of the window.
If the above methods can't solve the problem, you can consider using pesticides. But before using pesticides, please be sure to read the instructions to ensure safety.
Please note that for large insects that are not sure how to deal with them, it is best to contact professional insect control services for help.
