2, flies like to stop on smallpox, you can get some soap bubbles in a cup or pot, and then add some water to make the bubbles float on the water. Quietly put this container near the fly. When a fly senses danger, it will fall not far from smallpox-the process of run-up and take-off. Then, it just falls into the bubble, and you can toss it slowly.
3. You can also wrap cloves in cotton cloth or gauze and put them in any place where flies often haunt, which also has a threatening effect on flies like a door god. At this time, I will be surprised to find that those flies flying around suddenly disappeared. They hated the smell of cloves and ran away with a bang.
