1, the small flying insects on fruits are called fruit flies, and they also eat rotten and fermented food. When fruit is left for a long time, it will produce a gas which will attract small flying insects. Wash the fruit with salt water and soak it before eating. This is because salt water has the function of disinfection and sterilization, which can attract and prevent small flying insects.

2. Sprinkle some chopped onions, onions and garlic on the surface of the fruit. Small flying insects don't like the smell of onions, shallots and garlic, which can kill small flying insects;

3. Light some dried tangerine peel next to the fruit, which can effectively eliminate small flying insects and eliminate odor;

4, throw away the rotten fruit, clean up the fruit residue, so as not to make it rot and attract fruit flies.

5. Install some fly-killing lamps next to the fruit, which can be turned on during the day and at night, which can eliminate the small flying insects that have been produced and also play a role in sterilization;

6. Put a fly board next to the fruit. The smell emitted by the fly-sticking board will attract more small flying insects, and then the small flying insects will stick to the fly-sticking board, which can well eliminate the small flying insects;

7. Seal the fruit with plastic wrap or plastic bag. You'd better eat fruit now. If you can't finish it, you should keep it fresh in the refrigerator. At high temperature, fruits are particularly attractive to insects, so if you can't finish eating them, put them in the refrigerator.
