Background knowledge:

The insect with yellow eggs and the same shape and size as sesame is the fruit fly.

The English common name of fruit fly, fruit fly or vinegar fly, widely exists in temperate and tropical climates all over the world, and its staple food is rotten fruit, so it can be found in human habitats such as gardens and vegetable markets. In addition to the North and South Poles, at least 1000 species of fruit flies have been found, most of which feed on rotten fruits or plants, and a few only feed on fungi, tree sap or pollen.

Cut off its food source with pesticides (the kind that kills mosquitoes and flies), and try not to expose any peels and leftovers to the environment. Drosophila melanogaster sprayed with 500 times of 2.30% trichlorfon EC is very sensitive to pyrethroid pesticides, and general household pesticides are very effective.
