It's because the flesh of the prune is exposed without the protection of the rind. Fruit flies like to bite the flesh without the peel, and it just so happens that prunes are the fruit fly's favorite. In addition, fruit flies in the process of eating prunes produce eggs, through the reproduction and development of eggs, and will breed a lot of white bugs.

Method one is the salt water immersion method. The white bugs in prunes are very afraid of salt water, and it is difficult to survive in salt water. If you use a high concentration of salt water to soak for half an hour, it can be very good to clean the white bugs on the prunes, and finally rinse with water.

Method two is the baking soda cleaning method. Mix baking soda with water, the concentration is high, pour into the prunes, let stand for about half an hour, and finally rinse with water.

Note that the direct rinsing of prunes with water only applies to prunes without worms, and prunes with worms are still recommended to be cleaned with the above method. To ensure that the prunes are clean and hygienic.
