2. Soak Myrica rubra in salt water for 10 minute, because Myrica rubra has no peel and is especially sweet, so fruit flies can easily lay eggs on it, and then slowly they will hatch larvae, so try not to put Myrica rubra in the refrigerator first, which will freeze the insects to death, and the dead insects will not bubble out even if they are put in salt water. This kind of bug is harmless to human body, so don't give up eating because of choking.
