Black bugs appear on mung beans

If mung beans are not stored properly, they are prone to black bugs, especially in the hot summer. If the mung beans are damp, they are prone to black bugs. The scientific name of mung bean bugs is weevils, also known as oil bugs. This is a kind of small black bug that specializes in eating beans. Sometimes this kind of bugs can also appear in flour. When this kind of bugs appear, you can put the mung beans in the freezer for a few days.

Prevention and treatment suggestions

If you put the mung beans you bought in the freezer for a few days, they will not reproduce with insects in the future. You can also put the mung beans into an empty mineral water bottle, screw on the lid tightly, and it will stay fresh no matter how long it is stored and will not be infested with insects.

If the mung beans are infested with worms, an effective method is to put the infested mung beans together with the bag into the freezer or freezer of the refrigerator. Take them out after freezing for 24 hours and all the worms in the mung beans will be frozen to death. After being stored in natural conditions for a period of time, the frozen dead insects will all dry up. When washing the mung beans, the insects will all float on the water surface and can be easily rinsed clean.

Some people also suggest putting it in the sun to dry, but I don’t think that’s good for the food. If there are a lot of bugs, you can throw it away directly.

It is recommended to store various beans in sealed boxes and clean and disinfect the cabinet regularly. If placed in a plastic bag, it is not convenient for storage.

Never place the basket in an open position, as the green bean worms will grow and fly everywhere, especially on the windows.

Sieve the mung beans and dry them, add an appropriate amount of peanut oil or cottonseed oil and stir evenly to cover the surface of the mung beans with a layer of oil. This will prevent the insects from laying eggs on the beans. The eggs that have been laid will be killed within a few minutes because they are surrounded by oil.
