It is easy for rice to grow insects if it is stored for a long time. Especially after it is stored for a long time and the temperature gradually rises, the rice may produce black "rice elephants" or small yellow-gray moths, which will seriously affect the rice. quality and appearance. The reason why rice grows bugs is because the storage temperature and humidity are suitable for the hatching and reproduction of these two bugs. The home storage environment is greatly affected by the outdoor temperature and humidity. Once the temperature and humidity reach the requirements for insect eggs to hatch, insects will naturally grow.

For these two small bugs, the requirements for humidity are not that high. The main factor that affects their incubation and activity is temperature. For example, if the rice storage temperature is above 20 degrees, these two kinds of bugs may be born. If the storage temperature exceeds 25 degrees, it is natural for insects to appear. For example, the rice, millet and other grains we store at home are stored openly in rice bags or some plastic barrels. The temperature inside the rice is greatly affected by the outside temperature. Moreover, we often store some vegetables or plant some flowers and other plants in our own homes, which is also one of the reasons why rice and other grains get bugs.

As for the fact that there are no bugs in the rice in the supermarket, you can observe it carefully. How much rice can be placed on the counter? Not much. Where are the other rice and grains? They are all placed in constant-temperature, low-temperature, and constant-humidity storage warehouses dedicated to storing grains. The temperature of the storage library generally does not exceed 15 degrees and is in a low-temperature storage state. This can not only effectively prevent insects, but also effectively preserve the freshness of rice and other grains, and is also very effective in ensuring the taste of rice and other grains.

So, you can store rice and other grains at home in the fresh-keeping layer of the refrigerator or freezer, and use low temperatures to inhibit the hatching of insect eggs; if possible, buy some plastic bags that can be vacuumed , dividing the grains into several bags for vacuum storage can also prevent rice and other grains from getting worms after being stored.
