First, rice shops sell rice. Do you know anything about turnover operation? Let me tell you how Mi Chong appeared. Mi Chong didn't breed in rice from outside, but insects used to lay eggs among rice. When the humidity, temperature and rice quantity are sufficient, Mi Chong emerges from its shell. What the naked eye can see are white larvae, pupae and small black adults. This Mi Chong is characterized by rapid reproduction, and may have laid eggs when rice was still rice.
Midian escaped, avoiding the emergence of Mi Chong, because Midian is updating its rice stock every day, and it is possible that the rice that came two or three days ago will be sold out in one or two days, while it takes 7- 16 days for Mi Chong to start from egg to larva, and 7- 10 days for larva to adult. Let's just say that Midian hasn't stored rice for more than half a month, and basically just came here. I'm afraid I can't see a shadow.
Second, storing rice in this way will never cause insects. The root cause of Mi Chong is temperature and humidity, so as long as you control these two things well at home, you will basically avoid insects during eating. When buying rice, you must choose very dry rice, and you can't have a little moisture. After you buy it back, you must store it in a ventilated place. If you think the rice is not so dry after buying it, you can also spread it in a cool place.
In the north, most people have cold balconies at home. You can put the rice on the cold balcony. In winter, cold insects in special weather have no chance to hatch. In summer, the cold balcony is a good place for ventilation, and the temperature here is relatively stable. As long as it is not directly exposed to the sun, the temperature will generally not rise, so that the rice bought home can be effectively protected. By the way, remember not to put it in the kitchen, because the steam in the kitchen will be strong when cooking, which may cause the rice to be wet.
Third, in case the rice is infected with insects, it should be treated like this. If the rice really has bugs and it is visible to the naked eye, don't drag it out again. Hurry and take the rice to the rice shop for a little processing. Through the screening of the machine, the rice that has been eaten by insects can be picked out, so that the rice taken home will not be eaten by insects again. However, it is worth noting that there may be eggs in some rice at this time.
If you are particularly concerned, you can take out the rice and change something. The price of this kind of rice in Midian is really not very high, but it can still be exchanged for some money. It is not impossible to fill in some new good rice with the exchanged money.
Finally: Try not to buy too much rice and store it at home. Without it, there would be no worms.
