1. reed screening method: In order to shorten the time of pest control, after removing the insects on the surface, you can use a sieve made of bamboo or wicker to screen out the insects in the rice. Finally, put it in a cool place for ventilation and drying to remove all kinds of bugs in rice noodles.

2. Sunbathing method: find a sunny day and take out the rice to bask in the sun. Mi Chong will naturally run away because of the high temperature. Pay attention to turning over when drying, so that the rice is heated evenly. But the sun-dried rice is dry, so just put more water when cooking.

Pepper pest control method: Pepper is a natural antioxidant with special fragrance and insect repellent effect. The specific method is to put 20 to 30 prickly ash into a pot, add a proper amount of water (suitable for soaking rice bags), put it on the fire to cook the smell of prickly ash, then leave the fire, put the rice bags into the prickly ash water, take them out to dry, and then pour the rice into the pockets.

In addition, several small packets of peppers are wrapped in gauze and placed on the top, middle and bottom of the rice bag. The bag mouth is tightly tied and placed in a cool and ventilated place to prevent Mi Chong.

4, plant ash moisture absorption preservation method: in the bottom of the rice jar, spread a layer of plant ash (it is best to put plant ash in a gauze bag and put it at the bottom of the jar), then pour in the dried and blown rice, cover the rice jar tightly, and put it in a cool, dry and ventilated place, which can be preserved for a long time. Fourth, kelp pest control and preservation method: dried kelp has strong moisture absorption ability, which has the function of killing insects and inhibiting mold.

When storing rice, rice and kelp are mixed at the ratio of 100 1. After about 10 days, take out the kelp and dry it thoroughly, and then put it back in the rice, so that it can be mildew-proof and insect-proof.

5. Put a few cloves of garlic in the middle or at both ends of the rice bag, or wrap some peppers in cloth or paper and put them in a rice container. Usually, the rice storage tank or barrel should be cleaned to prevent cordyceps pupae from hiding in it. Once you find Mi Chong, you can dry the rice in the shade and let the bugs fly away or climb out. The rice with insects can be eaten after it is removed.

Extended data:

Common cereals in supermarkets include rice, millet, glutinous rice, Redmi, black rice, corn, oats, buckwheat, flour and other varieties. Among the common coarse cereals, rice and millet, as raw grain foods, can generally be cooked and eaten directly; Processed grains such as wheat, corn and oats need to be ground into powder or rolled into pieces before they can be eaten.

Generally speaking, cereal products in supermarkets are mainly divided into packaged products and bulk products, among which, packaged products are rarely infected during the shelf life because of pretreatment; The occurrence of insects in grain mainly occurs in bulk grain and packaged grain after opening bags.

In summer, due to the high temperature and humidity of the environment, the dormant eggs in the grain began to stir. First, it hatches into a "white fat" larva, and after a long or short time, it degenerates into an adult and completes its life cycle.

Common grain insects are rice weevil and corn borer, among which rice weevil mainly grows in granular grains such as rice and millet, while corn borer is common in various grains.

Rice weevil, also known as weevil, belongs to Coleoptera weevil family and is the main pest of stored grain. Its adult is about the size of two sesame seeds, brown and black, with a long, pointed mouth and six feet. Common in rice and beans, the larvae are grayish white and about three to five millimeters long. Adults eat grains, and larvae eat the inside of grains. Harm rice, rice, wheat, corn, sorghum, etc.

The life history of the rice elephant is about 20-50 days. From late June to early July, the larvae hatch and eat into granules. The larval stage is about 30 days, and it pupates in the middle and late July. The pupal stage is 7- 10 days, and the adults emerge in early August.

The other is called Indian corn borer, which is distributed all over the world. Except Tibet, it is distributed in all provinces, cities and autonomous regions in China. Indian rice borer larvae are cylindrical, and adults have wings and can fly.

Indian corn borer larvae like to eat the embryo of grain, often spinning silk to connect grain with excrement, netting to seal its surface, making it agglomerate and deteriorate. Sometimes we will find objects like cobwebs in long-term stored grain, which is the "masterpiece" of Indian corn borer.

First of all, experts suggest improving storage conditions, keeping grain storage containers clean, preventing storage pests such as rice weevil from entering, and reducing pest opportunities. Insect control measures include the following:

1, grain storage tools should be clean and sealed. It is best to put the grain into jars, jars and jars, and cover them tightly. If you use a cloth bag, put a plastic bag outside the cloth bag and tie the bag tightly.

2. Soak the cloth bag in the boiled pepper water, then put the grain in the air-dried bag, then wrap some new peppers with gauze, put them on the top, middle and bottom of the grain respectively, and tie the bag mouth tightly. This can not only prevent mildew, but also repel insects.

3. Mix kelp and rice according to the weight ratio of 1: 100, and take out kelp every week to remove water, which can keep rice dry and not mildew, and can also kill Mi Chong.

4. Put a few crab shells, turtle shells or scallions in the storage box, or spread 1 inch thick plant ash, spread white paper or gauze, seal the container and put it in a dry and cool place, which can also achieve the purpose of preventing insects from eating.
