If there are insects in corn flour, the following methods should be used to remove them:

1. After the rice flour is damaged by poplar leaves, move the corn flour into a dry and sealed container; Put the freshly picked poplar leaves in a container and seal them with corn flour. Four or five days later, when the storage container was opened, the larvae and eggs were found dead. Then filter the rice noodles with a dustpan or sieve and you can eat them.

2. Corn flour stored for a long time by freezing pest control method is the most susceptible to moth-eaten in summer, and the moth-eaten rate is low in winter. According to this situation, the surplus corn flour stored after winter is put into clean bags and sent to the freezer in batches, so that it can withstand the "cold winter" for 24 hours. The rice noodles treated in this way are not easy to be infected by insects after the arrival of summer. Probably Mi Chong and the mealworm couldn't resist the ruthlessness of the "cold winter" and died in the bud.

3. The cool ventilation method inserts chopsticks into the insect-eaten corn flour, and after the insects in the corn flour climb up, the insects are pulled out. Then, put the corn flour in a cool and ventilated place, and the insects deep in the corn flour will climb out of the high-temperature rice flour. This method is simple and convenient, but it takes a long time to kill insects.

4. In order to shorten the deinsectization time, after removing the insects on the surface, you can use a laundry basket made of bamboo or wicker to remove the insects from the rice flour; Screen out the insects in the rice with a sieve made of bamboo strips. Then, put it in a cool and ventilated place to dry, and all kinds of bugs in the corn flour can be removed.
