To prevent rice weevils from breeding, you can refer to the following tips.
Use garlic, pepper, star anise
Rice weevils are very sensitive to strong-smelling spices such as garlic, pepper, star anise. You just need to put the spices in a small bag made of muslin or loose-grained fabric and drop it into the rice bin. The smell of the spices will scare the weevils and make them run away.
Note that these spices will lose their smell after a period of use. To maintain their effectiveness, you need to replace the spice bag with a new one.
Use dried orange and tangerine peels
After eating oranges and tangerines, don't rush to throw away the peels. Dry them in the sun or in a dryer and then put them in the rice bin. The essential oil from the orange peel will make everything run away and not dare to attack the rice bin again.
Not only that, the pleasant aroma of orange and tangerine peels can blend into the rice, making the rice more delicious.
Using salt
White salt is also effective and safe in repelling weevils. You just need to sprinkle a little white salt into the rice bin, the weevils will find a way to run away if they eat the salt.
Note, do not use too much salt because this spice can make the rice smell bad and easily get damp.
Use white wine
If you do not want the rice to have the pungent smell of spices, you can put a glass of white wine about 50g in the rice bin. Note, make sure the mouth of the glass is not covered, the glass must be higher than the rice surface.
Wine has antibacterial properties and evaporates more easily, so it will not affect the natural flavor of the rice.
Store rice in the refrigerator
The low temperature in the refrigerator will help kill and prevent weevil eggs from growing and developing. You just need to put the rice in a plastic bag or sealed box and leave it in the refrigerator for 4-5 days.
Notes when storing rice
Even if you leave the rice alone or add spices as above to prevent weevils, you also need to make sure the rice in the box/box is dry. Place the rice container in a high, cool place. Absolutely do not place rice in a humid place or exposed to sunlight. Damp rice is very susceptible to mold, affecting the quality of the rice, not good for health.
The lid of the rice container needs to be tightly closed after each use to prevent the rice from getting damp as well as insects attacking the rice.
