1. What to do if there are small flying insects in the soil

1. Mosquito coils to kill insects: Mosquito coils can be used to kill small flying insects. The specific method is to evenly sprinkle the ashes of burnt mosquito coils on the soil surface, and then water it appropriately to melt the ashes into the soil, which will have an insecticidal effect. It can also be mixed in water and then poured into the soil.

2. Soak tobacco in water: You can take out the tobacco from the cigarette butt, about five or six pieces will be enough. When soaking it in water, use as much water as possible, otherwise the concentration will be too high. After the water turns yellow, you can water the plants. Just pour it on the soil, which can also have an insecticidal effect.

3. Expose the soil to the sun: If there are insects in the soil, you can take out the soil and expose it under strong light for a period of time. This way, the insects will run away by themselves and the insect eggs will be killed. If you find that the roots of the plant have been bitten by insects, cut off the bad roots, disinfect them and repot them.

2. Can eggshells be used as soil?

Eggshells can be used in the soil, but you must be careful about how to use them. They cannot be put directly into the soil. They must be processed first. Put the collected egg shells under strong light and expose them to the sun. After they are completely dried, grind them into powder and mix them into the soil. This is not only harmless, but also can supplement calcium carbonate for the plants, which is beneficial to their growth and can promote flowering.
