Pesticides are chemicals that are made from a mixture of various substances. Their purpose is to kill, prevent, or mitigate pests in plants, homes, or any other area. But usually, pesticides are more associated with plants.

The word pesticide is a combination of two words: pest and cide. We know what pests are, and the term “cide” is a Latin word that means “to kill.”

Pests can destroy crops, their growth, fruits, and everything in plants. They eat leaves, stems, flowers, and buds of the plants and leave almost nothing.

Therefore, it is essential to deal with pests at the right time.

People usually prefer organic pesticides or natural pesticides for indoor plants. It is because they are living in their house, and they do not want to pollute the air and other areas.

Undoubtedly, pesticides are used for controlling pests, but when you apply them, a massive quantity of the pesticide also reaches some unwanted areas, such as nearby places, air, and water. Therefore, indoor farmers prefer organic pesticides.
