An insecticide is a type of chemical used to kill or control insects that can harm plants, animals, or humans. Farmers often use insecticides to protect their crops from pests, ensuring a healthy harvest. These chemicals can come in various forms, such as sprays, granules, or powders, and are designed to target specific insects while minimizing harm to other creatures. While insecticides can be effective, they also raise concerns about their impact on the environment and human health. Some people worry about the effects of insecticides on beneficial insects like bees and butterflies, which play crucial roles in pollination. Therefore, it's important to use insecticides responsibly and explore alternative pest control methods.
