Pests are unwanted organisms that can cause harm to plants, animals, and even humans. They often include insects like cockroaches, ants, and mosquitoes, which can invade homes and gardens. Pests can damage crops, spread diseases, and create discomfort in our living spaces. Controlling pests is important for maintaining a healthy environment. Methods like using pesticides, setting traps, or introducing natural predators can help manage pest populations. Keeping homes clean and sealing entry points can also prevent pests from becoming a problem. Understanding pests and their behavior is key to effective pest management.
