A pest is any organism that is considered a nuisance or harmful to humans, animals, or plants. Common examples include insects like cockroaches and mosquitoes, as well as rodents such as rats and mice. Pests can damage crops, spread diseases, and create unsanitary conditions, making them a concern in both urban and agricultural settings. Pests can be managed through various methods, including pesticides, traps, and natural predators. Integrated Pest Management (IPM) is a holistic approach that combines these strategies to minimize the impact of pests while being environmentally responsible. Understanding pest behavior and ecology is essential for effective control.
