A pest repellent is a substance, product, or method used to keep pests away from a specific area without necessarily killing them. Pests include insects (mosquitoes, ants, cockroaches), rodents (rats, mice), and other unwanted organisms that can damage crops, food, homes, or cause diseases. Pest repellents work by producing smells, tastes, or chemicals that pests find unpleasant, forcing them to stay away.
