"Infest" refers to the presence of a large number of pests or unwanted organisms in a particular area, often causing harm or disruption. This term is commonly used in relation to insects, rodents, or other animals that invade homes, gardens, or agricultural fields, leading to potential damage to property or crops. In the context of pest control, infestations can be managed through various methods, including chemical treatments, traps, and natural predators. Effective management is essential to prevent the spread of these pests and to protect both human health and the environment.
