Insect infestation occurs when a large number of insects invade a specific area, often causing damage or health risks. Common pests include termites, ants, and cockroaches, which can invade homes, gardens, and agricultural fields. These insects can reproduce quickly, leading to significant population growth and potential harm to structures or crops. Infestations can be identified by signs such as droppings, nests, or visible insects. Effective management often involves pest control methods, including traps, baits, and insecticides. Preventive measures, like sealing entry points and maintaining cleanliness, can help reduce the risk of infestations.
