An exterminator's target can include a variety of pests, such as termites, roaches, ants, nests, centipedes, and rodents. Termites are small insects that feed on wood, and they can cause significant damage to buildings if left unchecked. Roaches are also small insects that can be found in homes and other buildings, and they can spread disease. Ants are small insects that live in colonies and can be found in many places, including homes. Nests are the homes of these insects, and they can be found in walls, ceilings, and other places. Centipedes are long, segmented insects that can be found in dark, damp places, and they can bite humans. Pests are any type of animal or insect that is considered a nuisance, and rodents are small mammals that can cause damage to property and spread disease. All of these creatures can be targeted by an exterminator.
