The responsibilities of an exterminator, also called a pest control worker, include identifying the pest problem, using pesticides, or choosing, mixing, and applying a chemical solution to get rid of pests such as rodents, termites, cockroaches, bed bugs, and more. Other strategies include setting mechanical traps and placing bait, and then removing dead animals after the process is complete. In this role, you ensure that all people evacuate residences or buildings while any chemical spraying occurs, that the air quality is back to normal, and that pesticides are cleaned up before reentering. Other duties include inspecting the outside of the building to determine the invasion site of the pests and drilling into walls to access infested areas.
