Pest control workers use chemicals and other methods to repel or destroy bugs and rodents.

Pest control workers locate and identify pests. They use their knowledge of pests' habits to select the best method to kill or drive them away. They often use a combination of methods at each site.

One method of pest control is the use of pesticides. Workers spray or dust chemicals into and over exposed areas. Pest control workers also use other methods. For example, they clean infested areas so that pests do not have a food supply. Workers may build physical barriers to keep pests out of buildings. Another method involves using baits to kill pests or prevent them from reproducing. Workers use traps or tools to trap, burn, or freeze pests.

There are three levels of pest control workers. Regardless of the level, all pest control workers drive trucks equipped with power spray equipment. They also clean work sites and record the work activities they perform.

Applicators

Applicators often specialize in one or more areas. Termite exterminators use chemicals and modify structures to get rid of termites. They drill holes and cut openings into buildings to treat infested areas. Fumigators control pests by using poisonous gases. They seal buildings spraying gases into infested areas. They monitor the buildings for leaking gas.

Certified pest control applicators perform many of the same tasks as technicians. They are permitted to apply all types of pesticides. They are licensed to train and supervise technicians in pesticide use.

Technicians

Pest control service technicians assist applicators. They identify problem areas and prepare buildings for the application of pesticides. They set up traps, dig trenches, and operate equipment. They may also make sales presentations to customers.

Supervisors

Pest control supervisors direct the work of service technicians and applicators and make sure they follow regulations. They are licensed to apply pesticides. They usually spend most of their time running the business. They also resolve problems with regulatory officials.
