Roaches, rats, mice, spiders, termites, fleas, ants, and beesfew people welcome them into their homes or offices. Unwanted creatures that infest households, buildings, or surrounding areas are pests that can pose serious risks to human health and safety. It is a pest control worker’s job to eliminate them.
Pest control workers locate, identify, destroy, control, and repel pests. They use their knowledge of pests’ biology and habits, along with an arsenal of pest management techniquesapplying chemicals, setting traps, operating equipment, and even modifying structuresto alleviate pest problems.
Part of pest control may require pesticide application. Pest control workers use two different types of pesticidesgeneral use and restricted use. General use pesticides are the most widely used and are readily available; in diluted concentrations they are available to the public. Restricted use pesticides are available only to certified professionals for controlling the most severe infestations. Their registration, labeling, and application are regulated by Federal law, interpreted by the U.S. Environmental Protection Agency (EPA), because of their potential harm to pest control workers, customers, and the environment.
Pesticides are not pest control workers’ only tool, however. Pest control workers increasingly use a combination of pest management techniques, known as integrated pest management. One method involves using proper sanitation and creating physical barriers, for pests cannot survive without food and will not infest a building if they cannot enter it. Another method involves using baits, some of which destroy the pests, and others that prevent them from reproducing. Yet another method involves using mechanical devices, such as traps, that remove pests from the immediate environment.
Integrated pest management is becoming popular for several reasons. First, pesticides can pose environmental and health risks. Second, some pests are becoming more resistant to pesticides in certain situations. Finally, an integrated pest management plan is more effective in the long term than use of a pesticide alone.
New technology has been introduced that allows pest control workers to conduct home inspections, mainly of termites, in much less time. The technology works by implanting microchips in baiting stations, which emit signals that can tell pest control workers if there is termite activity at one of the baiting stations. Workers pick up the signals using a device similar to a metal detector and it allows them to assess much more quickly whether termites are present.
Most pest control workers are employed as pest control technicians, applicators, or supervisors. Position titles vary by State, but the hierarchybased on training and responsibility requiredremains consistent.
Pest control technicians identify potential pest problems, conduct inspections, and design control strategies. They work directly with the customer. Some technicians require a higher level of training depending on their task. If certain products are used, the technician may be required to become a certified applicator.
Applicators that specialize in controlling termites are called termite control technicians. They use chemicals and modify structures to eliminate termites and prevent reinfestation. To treat infested areas, termite control technicians drill holes and cut openings into buildings to access infestations, install physical barriers, or bait systems around the structure. Some termite control technicians even repair structural damage caused by termites.
Fumigators are applicators who control pests using poisonous gases called fumigants. Fumigators pretreat infested buildings by examining, measuring, and sealing the buildings. Then, using cylinders, hoses, and valves, they fill structures with the proper amount and concentration of fumigant. They also monitor the premises during treatment for leaking gas. To prevent accidental fumigant exposure, fumigators padlock doors and post warning signs.
Pest control supervisors, also known as operators, direct service technicians and certified applicators. Supervisors are licensed to apply pesticides, but they usually are more involved in running the business. Supervisors are responsible for ensuring that employees obey rules regarding pesticide use, and they must resolve any problems that arise with regulatory officials or customers. Most States require each pest control establishment to have a supervisor; self-employed business owners usually are supervisors.
