They use chemicals and modify structures to eliminate and prevent termites. To treat infested areas, termite exterminators drill holes and cut openings into buildings to access infestations. To prevent further infestation, they modify foundations and dig holes and trenches around buildings. Some termite exterminators even repair structural damage caused by termites. Fumigators are applicators who control pests using poisonous gasses 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.
