To meet the basic requirements, most states and provinces require that you are 18 years of age and have never been convicted of a crime, especially involving the environment. And It goes without saying that you should not have a fear of pests or where they live.
Each state and province has a department that regulates the requirements and licensing of exterminators, so you would need to complete an approved training program and get a license for the area in which you live. This also means fulfilling the requirements for the number of hours that you must work under the supervision of a licensed professional.
You will have to take a Core exam that will access your mastery of basic concepts. This will include safety procedures, knowing the rules and regulations, being able to mix the correct ratio of chemicals and knowing how to apply them. Identification of pests and how to eliminate the infestation will also be tested. You will also be given another exam that is more specific to the field that you would like to specialize in.
You will be given an exterminator's license after passing all the exams and requirements needed to satisfy the state or province you live in.
Exterminators who want to be self-employed must have liability insurance while those working for an organization must ensure that the company provides full liability insurance as it is required by law. Various industries that employ exterminators include medical and surgical hospitals, colleges, universities and professional schools; bakeries and the local government.
Besides these technical qualifications, being an exterminator also means that one should be comfortable with working in cramped spaces, including basements and attics. As exterminators can be exposed to harsh chemicals, they must fulfill the physical requirements as well. They must be knowledgeable about various protection techniques that are used to minimize exposure and should have proper training in dealing with an emergency.
As exterminators have to discuss a lot of subjects regarding infestations with the customer, they must also possess good communication and interpersonal skills.
A good driving record is also necessary as there will be much time spent on the road.
