(1) Mosquito and other arthropod control programs will ensure that the application of pesticides are made only when necessary by determining a need in accordance with specific criteria that demonstrate a potential for a mosquito-borne disease outbreak or numbers of disease vector mosquitoes sufficient for disease transmission or defined levels of, or a quantifiable increase in numbers of pestiferous mosquitoes or other arthropods as defined by Florida Statutes § 388.011(1) To determine the need for applications of adulticides, at least one of the following criteria shall be met and documented by records:
