South Carolina sets its requirement by category, and the structural category is the one that matters. A Category 7 applicator, covering industrial, institutional, structural and health related pest control, must maintain comprehensive general liability financial responsibility of not less than $100,000 combined single limit, which must include both bodily injury and property damage coverage. Categories 3, 5 and 8, the ornamental, aquatic and public health side, sit lower at $50,000 with an annual aggregate claims limit of not less than $100,000.
Two details in the rule catch people out. Binders are explicitly not acceptable. You need a current public liability and property damage policy or a certificate of insurance issued by an insurance company, and the company has to be licensed to do business in South Carolina. And the carrier must give at least ten days written notice by certified mail to the Department as a condition precedent to cancellation. That is a specific obligation your insurer takes on, not a line an agent can type onto a certificate to make a filing go through.
The other South Carolina peculiarity is who needs a business license at all. The Department of Pesticide Regulation at Clemson requires a business license only for entities performing any activity in Category 7A, industrial, institutional, structural and health related pest control. A lawn and ornamental company operating purely in Category 3 does not carry the business license the way a household pest company does. The moment 7A work appears in the book, the business license, the Designated Certified Applicator and the financial responsibility filing all arrive together.
None of which is the real exposure. That sits in the CL-100. Only a Category 7A licensed applicator may issue the Official South Carolina Wood Infestation Report, and in a state where Formosan termites, drywood termites, powder post beetles and old house borers are all in play, that signature on a report tied to a closing is the most consequential thing most operators do all week.
