Indiana Pest Control License Requirements

Indiana's pest control industry is uniquely regulated by the Office of Indiana State Chemist (OISC), which operates through Purdue University. OISC oversees the certification of commercial pesticide applicators and the licensing of pest control businesses throughout the state.

Indiana requires all individuals applying restricted-use pesticides commercially to be certified, and pest control businesses must hold valid licenses. The state offers multiple categories of certification to cover various pest management specialties, from structural pest control to public health pest management.

Indiana certification exams are administered by OISC at Purdue University and at various testing locations throughout the state. The core exam covers pesticide safety, environmental protection, label comprehension, and Indiana laws. Category exams cover specialized topics for each certification area.

A minimum score of 70% is required to pass. Exams are offered regularly throughout the year. Purdue Extension provides comprehensive training programs and study materials that are highly recommended for exam preparation.

Registered Technicians may begin work immediately under the direct supervision of a certified applicator. Certified Applicator certification is obtained through examination without a strict experience prerequisite, though practical experience is recommended for exam success.

No specific degree is required. Purdue University Extension offers excellent training programs, workshops, and study guides for pest control certification. The Purdue Pesticide Programs provide both in-person and online training options to help applicants prepare for examinations.

Indiana pest control licensing fees include: Certified Applicator exam: $50. Business license: $100 annually. Registered Technician registration: $25. Category exam fee: $25 each. Triennial renewal: $50. Late renewal penalty: $25.

Indiana commercial applicator certifications are valid for 5 years. Renewal requires completion of approved continuing education or re-examination. Business licenses must be renewed annually. OISC and Purdue Extension offer numerous CEU opportunities throughout the year.

Indiana requires pest control businesses to maintain general liability insurance of at least $300,000 per occurrence. Workers' compensation insurance is required for businesses with employees. Proof of insurance must be provided to OISC as part of the business license application.

Indiana considers reciprocity with other states on a case-by-case basis through OISC. Applicants with valid certifications from states with equivalent programs may receive credit toward Indiana certification. Indiana's laws and regulations exam is typically required regardless of out-of-state credentials.
