Connecticut Pest Control License Requirements

Connecticut regulates pest control through the Department of Energy and Environmental Protection (DEEP). The state requires commercial pesticide applicators to be certified and pest control businesses to hold valid registrations. Connecticut places strong emphasis on environmental protection and integrated pest management.

With its dense suburban communities and older housing stock, Connecticut faces significant pest challenges including termites, bed bugs, and wildlife conflicts. The state's licensing program ensures that pest control operators are well-trained in both effective and environmentally responsible pest management techniques.

Connecticut certification exams are administered by DEEP at scheduled testing sessions throughout the state. The core exam covers pesticide safety, label comprehension, environmental protection, Connecticut laws, and integrated pest management principles. Category exams are specific to the type of pest control being performed.

A minimum score of 70% is required to pass. Exams are typically offered monthly. Study materials are available through the University of Connecticut Cooperative Extension System. Applicants who fail may retake the exam at the next scheduled testing date.

Registered Technicians may begin work immediately under direct supervision. Operational Commercial Applicator certification requires passing exams but has no strict experience requirement. Supervisory certification requires a minimum of 2 years of experience as a certified operational commercial applicator.

A high school diploma or GED is required. The University of Connecticut Cooperative Extension System offers training programs and workshops that prepare applicants for certification exams. DEEP also provides study guides and reference materials to assist with exam preparation.

Connecticut pest control licensing fees include: Commercial Applicator certification: $100. Supervisory certification: $120. Business registration: $250 annually. Technician registration: $30. Exam retake fee: $50. Annual renewal: $100.

Connecticut commercial applicator certifications must be renewed annually. Renewal requires completion of 8 continuing education credits per year, including credits in core safety topics and category-specific training. DEEP-approved courses are offered by various providers including the UConn Extension.

Connecticut requires pest control businesses to maintain general liability insurance of at least $500,000 per occurrence and $1,000,000 aggregate. Companies must also carry workers' compensation insurance and may need additional coverage for specific services such as fumigation or termite work.

Connecticut participates in limited reciprocity with neighboring New England states. Applicants with valid certifications from states with equivalent programs may be eligible for expedited certification. However, all applicants must pass the Connecticut laws and regulations portion of the core exam.
