A plain-English walkthrough of getting certified in Connecticut — supervisory versus operator certification, the written (and oral) exams, what it costs, and how to study and pass. Unlike most states, Connecticut runs pesticide certification through the Department of Energy and Environmental Protection (DEEP) Pesticide Management Program, not an agriculture department.
You register through DEEP's e-License portal and pay a $200 exam fee, which gives you 90 days to test. Exams are delivered online by Everblue with remote proctoring (a small proctoring fee applies, then 60 days to take the exam). Pass the written exam and most supervisor categories add an oral exam — 20 to 30 minutes before a small board at DEEP in Hartford covering pest identification, regulations, and product choices. Retakes require a new application and fee, with at least 30 days between attempts.
By statute the certification fees are $285 for supervisory, $80 for operational, and $100 for private certification, on top of the $200-per-attempt exam fee — government employees applying as part of their job are fee-exempt. Certifications renew every five years (expiring January 31) with 12 continuing-education credits PER category for commercial supervisors and private applicators — hold several categories and you need 12 separate credits for each, since core credits count once rather than multiplying across categories. DEEP may certify applicators from states with substantially similar standards without examination. Confirm current fees and your category's CE requirement with DEEP.
Connecticut recertifies on a five-year cycle, with certifications expiring January 31 of the renewal year and email notices going out about 90 days ahead. Commercial supervisors and private applicators renew by earning 12 continuing-education credits per category — a key catch for multi-category holders, since you need 12 separate credits for EACH category and core credits count only once rather than filling several categories at once. You submit the credits (plus any outstanding annual use summaries) with the renewal, and DEEP accepts credits approved for pesticides in another state and category. Operational (junior operator) applicators work under a certified supervisor rather than carrying this credit load themselves. Confirm your per-category credit total with DEEP before January 31.
The Department of Energy and Environmental Protection (DEEP) Pesticide Management Program — Connecticut runs certification through its environmental agency rather than an agriculture department.
For most supervisory categories, yes. After passing the written exam you are scheduled for a 20-30 minute oral exam before board members at DEEP in Hartford, covering pest identification, regulations, and material covered in the study guides.
The exam fee is $200 per attempt (plus a small Everblue proctoring fee), and statutory certification fees are $285 supervisory, $80 operational, and $100 private. Government employees testing for their job duties are fee-exempt. Confirm current fees with DEEP.
With approved continuing education credits before your certificate expires — about 12 credit hours per licensing period for supervisory and private applicators. DEEP emails renewal information ahead of expiration.
