Certification in Alaska is personal, not corporate. There is no separate pest control business permit issued by DEC: individuals certify under 18 AAC 90.300, which lists roughly twenty categories including structural pest control, ornamental and turf, public health, agricultural, forest, aerial, vertebrate pest control and the pesticide technician category. You pass the Core exam in all three sections plus at least one category exam at seventy percent or better, submit the $25 fee, and submit proof of insurance. An applicator working only on property they own or lease with non-fumigant products can designate as a private applicator and skip the insurance requirement, which is exactly why it does not help a commercial operator.
Initial certification runs one, two or three years depending on your exam scores, which is unusual enough that operators budget for it wrong. Recertification then runs three years and takes twelve approved continuing education units, plus the $25 fee and, again, proof of liability insurance. The coursework has to be finished before the current certification expires. Let it lapse and you are back to sitting exams rather than counting credits, and every day between is a day the company cannot legally take contract work.
Two other filings sit outside DEC. Alaska requires a state business license, currently $50 a year, for essentially any business operating in the state. And if your work crosses into construction, which exclusion, screening, crawlspace repair and structural remediation frequently do, contractor registration through the Department of Commerce brings a surety bond with it. Neither is a pesticide rule, and both stop you working just as effectively.
