Your pesticide applicator’s certificate: how long it lasts

Federal rules say a commercial or private certification expires five years after it’s issued unless you recertify, and a state can set a shorter period. So your pesticide applicator’s certificate lasts as long as your state says, from one to five years in the states in this guide. You renew it before it expires, by passing an exam again or with approved continuing education.

Certificate or license?

Several states keep the two apart. The certificate shows you passed; the license lets you work, and in some states it’s renewed every year. Wisconsin’s certification lasts five years but its commercial license runs each calendar year. Indiana, Oregon and North Carolina also pair a five-year certification with a yearly license. In Oklahoma, the Department of Agriculture, Food and Forestry (ODAFF) says the certification card isn’t a license to do pesticide work at all.

For commercial work, a yearly license may sit on top of these. Each state page has the credits, dates and fees.

Recertifying by exam or by credits

Under the Code of Federal Regulations (CFR) at 40 CFR 171.107 you can recertify by passing a written exam that meets the same standards as the first one, or by finishing a continuing education program in your state’s approved plan. The state has to approve each course and check that you completed it, online courses included. Some states offer only one route for some categories: Iowa renews four of its categories by exam only, and the University of Wisconsin Pesticide Applicator Training (UW PAT) Program says Wisconsin private applicators recertify the same way they certified the first time.

If your certificate has lapsed

Your state decides how long you have. Pennsylvania gives you up to a year to reinstate, Florida lets you renew up to a year after expiry, and New York won’t let you recertify after two years expired. After that, you take the exams again.
