Private Pesticide Applicator Certification
ATTENTION PRIVATE PESTICIDE APPLICATORS
Do you know your Private Applicator Certification expiration date?

County Extension Offices will no longer send a letter alerting you of when your certification expires.
When is my Expiration Date?
Please check your card to identify when your certification expires. You can self-check your expiration date at: Department of Agriculture, Trade and Consumer Protection’s website. If your name is not listed, then your certification has expired. If you are unable to check online, please contact either the UW PAT Program: 608-262-7588 or Rock County Extension Office at 608-757-5066 for help.
Not sure if you are a Commercial or Private applicator?
