The Oklahoma Department of Agriculture is the lead state agency for regulating pesticides.  This responsibility includes investigating complaints of alleged pesticide / herbicide misuse.  Typical complaints concern termite treatments, drift from lawns, right-of-way or agricultural applications.

How to File a Complaint

Anyone wishing to file a complaint needs to complete the PESTICIDE COMPLAINT STATEMENT and submit it to Mike Vandeventer by mail, fax or email.  Once the complaint is received it will be given a complaint number and assigned to a field inspector.  You will receive confirmation that the complaint was received with the name of the inspector and the complaint number.

The Investigation

The inspector will contact you within the next three to four days to schedule the inspection.  The inspection will include a narrative report, photos and samples as needed to document a misuse or violation.  The inspector does not estimate monetary losses that may have occurred as a result of the incident.  He will also try to identify any possible source or cause.

All possible sources will be contacted to determine if they were involved or not.  Once the investigation is completed by the Compliance Administrator you will be notified of the final action taken.

Copies of the Report

The investigation report is subject to the Oklahoma Open Records Act.  A copy of the report will be provided upon written request.  Requests should reference the complaint number and be sent to:
