4.3 Ohio's Integrated Pest Management Standard (OAC 901:5-11-14)
Key Takeaways
- OAC 901:5-11-14 applies to anyone developing and implementing IPM activities for non-agricultural uses in Ohio, including pesticide businesses and school personnel.
- An activity only counts as IPM under Ohio rule if it contains all four required elements - assessment, joint determination, monitoring strategy, and evaluation.
- The site assessment must identify structural, mechanical, storage, or sanitation conditions producing pest problems, entry points and harborage, the type and extent of pest activity, and potential impacts.
- Decisions about whether chemical control is necessary must be made with the entity contracting for service, not unilaterally by the applicator.
- Evaluation requires re-assessing the site on an agreed timeframe and asking whether corrections were made, whether methods worked, and whether exposure risks were sufficiently minimized.
4.3 Ohio's Integrated Pest Management Standard (OAC 901:5-11-14)
Most states teach IPM as a philosophy. Ohio wrote it into rule. OAC 901:5-11-14 defines the minimum content of an "IPM activity" for non-agricultural uses in Ohio, and it binds pesticide businesses, school personnel, and anyone else conducting IPM activities. If a contract, bid, or marketing claim uses the words "integrated pest management," this rule is the yardstick.
The rule is short and entirely procedural: in order to be considered an IPM activity, the activity shall include all the elements in paragraph (B). Four elements, in order.
Element 1: Comprehensive Site Assessment
Conduct a comprehensive assessment of the property for which the IPM activity is being developed. The assessment must identify:
- (a) Structural, mechanical, storage, or sanitation conditions that are producing or could produce pest problems, including pest entry points and areas prone to pest harborage
- (b) The type and extent of pest activity, which may be determined using monitoring devices when practical
- (c) Potential impacts presented by the pests to humans, domestic animals, and the environment
The assessment looks for the conditions that cause the problem, not merely the pests present. A dumpster too close to a loading door, a dripping condensate line, a gap under a dock plate, and unrotated dry goods are all findings a compliant Ohio assessment records.
Element 2: Determinations Made With the Contracting Entity
Determine with the entity contracting for service:
- (a) Structural, mechanical, storage, or sanitation-related measures that will aid in long-term prevention, elimination, or control
- (b) Priorities for pest control and elimination
- (c) Whether chemical control is necessary to prevent, eliminate, or control pests
- (d) The most effective measures, application products, and methods that will control pests while minimizing exposure to humans, domestic animals, and the environment
The phrase "determine with" is the operative language. Under Ohio's rule, the decision to use a pesticide in an IPM program is a joint decision with the customer, documented, not a unilateral technician call. This is the element most often missing when ODA reviews a program that advertises IPM.
Element 3: An Agreed Monitoring Strategy and Schedule
Establish with the entity contracting for service a strategy, schedule, and specific recommendations for ongoing site monitoring and assessment to resolve short-term and long-term control or elimination of pest problems.
In practice, this becomes the service agreement's inspection interval, the monitoring-device map, the thresholds that trigger action, and the written recommendations the customer is expected to implement.
Element 4: Evaluation and Re-Assessment
Evaluate the results of implementing the IPM activity within a timeframe agreed with the contracting entity. The evaluation must include a re-assessment of the site and must consider whether:
- (a) Correction of structural, mechanical, storage, or sanitation problems was completed and effective
- (b) Methods used to prevent, control, and eliminate pests at the site were effective
- (c) Risks of exposure to humans, domestic animals, and the environment were sufficiently minimized
- (d) Other measures, products, or methods should be chosen for future pest management
The Ohio IPM Cycle at a Glance
| Step | Required content | Documentation that proves it |
|---|---|---|
| 1. Assess | Conditions producing pests, entry points, harborage, type and extent of activity, potential impacts | Written initial inspection report with a device map |
| 2. Determine with the customer | Corrective measures, priorities, whether chemicals are needed, least-exposure methods | Signed service specification or scope of work |
| 3. Monitor | Strategy, schedule, specific recommendations | Service agreement interval plus monitoring log |
| 4. Evaluate | Re-assessment against four listed questions | Periodic program review report |
Why This Matters on the Exam and on the Job
- ODA's Core exam content description names integrated pest management explicitly among the areas assessed.
- The schools rule effectively presumes an IPM approach, because the products allowed while school is in session are baits, stations, and void treatments - exactly the toolset an assessment-driven program produces.
- Claiming "IPM" in a bid without performing the four elements risks ORC 921.24(E), falsely or fraudulently representing the effect of pesticides or methods to be utilized.
- The rule's authority is ORC 921.18 and it amplifies ORC 921.01 and 921.18 - it is enforceable, not advisory.
The general IPM concepts taught in the national core manual - identification, monitoring, thresholds, and the cultural, mechanical, biological, regulatory, and chemical tactic families - remain the substance of what you do. Ohio's rule simply fixes the process you must follow when you call that work IPM.
