B. Monitoring – Reporting – Action Protocol
1. Three levels of monitoring
There are three levels of monitoring:
1) Casual observing/looking with no record keeping is not helpful.
2) Casual observing/looking with some documentation can be useful.
3) Careful inspection with proper documentation by the custodial foreman is always useful.
Level 2 monitoring (all staff):
All staff will be trained to improve their “casual observing/looking” to level 2, and to report any pests and pest conducive conditions they observe to the Custodial Foreman who will document the problems. Level 2 monitoring is conducted by faculty, administrators, maintenance/construction, kitchen staff, school nurse, etc.
Staff will be expected to report pests or pest conducive conditions they observe during the normal course of their daily work. Pest problems will be reported to the Custodial Foreman who will take action and document the incidents in the pest log. Custodial and kitchen staff are expected to set and/or check sticky monitoring traps as per the district’s IPM plan.
Level 3 monitoring (IPM Plan Coordinator and Custodial Foremen).
The IPM Plan Coordinator (or designee) and the custodial foreman will periodically conduct monitoring at level 3. The IPM Coordinator and Custodial Foreman will inspect buildings for:
• Unsanctioned pesticide use by teachers and school staff and report use to the IPM Coordinator.
• The level of sanitation inside and out (waste disposal procedures, level of cleanliness inside and out, conditions that supply food and water to pests).
• The amount of pest damage and the number and location of pest signs (rodent droppings, termite shelter tubes, cockroaches caught in sticky traps, etc.).
• Human behaviors that affect the pests (working conditions that make it impossible to close doors or screens, food preparation procedures that provide food for pests, etc.).
• The results of their own management activities (caulking/sealing, cleaning, setting out traps, treating pests, etc.) and their effects on the pest population.
Level 3 monitoring (Grounds staff)
Grounds staff will monitor Turf and Landscape for:
• Unsanctioned herbicide use by coaches, volunteers, and others. Report any unsanctioned pesticide use to the IPM Coordinator.
• The results of their own management activities (pruning, fertilizing, mulching, aeration, treating pests, etc.) and their effects on the plants and the pest population.
2. Sticky monitoring traps for insects
Sticky traps are neither a substitute for pesticides nor an alternative for reducing pest populations, but rather a diagnostic tool to aid in identifying a pest’s presence, their reproductive stage, the likely entry points of pests, and the number of pests.
All staff will be made aware of the traps and their purpose so they don’t disturb them. Custodial Foreman will be responsible for setting them out and checking them once per month and replacing them once every four months Kitchen staff will be responsible for checking those in the kitchen primarily for cockroaches and drain flies once per week.
After receiving training from the IPM Plan Coordinator (or designee) in the use of pest monitoring sticky traps, Custodial Foreman will be responsible for checking traps placed in pre-determined “pest-vulnerable areas”. These areas include the staff room and kitchen (and any other areas determined by the Custodial Foreman or IPM Plan Coordinator). If the Custodial Foreman cannot interpret what they find in the monitors they will contact the IPM Plan Coordinator for assistance.
3. Reporting (pests, signs of pests, and conducive conditions)
When the staff observes pests or pest conducive conditions they should report them to the Custodial Foreman for him/her to write them down and follow protocol under #5 Action below.
4. Reporting “Pests of Concern”
“A pest of concern” is a pest determined to be a public health risk or a significant nuisance pest. These include cockroaches (disease vectors, asthma triggers), mice & rats (disease vectors, asthma triggers), yellow jackets (sting can cause anaphylactic shock), cornered nutria, raccoons, cats, dogs, opossums, skunks (they can bite), and bed bugs (significant nuisance pest).
When pests of concern (or their droppings, nests, etc.) are observed, staff should immediately tell the custodial foreman. The Custodial Foreman must contact the maintenance office immediately. The maintenance office will then contact the IPM Plan Coordinator.
5. Action!
a) Structural
Any items (such as sealing up holes) that maintenance/construction staff or custodial staff observes that they can resolve in a short amount of time should be taken care of and the action should be noted in the pest log by the Custodial Foreman.
Pest Logs will be faxed or scanned/emailed to the IPM Plan Coordinator once per month if there are items noted on the log. If nothing is noted in the log, the IPM Coordinator will determine further actions to be taken and when.
If the actions needed are not something the Custodial Foreman can accomplish alone or with minimal assistance, the Custodial Foreman will work with the District Field Supervisor to develop a protocol and priority list with deadlines for sealing holes, installing external door sweeps, and other pest exclusion or pest management needs. The custodial foreman will then generate a work order with a proposed deadline for completion based on the severity of the risk or nuisance.
The IPM Coordinator will monitor the completion of the IPM Work Orders by working with the District Field Supervisors. Upon completion of the work, the IPM Coordinator and the school Custodial Foreman will be notified.
The IPM Coordinator will keep records of time and money spent to manage the pest, and quantities of chemicals used.
Ants:
When Custodians observe a small number of ants they must:
- Spend the time needed trying to find out where the ants are coming from.
- Kill the ants with a paper towel or vacuum up.
- Remove any food or liquid the ants were eating.
- Wipe down the area with soapy water or disinfectant to remove the pheromone trails.
- Document actions in the pest log.
If the ants come back or there are more than a small number of them:
The Custodian will:
- Assess the entry point of the ants.
- Vacuum up the ants and any food debris nearby (dispose of the vacuum bag after vacuuming up ants).
- Seal up the cracks or holes where the ants are entering the building or submit a work order.
- Wipe down the area with soapy water or disinfectant to remove pheromone trails.
- Document the above actions in the pest log.
- Contact the Custodial Supervisor.
To avoid a proliferation of small ants and/or unnecessary pesticide applications, the routine use of ant baits is not permitted without first:
- Educating the staff on proper sanitation, monitoring and exclusion as the primary means to control ants in the buildings.
- Establish an acceptable pest population density (e.g. 10 or more ants).
- Improve sanitation (cleaning up crumbs and other food sources) and structural remediation (sealing up cracks and holes that provide entry points for ants.
b) Grounds
When pests on grounds reach a threshold established by the Grounds Foreman/lead and the IPM Plan Coordinator, action will be taken as provided by the IPM Plan Coordinator.
6. Acceptable Thresholds (pest population density levels)
A threshold is the number of pests that can be tolerated before taking action. The acceptable threshold for cockroaches, drain flies, ants, silverfish, mice, rats, raccoons, cats, dogs, opossums, skunks, and nutria is zero.
Acceptable thresholds for safety concerns of other pests will be determined by the IPM Plan Coordinator and the Maintenance Department.
C. Inspections
1. Routine Inspections:
The IPM Plan Coordinator will conduct routine inspections of different schools throughout the year (schedule and schools to be determined by the Coordinator). Site Custodial Foreman will accompany the IPM Coordinator during the inspections as needed. The inspections will focus on compliance with the IPM Plan and an inspection of the kitchen, staff room, and any other place of concern. After each routine inspection the IPM Coordinator will write a one-page report on findings and recommendations. The report will be submitted to the school Principal and Custodial Foreman.
2. Annual Inspections:
The IPM Plan Coordinator will conduct annual inspections at individual schools. Site custodians will assist the IPM Coordinator with the annual inspection. The annual inspections will be more thorough than the routine inspections, and will use the Annual IPM Inspection Form to guide the inspections. The specific school or schools to be inspected will be determined by the IPM Plan Coordinator based on a review of the annual number of pest problems and pesticide applications reported in the Annual IPM Report and Annual Report of Pesticide Applications.
D. Pest Emergencies/Safety Concerns (see also Section V. B. below)
IMPORTANT: If a pest emergency is declared that is a safety concern, the area must be evacuated and cordoned off before taking any other steps. When the IPM Plan Coordinator, after consultation with school faculty and administration, determines that the presence of a pest or pests immediately threatens the health or safety of students, staff, faculty members or members of the public using the campus, or the structural integrity of campus facilities, he or she shall declare a pest emergency. Examples include (but are not limited to) yellow jackets swarming in areas frequented by children, a nutria in an area frequented by children, a half a dozen mice or rats running through occupied areas of a school building.
E. Annual IPM Report (completed by IPM Plan Coordinator)
In January of each year, the IPM Plan Coordinator will prepare an annual IPM report. The report will include a summary of data gathered from Pest Logs, as well as costs for contracted pesticide services and pesticides (including turf and landscape pesticides). Costs for items such as sealants, fixing screens, door sweeps and other items that would not normally be considered part of pest control will not be recorded.
Prevention and management steps taken that proved to be ineffective and led to the decision to make a pesticide application will be included in the annual report of pesticide applications (see section V. D)
Required Training/Education
IV. REQUIRED TRAINING/EDUCATION
ORS 634.700 (3) (i) requires staff education “about sanitation, monitoring and inspection and about pest control measures”.
A. IPM Plan Coordinator Training
ORS 634.720 (2) requires that the IPM Plan Coordinator “shall complete not less than six hours of training each year. The training shall include at least a general review of IPM principles and the requirements of ORS 634.700 to 634.750.”
Content should include health and economic issues associated with pests in schools, exclusion practices, pest identification and biology for common pests, common challenges with monitoring-reporting-action protocols, proper use of sticky monitoring traps for insects, and hands-on training on proper inspection techniques.
B. Training for Custodial Staff

C. Training for Maintenance and Construction Staff
The IPM Plan Coordinator (or a designee of the Coordinator) will train maintenance staff on identifying pest conducive conditions and mechanical control methods (such as door sweeps on external doors and sealing holes under sinks), and their responsibilities as outlined in Section V. A.
D. Training for Grounds Staff
The Grounds Foreman will train grounds staff. Prior to training, the Grounds Foreman will meet with the IPM Plan Coordinator to review the annual report of pesticide applications and plan training for all grounds staff. The training will review this IPM Plan (especially grounds department responsibilities outlined in Section V.A.) and data from the annual report related to pesticide applications by grounds crew.
E. Training for Nutrition Services Staff
The IPM Plan Coordinator (or a designee of the Coordinator) will train kitchen staff on the basic principles of IPM and their responsibilities as outlined in Section V. A.
F. Training for Faculty and Principal

G. Other Training
Basic training on the principles of IPM and the main points of this IPM Plan will also be made available to school nurses, administrative staff, superintendents, coaches, and students.
Pesticide Applications: Required Notification, Postings, Record Keeping, and Reporting
V. PESTICIDE APPLICATIONS: REQUIRED NOTIFICATION, POSTING, RECORD
KEEPING, AND REPORTING
Any pesticide application (this includes weed control products, ant baits, and all professional and over-the-counter products) on school property must be made by a licensed commercial or public pesticide applicator. Each school year, all faculty, administrators, staff, adult students and parents will be given a list of potential pesticide products that could be used in the event that other pest management measures are ineffective. They will also be informed of the procedures for notification and posting of individual applications, including those for pest emergencies. This information will be provided on the district’s website, on the individual school’s website, and posting in the main office at the school.
A. Notification and Posting for Non-emergencies
When prevention or management of pests through other measures proves to be ineffective, the use of a low-risk pesticide is permissible. Documentation of these measures is a pre-requisite to the approval of any application of a low-risk pesticide. This documentation will remain on file with the IPM Plan Coordinator.
If the labeling of a pesticide product specifies a reentry time, a pesticide may not be applied to an area of campus where the school expects students to be present before expiration of that reentry time. If the labeling does not specify a reentry time, a pesticide may not be applied to an area of a campus where the school expects students to be present before expiration of a reentry time that the IPM Plan Coordinator determines to be appropriate based on the times at which students would normally be expected to be in the area, area ventilation and whether the area will be cleaned before students are present.
The IPM Plan Coordinator (or a designee of the Coordinator) will give written notice of a proposed pesticide application (on the district’s website, on the individual school’s website, and posting in the Main Office at the school) at least 24 hours before the application occurs.
The notice must identify the name, trademark or type of pesticide product, the EPA registration number of the product, the expected area of the application, the expected date of application and the reason for the application.
The IPM Plan Coordinator (or a designee of the Coordinator) shall place warning signs around pesticide application areas beginning no later than 24 hours before the application occurs and ending no earlier than 72 hours after the application occurs.
A warning sign must bear the words “Warning: pesticide-treated area”, and give the expected or actual date and time for the application, the expected or actual reentry time, and provide the telephone number of a contact person (the person who is to make the application and/or the IPM Plan Coordinator).
B. Notification and Posting for Emergencies
Important Notes:
- The IPM Plan Coordinator may not declare the existence of a pest emergency until after consultation with school faculty and administration.
- If a pesticide is applied at a campus due to a pest emergency, the Plan Coordinator shall review the IPM plan to determine whether modification of the plan might prevent future pest emergencies
The declaration of the existence of a pest emergency is the only time a non-low impact pesticide may be applied.
If a pest emergency is declared, the area must be evacuated and cordoned off before taking any other steps.
If a pest emergency makes it impracticable to give a pesticide application notice no later than 24 hours before the pesticide application occurs, the IPM Plan Coordinator shall send the notice no later than 24 hours after the application occurs.
The IPM Plan Coordinator or designee shall place notification signs around the area as soon as practicable but no later than at the time the application occurs.
Note: ORS 634.700 also allows the application of a non-low-impact pesticide “by, or at the direction or order of, a public health official”. If this occurs, every effort must be made to comply with notification and posting requirements above.
C. Record Keeping of Pesticide Applications
The IPM Plan Coordinator or designee shall keep a copy of the following pesticide product information on file at the school’s main office where the application occurred, the Central Office Risk Management Department, and at the office of the Coordinator:
- A copy of the label
- A copy of the MSDS
- The brand name and USEPA registration number of the product
- The approximate amount and concentration of product applied
- The location of the application
- The pest condition that prompted the application
- The type of application and whether the application proved effective
- The pesticide applicator’s license numbers and pesticide trainee or certificate numbers of the person applying the pesticide
- The name(s) of the person(s) applying the pesticide
- The dates on which notices of the application were given
- The dates and times for the placement and removal of warning signs
- Copies of all required notices given, including the dates the IPM Plan Coordinator gave the notices
The above records must be kept on file at the school’s main office where the application occurred, and at the office of the IPM Coordinator, for at least four years following the application date.
D. Annual Report of Pesticide Applications
In January of each year, the IPM Plan Coordinator will prepare an annual report of all pesticide applications made the previous year. The report will contain the following for each application:
- The brand name and USEPA registration number of the product applied
- The approximate amount and concentration of product applied• The location of the application
- The prevention or management steps taken that proved to be ineffective and led to the decision to make a pesticide application
- The type of application and whether the application proved effective
Approved List of Low-Impact Pesticides
VI. APPROVED LIST OF LOW-IMPACT PESTICIDES
Note: All pesticides used must be used in strict accordance with label instructions.
According to ORS 634.705 (5), the governing body of a school district shall adopt a list of low-impact pesticides for use with their integrated pest management plan. The governing body may include any product on the list except products that:
a) Contain a pesticide product or active ingredient that has the signal words “warning” or “danger” on the label;
b) Contain a pesticide product classified as a human carcinogen or probable human carcinogen under the United States Environmental Protection Agency 1986 Guidelines for Carcinogen Risk Assessment; or
c) Contain a pesticide product classified as carcinogenic to humans or likely to be carcinogenic to humans under the United States Environmental Protection Agency 2003 Draft Final Guidelines for Carcinogen Risk Assessment.
As a part of pesticide registration under the Federal Insecticide Fungicide and Rodenticide Act (FIFRA) and re-registration required by the Food Quality Protection Act (FQPA), EPA Office of Pesticide Programs (OPP) classifies pesticide active ingredients (a.i.) with regards to their potential to cause cancer in humans. Depending on when a pesticide active ingredient was last evaluated the classification system used may differ as described above.
