Maybe they’d take me seriously if I put some pants on…
3
Schools, child care centers, homes, hospitals, retirement / nursing facilities, restaurants, hotels
Challenging places for pest management
Host diverse people, confined spaces, different lengths of time
Schools – Sensitive Environments 4
Have health problems such as asthma, allergies, or immune system compromising diseases
Include diverse physical spaces, indoors and out, that provide ideal entry points and harborages for pests, and require customized solutions to pest problems
Diminishing budgets and deferred maintenance worsen these problems
5
What is a pest?
• Organisms that are detrimental to humans or their interests• Damage crops and structures• Impact human or animal health• Reduce aesthetic and recreational
value• Organisms that are out of place!
6
• A pest can be a:• Plant (weed)• Vertebrate (bird, rodent, or other mammals)• Invertebrate (insect, tick, mite, or snail)• Nematode• Pathogen (bacteria, virus, or fungus)• Other unwanted organism
7
Why are there pests?
• Biological entities• Seek food, shelter, and water!

Why should we care about pest management?10
Bite / sting Damage food by entering and feeding Contaminate food and surfaces A nuisance when they invade buildings Cause allergies, asthma and other reactions Vector disease microbes Cause structural damage Cause plant damage
Pests!!!
11
Actions!!!
Why should we care about pest management?
12
Bills!!! Pests cost money! Repeated pesticide applications Unsafe pesticide exposure can result
in costly litigation Unchecked pest infestations
Why should we care about pest management?
There is a solution!13
IPM = Integrated (Intelligent) Pest Management!A sensible, environmentally friendly, and effective
way to solve pest problems
IPM is a team effort!
The IPM Approach
• IPM is sustainable approach to managing pests by combining biological, physical, and chemical methods in order to minimize economic, health and environmental risks
• IPM can be used to manage all kinds of pests anywhere – in urban, agriculture, wildland or natural areas

The IPM Approach
16
IPM focuses on correcting the fundamental reasons why pests are present
What are they?
When do they show up?
Where are they occurring?
How did they arrive or get in?
Why are they here?
The IPM Approach
• IPM is proactive – monitoring and inspecting is constant
• Promotes environmental health• Works indoors and outdoors• Pesticides are used only when
necessary

Key Elements of IPM - Identification
Pest identification and location: What is it? Where is it? How did it get there? Why is it there? When is it showing up?
22
4.
Key Elements of IPM - Identification
Pest identification is critical! Use good resources
Take the help of specialists
Handle samples carefully

Key Elements of IPM – Inspection and Monitoring
To detect pest problems as early as possible To address pest
conducive conditions before problems occur, especially in pest vulnerable areas (PVA’s) like kitchens,and food serviceareas

28
What to look for: 1. Pests2. Signs of pests3. Pest conducive conditions -
pest opportunities inviting pests for food, water, and harborage
Inspection and Monitoring
Mouse poop on a spoon
The best way to know if or when pests are present is by regular inspection and monitoring
Cockroaches feeding on crumbs
29
Where to look:1. Dark shadowy corners2. Hard to reach areas3. Undisturbed places/ under
and behind stationary items4. Warm and/or wet places5. Food storage and/or preparation areas6. Waste collection containers and areas7. Dropped ceilings
Inspection and Monitoring
Tiles in drop ceiling indicating roof or plumbing leak
30
Where to look:8. Warm walls with penetrations9. Compressor motor voids in equipment10. Unsealed floors and
floor to wall junctures11. Undisturbed containers12. Cardboard boxes13. Clutter
Inspection and Monitoring

31
Tools:1. Monitoring traps2. Bright flashlight3. Hand lens
Inspection and Monitoring
Inspection also involves the regular observation and recording of: The physical condition of buildings and grounds Detection of DIY pest control
attempts

32
Inspection and Monitoring
7.
Water is a critically important pest resource Monitor and repair leaks Repair leaky valve boxes Keep flooring and surfaces dry Ensure rainwater drains away from buildings Ensure air-conditioning
condensate does not pool in drop ceiling tiles or attics
33
Key Elements of IPM – Pest-conducive Conditions
34
Exposure to mold can cause health problems for sensitive individuals
Exposure may cause or worsen conditions such as asthma, hay fever or allergy symptoms
Key Elements of IPM – Pest-conducive Conditions
35
Key Elements of IPM – Pest-conducive Conditions
Shrubs should be pruned away from buildings and shaped so they do not create places for rodents to hide
Keep tree limbs pruned at least six feet away from buildings
Remove vines climbing on buildings or growinglow to the ground next to buildings
36
Key Elements of IPM –Pest-conducive Conditions
De-clutter!
37
Key Elements of IPM –Pest-conducive Conditions
Eliminate access to food
4.
Key Elements of IPM – Inspect, Monitor, Measure
Regular monitoring is the most economical and simple strategy to manage pests
Using ongoing monitoring tools allows for constant assessment of pest activity when you can not be around
Monitoring helps determine pest population levels and how the pests are accessing or beingintroduced into buildings
38
39
Key Elements of IPM – Inspect, Monitor, Measure
Traps catch 24-7 and help you identify the pest, determine how many there are, assess the direction of travel and determine harborage locations
3.
40
Use pest-sighting logs These are a convenient
and efficient way to record and report
Encourage and reward school personnel for reporting pests
Key Elements of IPM - Reporting
Key Elements of IPM - Reporting41
Systems allow methodical data tracing which may be legally required
Report:Pests foundSigns of pestsSupportive conducive conditionsPest entrywaysUnsanctioned pest control attempts
Recordkeeping is important because it allows: Accurate flow of information
from one employee to another Pest management to identify
trends in pest populations Documentation of problems
and evaluation of solutions Legal compliance

Key Elements of IPM – Sanitation and Waste Management
43
Waste management = Pest management!
7.
Key Elements of IPM – Sanitation and Waste Management
44
Maintain garbage chute systems and dumpsters clean and keep dumpster and surrounding areas free of debris
7.
Key Elements of IPM – Sanitation and Waste Management
45
Place dumpsters on a concrete or asphalt surface 30-50 feet away from building entryways
7.
Key Elements of IPM – Sanitation and Waste Management
46
Sanitation Clean up after group activities,
especially those involving food and drinks
Anything with food remains should be placed in trash cans, bagged, and taken to outside dumpsters before the day ends
7.
Key Elements of IPM – Sanitation and Waste Management
47
Sanitation Common room furniture should be checked and
cleaned periodically
Upholstered furniture is difficult to keep clean,
especially where food is consumed including
teachers lounges, and coaches, maintenance or custodial offices – Dawn H. Gouge, University of
Arizona
48
Pest-proofing includes preventing pests from the outside getting in, and preventing hitchhiking pests brought in by building occupants and in deliveries from spreading
Seal cracks, crevices and holes around exterior wall penetrations
Key Elements of IPM – Maintenance and Pest-proofing
49
Seal your buildings, make sure doors seal and self-close correctly
The vertical gap in the doorway (right) should be closed with brushes
Exterior doors should never be left propped open. Mice can enter through a ¼” gap. Effective door sweeps can cut pest complaints by 65%!
Prevent pest entry
Key Elements of IPM – Maintenance and Pest-proofing
Understand pest mode of feeding/habitat for effective reach
Treat only when populations reach action thresholds Time treatments to be least disruptive to beneficials Avoid broad-spectrum insecticides, toxic to many species
of insects Select targeted, low-risk pesticides, such as Bacillus
thuringiensis, insect growth regulators, and baits formulated to attract only the target pest
Read the label – the label is the LAW!
Pesticides
Use pesticides only when necessary & be selective when you choose a product
Use least hazardous options first Attempt to preserve natural
enemies Select least toxic materials Use broad-spectrum
insecticides as an absolute last resort
When using pesticides…
Pesticides are important tools. They should be used effectively and safely

Key Elements of IPM – Education and Communication
54
Form partnerships with surrounding groups: Your pest management professional Non-governmental organizations working to improve
environmental health and safety University Extension Your department of health
and State Lead Agency responsible for regulating pesticides
15.
55
Outreach events in schools Non-conventional education
Key Elements of IPM – Education and Communication
Key Elements of IPM - Evaluation
Your IPM program should be evaluated annually to determine what is working and what is not?
Are pests persisting? Are there any emerging issues? Are pest management methods and products the
least hazardous and effective? Are there community
communication challenges or education needs?
15.
56
Rules, Regulations and Policy15.
57
Notifications
Common Problems
No monitoring in PVAs No PMP hours with staff Excess pesticide use e.g. 143 applications for 3 schools
in one year No ID e.g. “red ants” or “sugar ants” Poor knowledge e.g. mice have no bones No communication with or education of faculty and
staff OTC pesticides Poor partnerships IPM costs more….
IPM must be compatible with current operations
Doing what you do now---just think pests!!!• Security = monitoring• Energy conservation = exclusion• Sanitation = nothing to eat• Clutter control = no place to live
Food Water Shelter
Have a policy for each pest
• Response plan• Thresholds• Management
protocols• Communication
protocols
Prepare Your School IPM Plan https://extension.arizona.edu/sites/extension.arizona.edu/files/pubs/az1669-2015.pdf
When transitioning from a traditional monthly treatment service to an IPM program, costs usually decreasedin the long-term
IPM is the best way to manage pests in your environment!
