1
Goals of Presentation

To introduce MU personnel to integrated
pest management principles

Provide MU personnel with practical tools
and resources to implement IPM in the
work setting
2
What is IPM?
A planned program to prevent
pests & disease vectors from
causing unacceptable damage or
injury to operations, people,
property, or environment.
 An environmentally sensitive
approach to managing pest
problems that takes advantage of
all “suitable” pest management
options

Pesticide use is NOT an option when non-chemical
control methods are available.
3
What does IPM do?

Prevents pest damage to MU facilities and
property

Prevents or minimizes environmental risks

Minimizes pesticide use and avoids
unnecessary pesticide exposure

Minimizes health impact of pests
4
Definition of Pest


An insect, rodent, nematode, fungus, weed,
terrestrial or aquatic plant, animal life, virus,
bacteria, or other organism designated by rule
as a pest.
Does not include a virus, bacteria or other
microorganism (on or in) living humans or other
animals.
As defined in (State Statute)
5
IPM Goal
To develop (specific tailored) pest management strategies to
minimize potential adverse impacts on human health and to
protect the environment
Methodology
ID infestations

Steps to a Successful IPM Program


Understand the Problem/Requirement &
Educate the Customer *
Analyze the Pest Problem – Establish threshold
Take Short-Term, Corrective Action
Implement Long-Term, Preventive Action
Monitor, Document,
Pest problems are not all
& Evaluate Results
alike.
Situational pest
Customer* Feedback
* Residents, Guests, Faculty & Staff
management requires
understanding specific pest
habits & preferences.
7
MU PLAN OF ATTACK

Establish an IPM policy and
implementation plan

Develop initial staff IPM training

Ensure daily, weekly, and monthly
inspections are taking place
8
Staff Responsibilities/Support


Maintain good sanitation & housekeeping
standards to prevent pest access & harborage
Leave pest control and pest management to
trained professionals





Do not use pesticides or call in pesticide applicators
Do not move sticky traps or other pest
monitoring products
Do not prop open windows or screens
Remove trash, especially food routinely
Keep areas dry

Clean up standing water or wet items
Suggestions from Department of Agriculture

MU Managers



Train MU Staff
Appoint personnel to conduct inspections and maintain Pest
Sighting Log
Ensure Building Inspections are conducted per required
schedule
Maintain Pest Sighting Log; accessible to the MU Staff
Follow-up on recommendations from IPM staff
Post/Disseminate “Notice of Pesticide Application”
Monitor problematic areas:






Trash & Garbage Areas
Dish Rooms
Food Storage Areas
Basements
Loading Docks
Under and behind appliances – move as needed to inspect
10
A Successful Pest Needs
 Food
 Water
 Shelter
Reduce pesticide use by reducing pest populations.
11
Action Thresholds/Triggers
Modify habitats—to make areas less hospitable,
remove or reduce food and water and/or shelter

Use non-chemical tactics when possible
Structural (exclusion); Physical (sanitation)
Mechanical (vacuum); Cultural (fertilizing)- weed species

Identify specific acceptable levels of pest activity
If pest population is too high or hazardous, chemical control
may be needed
 Use least toxic product possible
 Follow label directions –IT IS THE LAW
 Keep records to track successes and problems
12
Premises Pest Exclusion


Eliminate Harborage Conditions:
 remove cardboard boxes & recyclable material
Eliminate Structural Defects:
 caulk holes & cracks in walls and around door
frames
Repair/Replace Torn or Missing Window Screens:
 screens are > 16-mesh per inch
Keep storage areas, break rooms and loading
docks clean
Organize kitchens to maximize access and
minimize harborage
13
Stock Handling Practices
-- Applying Pest Management -Infested Foods & Supplies:


Inspect incoming shipments
received.
Rotate stock:



reduces potential of old
product infestations
reduces spread of pests
from infested products
Remove unnecessary
materials (harborage),
particularly in storage areas

4 steps of IPM
Inspect

Step 1: The Inspection
•Extendable mirror
•Flashlight
4 essential
inspection
tools
•Inspection form and
clipboard
•Digital camera
16
Routinely, look for



Evidence of pests
Unsanitary conditions
Correctable Conditions






Leaky pipes
Unsealed cracks
Spilled food
Gaps under exterior doors
Harborage (cardboard boxes)
Others ?
17
Step 2: Identification

Need to know the specific pest/problem
in order to determine the appropriate
control method(s).

If you kill it, bag it for identification by
trained personnel if you’re not sure
what it is.
18
Step 3: Taking Action
Wham!

IPM Management Methods
Short versus long term results
 Must change habitat for long term
solution



Eliminate food, water and/or shelter
Correct structural problems that permit
pest entrance.
Screens
 Caulking
 Utility penetrations
 Foundation cracks

When pesticide treatments become necessary

Evaluate products for effectiveness
and toxicity

use methods that minimize unnecessary
pesticide exposures, where possible
Provide notification or posting, as
required by label or law
 Allow only properly trained
individuals to apply the (appropriate)
product.

Dig burrows around foundation

Attracted to debris & unsecured food (waste)

Problems originate
outside of building
Mice

1/2-inch gaps; Mice only
need ¼ inch

Can enter building from outside; problems
originate indoors

Nest w/in 15 feet of food source

Spread through a structure along pipes,
cables, & ducts

Raised flooring & Lowered ceilings provide
harborage

What we do after Catching a Rat

Don PPE (gloves)


In some cases, it
might be better to
use a “Grabber”
instead of hands
though.
We don’t reuse
wood-traps, toss
animal and trap in
trash bag together
34
Killed Rodents Go Where?

After depositing the
rodent in the
trashbag, soak him
in pre-mixed Hepistat
256

Tie knot in end of
bag and toss entire
package into
dumpster/compactor
35
Cleanup After the Kill

Spray the spot the rodent was trapped
with Hepistat 256 and wipe dry AFTER 10
minute dwell

Spray all tools/implements.

Clean and reload trap (if re-usable).

Toss out gloves
