BED BUGS
• HOW MANY OF YOU HAVE SEEN A LIVE BED
BUG?
• HOW MANY OF YOU HAVE EXPERIENCED A
BED BUG INFESTATION?
• HOW MANY USE A CONTRACTOR FOR PEST
MANAGEMENT?
WHY DO WE NEED IPM
• INCREASED RESISTANCE TO
CURRENT INSECTICIDES
• EXPOSURE OF RESIDENTS TO
INSECTICIDES
• SUSTAINABLE SOLUTIONS
BED BUGS ON CAMPUS
• WHERE DO THEY COME FROM?
• WHY ARE THE PROBLEMS SO
SEVERE?
USED FURNITURE
INTERNATIONAL TRAVEL
LOCAL COMMUNITY
WHY ARE THE PROBLEMS SO
SEVERE?
• Important Points.
– Lays 3 to 5 eggs a day
– Total days from egg to
adult is about 30 at 80.6˚ F.
– 5 molts from nymph to
adult
– Can live well over 6 months
without feeding (some
reports over 18 months)
HOW SMALL ARE THEY?
• ADULT IS 3/16 INCH
LONG
• 1ST INSTAR NYMPH
IS ABOUT THE SIZE
OF A PERIOD AT
END OF SENTENCE
• EGGS ARE 1-2 MM
TEMPERATURE EFFECTS
-Below ~55˚ F Development stops
-Above ~99˚ F Development stops
-Thrive at temps between ~68˚ F 80˚ F
-Die at Temps > 113˚F or < 32 ˚F

THE SECURITY THAT THE
BED BUGS ARE DEAD
PRICELESS
ROOM TREATMENT
• VACUUMING
• STEAMING
• APPLYING A RESIDUAL
VACUUM THE CARPET
• THOUROGHLY
VACUUM THE
CARPET AREAS
• CAN BE BEFORE
OR AFTER THE
HEAT TREATMENT
• DISPOSE OF THE
VACUUM BAG
STEAM TREATMENT
• PULL THE CARPET
BACK FROM
BASEBOARDS
• STEAM ALONG ALL
EDGES AT THE
JUNCTION OF
CARPET AND WALL
RESIDUAL APPLICATION
• APPLY RESIDUAL
INSECTICIDE ALONG
JUNCTION OF WALL
AND FLOOR
• APPLY DUST BEHIND
ALL WALL PLATES
WHICH RESIDUALS
• MOSTLY DUSTS WITH SILICA GEL AND
PYRETHRINS
• WHITEMIRE TRI-DIE AND DRIONE ARE
PREFERRED
• DELTA DUST AND BORIC ACID ARE
NOT AS EFFECTIVE
WHOLE ROOM HEAT
• THERE ARE COMPANIES THAT ARE
PERFORMING WHOLE ROOM HEAT
• TWO DIFFERENT ENERGY SOURCES
– PROPANE
– ELECTRICITY
WHOLE ROOM HEAT USING
PROPANE GAS
• WORKS GREAT IF
ALL ROOMS ARE
GROUND FLOOR
• NEED A READY
SOURCE OF
PROPANE
• MAY TAKE UP TO 24
HOURS
WHOLE ROOM HEAT USING
ELECRICITY
• 115 VOLT HEATERS
REQUIRE 6 15 AMP
CIRCUITS TO
OPERATE
• 460 VOLT HEATERS
NEED A
GENERATOR
• GETS RATHER
EXPENSIVE
MANUFACTURERS

ELEMENTS OF IPM
•
•
•
•
•
•
•
•
Education
Communications
Inspection
Identification
Exclusion
Sanitation
Treatment Strategy
Evaluation
EDUCATION
• Institutional staff
• Pest control provider
• Residents
COMMUNICATIONS
• Key element between
participants
• May take a variety of
forms
• Addresses problems,
solutions, and
prevention
INSPECTION
• Performed on an as
needed basis
• Results documented
• Provides early
intervention and
validation of success

IDENTIFICATION
• Sample of pest is
important
• Proper ID is vital
• Leads to proper plans
for control
EXCLUSION
• DIFFICULT TO DO
FOR BED BUGS
• WELL MAINTAINED
FACILITY HELPS
GREATLY
• SIMPLE THINGS
CAN HELP
TREATMENT STRATEGY
• Developed with safety
as important factor
• Utilizing all of IPM
tools
• Can this strategy be
sustained
EVALUATION
• All inspections and
reports documented
• Create a data base
• Analyze data on
regular basis
PREVENTION
• EDUCATE, EDUCATE, EDUCATE
• BEWARE OF USED FURNITURE
• PREPARE SPRING BREAK TRAVEL
ADVISORY
• COULD BE COMMUNITY PROBLEM
PREVENTION TOOLS
• INVERTED SEAM MATTRESSES
• MATTRESS COVERS
• WELL MAINTAINED FACILITY
• WELL EDUCATED RESIDENTS/STAFF
INVERTED SEAM MATTRESS
MATTRESS COVER
MANUFACTURERS
• University Sleep Products –

FACILITY MAINTENANCE
• SEAL UP ALL CRACKS
• SEAL WALL PENETRATIONS
• ELIMINATE ALL HARBORAGES
EDUCATE THE RESIDENTS
• PUBLISH THE DO’S AND DON’TS
• ENCOURAGE THEM TO REPORT EVEN
SUSPECTED BED BUGS
• MAKE IT A PART OF THE
STAFF/RESIDENT ORIENTATION
