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?
• A partnership of the Public Policy Research Center at the University of
Missouri-St. Louis and the St. Louis Lead Prevention Coalition.
• A 12-month project
• Funded by a grant from the EPA
Special Thanks to the following for their assistance, their expertise, and permission to use materials

TEMPERATURE EFFECTS-Below ~55˚ Development stops
-Above ~99˚ Development stops
-Thrive at temps between ~68˚ F - 80˚ F
-Die at Temps > 113˚F or < 32 ˚F
Adults
Temperature affects life-span At 98°, females live an
average of 32 days while males live an average of 29 days
At 50°, females live an average of 425 days while males live an average of 401 days
Females can lay between 200 and 500 eggs in their lifetime
(Johnson 1942, Usinger 1966)
½ of the blood ingested is lost by defecation within 5 hours.
Can be confused with… Ticks Cockroach nymphs Bat bugs Carpet beetles Other kinds of bug bites

FOCUS ON INSPECTIONS
INSPECTIONS ARE AS CHALLENGING AS TREATMENTS
PROPER INSPECTIONS REQUIRE TIME
INSPECTIONS CAN BE PHYSICALLY CHALLENGING
TWO TYPES OF INSPECTIONS
INITIAL INSPECTION
POST TREATMENT INSPECTION
INITIAL INSPECTION
SEARCHING FOR ANY INDICATION OF INFESTATION
LIVE INSECTS CAST SKINS BLOOD SPOTS
POST TREATMENTINSPECTION MORE DIFFICULT INSPECTION
MUST LOOK FOR LIVE INSECTS AND EGGS
MUST SEARCH FURTHER AWAY FROM BED
Where are bed bugs found inside dwellings?

Basic Inspection Tips
Check for small stains on furniture and bedding
Look for shed skins, amber in color Check crevices Check screw and nail holes Turn over furniture to check
underside Pull out drawers and inspect all sides
Primary Bed Bug Harborage
~70%5 feet
Secondary Bed Bug Harborages
~23%
“Other” Bed Bug Harborages
~7%
Lessons Learned
Waiting too long makes an infestation impossible to completely eradicate Active surveillance continues Quick response to new sightings
Must be a carefully coordinated effort Must have the support of the property
owner and ALL tenants Pick up of infested materials must be timely
Education and ongoing assessments are a must
Lessons Learned
Must identify barriers to success Languages and Literacy $$$
New or “gently used” replacement items Laundry Relocation
New Tenants Reducing the “stigma” of reporting
General Protection Tips: Home Visitors Carry as few extra items with you as possible Do not bring bags or personal items inside Consider bringing a portable stool, and sit
toward the middle of the room If stool not possible, sit on hard chair Do not sit on beds or plush furniture Check clothing after visit and before entering
car Put belongings in clear plastic bags
Protection Tips: Field Workers Use separate clothes and shoes for
field work Shake clothes outside before
entering car Change clothes at work Seal field clothes in clear plastic bag
for laundering Inspect own living and work space
regularly
Protection Tips: In the Office Limit personal belongings clients
bring in Limit plush furniture Inspect office regularly Hire pest control at any sign of bed
bugs
Protection Tips: Maintenance Workers Wear Tyvek suit or other coveralls Seal coveralls in plastic bag after use
and discard Dedicate a vacuum for pest control
BUG DETECTING DOGS
COULD BE THE FUTURE OF INSPECTIONS
MUCH QUICKER
SIGNIFICANTLY MORE ACCURATE
BED BUG DOGS ADVANTAGES PROVEN TO BE 96% ACCURATE
CAN INSPECT A ROOM IN A MATTER OF MINUTES
ARE A MARKETING MAGNET
BED BUG DOGS LIMITATIONS CAN NOT SEARCH UP HIGH
WORK BEST WHEN PAIRED WITH SAME HANDLER
NEED REINFORCEMENT TRAINING ALMOST DAILY

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

Now What…
Bedbug Policy Task Force Policy Change
Reducing risk factors Curbside bedding/furniture pick-up
Addressing areas of concern Used furniture and clothing operations
Increase funding to treat/support treatment Public Education
Increase access to educational materials Reduce stigma
MISSOURI LEGISLATIONBeg Bug Bills Last
Session Senate Bill No. 846 House Bill No. 1207
Key terms: negligence, implied habitability
