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 • Erik Foster, MS, Medical Entomologist, Michigan Department of Community Health and the Michigan Bed Bug Working Group • Dini M.

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.

Bed bug Cockroach Site for pesticide absorption None here Can’t climb smooth surfaces. Pads vs. No Pads Easily climbs smooth surfaces.
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 TREATMENTINSPECTION
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? Mattresses
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
Secondary Bed Bug Harborages ~23% “Other” Bed Bug Harborages ~7% Primary Bed Bug Harborage ~70% 5 feet
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
