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?
![Page 3: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/3.jpg)
WHY DO WE NEED IPM
• INCREASED RESISTANCE TO CURRENT INSECTICIDES
• EXPOSURE OF RESIDENTS TO INSECTICIDES
• SUSTAINABLE SOLUTIONS
![Page 4: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/4.jpg)
BED BUGS ON CAMPUS
• WHERE DO THEY COME FROM?
• WHY ARE THE PROBLEMS SO SEVERE?

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)
![Page 9: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/9.jpg)
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

THE SECURITY THAT THE BED BUGS ARE DEAD
PRICELESS
![Page 34: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/34.jpg)
ROOM TREATMENT
• VACUUMING
• STEAMING
• APPLYING A RESIDUAL
![Page 35: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/35.jpg)
VACUUM THE CARPET
• THOUROGHLY VACUUM THE CARPET AREAS
• CAN BE BEFORE OR AFTER THE HEAT TREATMENT
• DISPOSE OF THE VACUUM BAG
![Page 36: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/36.jpg)
STEAM TREATMENT
• PULL THE CARPET BACK FROM BASEBOARDS
• STEAM ALONG ALL EDGES AT THE JUNCTION OF CARPET AND WALL
![Page 37: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/37.jpg)
RESIDUAL APPLICATION
• APPLY RESIDUAL INSECTICIDE ALONG JUNCTION OF WALL AND FLOOR
• APPLY DUST BEHIND ALL WALL PLATES
![Page 38: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/38.jpg)
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
![Page 39: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/39.jpg)
WHOLE ROOM HEAT
• THERE ARE COMPANIES THAT ARE PERFORMING WHOLE ROOM HEAT
• TWO DIFFERENT ENERGY SOURCES– PROPANE– ELECTRICITY
![Page 40: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/40.jpg)
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
![Page 41: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/41.jpg)
WHOLE ROOM HEAT USING ELECRICITY
• 115 VOLT HEATERS REQUIRE 6 15 AMP CIRCUITS TO OPERATE
• 460 VOLT HEATERS NEED A GENERATOR
• GETS RATHER EXPENSIVE
![Page 42: Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS](https://reader033.vdocument.in/reader033/viewer/2022051218/568159bd550346895dc711f7/html5/thumbnails/42.jpg)
