Bed bugs l.jpg
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 l.jpg
WHY DO WE NEED IPM

  • INCREASED RESISTANCE TO CURRENT INSECTICIDES

  • EXPOSURE OF RESIDENTS TO INSECTICIDES

  • SUSTAINABLE SOLUTIONS

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)


How small are they l.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

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

Room treatment l.jpg
ROOM TREATMENT

  • VACUUMING

  • STEAMING

  • APPLYING A RESIDUAL


Vacuum the carpet l.jpg
VACUUM THE CARPET

  • THOUROGHLY VACUUM THE CARPET AREAS

  • CAN BE BEFORE OR AFTER THE HEAT TREATMENT

  • DISPOSE OF THE VACUUM BAG


Steam treatment l.jpg
STEAM TREATMENT

  • PULL THE CARPET BACK FROM BASEBOARDS

  • STEAM ALONG ALL EDGES AT THE JUNCTION OF CARPET AND WALL


Residual application l.jpg
RESIDUAL APPLICATION

  • APPLY RESIDUAL INSECTICIDE ALONG JUNCTION OF WALL AND FLOOR

  • APPLY DUST BEHIND ALL WALL PLATES


Which residuals l.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


Whole room heat l.jpg
WHOLE ROOM HEAT

  • THERE ARE COMPANIES THAT ARE PERFORMING WHOLE ROOM HEAT

  • TWO DIFFERENT ENERGY SOURCES

    • PROPANE

    • ELECTRICITY


Whole room heat using propane gas l.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


Whole room heat using elecricity l.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
