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
WHY DO WE NEED IPM
  • INCREASED RESISTANCE TO CURRENT INSECTICIDES
  • EXPOSURE OF RESIDENTS TO INSECTICIDES
  • SUSTAINABLE SOLUTIONS

  • 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
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

room treatment
ROOM TREATMENT
  • VACUUMING
  • STEAMING
  • APPLYING A RESIDUAL
vacuum the carpet
VACUUM THE CARPET
  • THOUROGHLY VACUUM THE CARPET AREAS
  • CAN BE BEFORE OR AFTER THE HEAT TREATMENT
  • DISPOSE OF THE VACUUM BAG
steam treatment
STEAM TREATMENT
  • PULL THE CARPET BACK FROM BASEBOARDS
  • STEAM ALONG ALL EDGES AT THE JUNCTION OF CARPET AND WALL
residual application
RESIDUAL APPLICATION
  • APPLY RESIDUAL INSECTICIDE ALONG JUNCTION OF WALL AND FLOOR
  • APPLY DUST BEHIND ALL WALL PLATES
which residuals
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
WHOLE ROOM HEAT
  • THERE ARE COMPANIES THAT ARE PERFORMING WHOLE ROOM HEAT
  • TWO DIFFERENT ENERGY SOURCES
    • PROPANE
    • ELECTRICITY
whole room heat using propane gas
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
WHOLE ROOM HEAT USING ELECRICITY
  • 115 VOLT HEATERS REQUIRE 6 15 AMP CIRCUITS TO OPERATE
  • 460 VOLT HEATERS NEED A GENERATOR
  • GETS RATHER EXPENSIVE
