Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS WAYNE WALKER ASSOCIATE CERTIFIED ENTOMOLOGIST UNIVERSITY OF FLORIDA DEPARTMENT OF HOUSING AND RESIDENCE EDUCATION
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 • INCREASED RESISTANCE TO CURRENT INSECTICIDES • EXPOSURE OF RESIDENTS TO INSECTICIDES • SUSTAINABLE SOLUTIONS
WHERE DO THEY COME FROM? WHY ARE THE PROBLEMS SO SEVERE? BED BUGS ON CAMPUS
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? • 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
Equipment for Heat Treatment 6 polystyrene sheets 2 heaters 2 box fans 1 oscillating fan Extension cords and power strip
Temperature Monitoring Thermometers Data Loggers
Room Setup for Heat Treatment Vials of Bed Bugs
Room Setup Under pillows on mattress • Live bed bugs • Data loggers • Thermometer sensors • Placement In cabinet Under mattress

Equipment • 2 Space heaters • $99.90
Equipment • 6 Polystyrene sheets (4 by 8 ft) • $137.76
Equipment • 2 Box fans • $27.34
Equipment • 1 Oscillating fan • $29.95
Equipment • 2 Thermometers • $17.94
Equipment Costs$312.89 • 2 Space heaters • 6 Polystyrene sheets • 2 Box fans • 1 Oscillating fan • 2 Thermometers • 2 Extension cords; power strip • Duct or packing tape
THE SECURITY THAT THE BED BUGS ARE DEAD PRICELESS
ROOM TREATMENT • VACUUMING • STEAMING • APPLYING A RESIDUAL
VACUUM THE CARPET • THOUROGHLY VACUUM THE CARPET AREAS • CAN BE BEFORE OR AFTER THE HEAT TREATMENT • DISPOSE OF THE VACUUM BAG
STEAM TREATMENT • PULL THE CARPET BACK FROM BASEBOARDS • STEAM ALONG ALL EDGES AT THE JUNCTION OF CARPET AND WALL
RESIDUAL APPLICATION • APPLY RESIDUAL INSECTICIDE ALONG JUNCTION OF WALL AND FLOOR • APPLY DUST BEHIND ALL WALL PLATES
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 • 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
MANUFACTURERS • Temp Air – http://www.temp-air.com/thermal/index.asp • Pest-Heat (manufacture of heat generating equipment) • http://www.pestheat.com/index.html • ThermaPureHeat – http://www.thermapure.com/bedbugs.php
ELEMENTS OF IPM • Education • Communications • Inspection • Identification • Exclusion • Sanitation • Treatment Strategy • Evaluation
EDUCATION • Institutional staff • Pest control provider • Residents
COMMUNICATIONS • Key element between participants • May take a variety of forms • Addresses problems, solutions, and prevention
INSPECTION • Performed on an as needed basis • Results documented • Provides early intervention and validation of success
IDENTIFICATION • Sample of pest is important • Proper ID is vital • Leads to proper plans for control
EXCLUSION • DIFFICULT TO DO FOR BED BUGS • WELL MAINTAINED FACILITY HELPS GREATLY • SIMPLE THINGS CAN HELP
TREATMENT STRATEGY • Developed with safety as important factor • Utilizing all of IPM tools • Can this strategy be sustained
