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

BED BUGS ON CAMPUS

• WHERE DO THEY COME FROM?

• WHY ARE THE PROBLEMS SO SEVERE?

USED FURNITURE

INTERNATIONAL TRAVEL

LOCAL COMMUNITY

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

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

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

EVALUATION

• All inspections and reports documented

• Create a data base

• Analyze data on regular basis

PREVENTION

• EDUCATE, EDUCATE, EDUCATE

• BEWARE OF USED FURNITURE

• PREPARE SPRING BREAK TRAVEL ADVISORY

• COULD BE COMMUNITY PROBLEM

PREVENTION TOOLS

• INVERTED SEAM MATTRESSES

• MATTRESS COVERS

• WELL MAINTAINED FACILITY

• WELL EDUCATED RESIDENTS/STAFF

INVERTED SEAM MATTRESS

FACILITY MAINTENANCE

• SEAL UP ALL CRACKS

• SEAL WALL PENETRATIONS

• ELIMINATE ALL HARBORAGES

EDUCATE THE RESIDENTS

• PUBLISH THE DO’S AND DON’TS

• ENCOURAGE THEM TO REPORT EVEN SUSPECTED BED BUGS

• MAKE IT A PART OF THE STAFF/RESIDENT ORIENTATION
