2. 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?

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

4. BED BUGS ON CAMPUS WHERE DO THEY COME FROM?
WHY ARE THE PROBLEMS SO SEVERE?

5. USED FURNITURE

6. INTERNATIONAL TRAVEL

7. LOCAL COMMUNITY

8. 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)

9. 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

10. 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

33. THE SECURITY THAT THE BED BUGS ARE DEAD
PRICELESS

34. ROOM TREATMENT
VACUUMING
STEAMING
APPLYING A RESIDUAL

35. VACUUM THE CARPET THOUROGHLY VACUUM THE CARPET AREAS
CAN BE BEFORE OR AFTER THE HEAT TREATMENT
DISPOSE OF THE VACUUM BAG

36. STEAM TREATMENT PULL THE CARPET BACK FROM BASEBOARDS
STEAM ALONG ALL EDGES AT THE JUNCTION OF CARPET AND WALL

37. RESIDUAL APPLICATION
APPLY RESIDUAL INSECTICIDE ALONG JUNCTION OF WALL AND FLOOR
APPLY DUST BEHIND ALL WALL PLATES

38. 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

39. WHOLE ROOM HEAT
THERE ARE COMPANIES THAT ARE PERFORMING WHOLE ROOM HEAT
TWO DIFFERENT ENERGY SOURCES
PROPANE
ELECTRICITY

40. 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

41. WHOLE ROOM HEAT USING ELECRICITY
115 VOLT HEATERS REQUIRE 6 15 AMP CIRCUITS TO OPERATE
460 VOLT HEATERS NEED A GENERATOR
GETS RATHER EXPENSIVE

43. ELEMENTS OF IPM Education Communications Inspection Identification
Exclusion
Sanitation
Treatment Strategy
Evaluation

44. EDUCATION
Institutional staff
Pest control provider
Residents

45. COMMUNICATIONS Key element between participants
May take a variety of forms
Addresses problems, solutions, and prevention

46. INSPECTION Performed on an as needed basis Results documented
Provides early intervention and validation of success

47. Click for video

48. IDENTIFICATION Sample of pest is important Proper ID is vital
Leads to proper plans for control

49. EXCLUSION DIFFICULT TO DO FOR BED BUGS
WELL MAINTAINED FACILITY HELPS GREATLY
SIMPLE THINGS CAN HELP

50. TREATMENT STRATEGY Developed with safety as important factor
Utilizing all of IPM tools
Can this strategy be sustained

51. EVALUATION All inspections and reports documented Create a data base
Analyze data on regular basis

52. PREVENTION EDUCATE, EDUCATE, EDUCATE BEWARE OF USED FURNITURE
PREPARE SPRING BREAK TRAVEL ADVISORY
COULD BE COMMUNITY PROBLEM

53. PREVENTION TOOLS INVERTED SEAM MATTRESSES MATTRESS COVERS
WELL MAINTAINED FACILITY
WELL EDUCATED RESIDENTS/STAFF

54. INVERTED SEAM MATTRESS

55. MATTRESS COVER

56. MANUFACTURERS University Sleep Products –

57. FACILITY MAINTENANCE SEAL UP ALL CRACKS SEAL WALL PENETRATIONS
ELIMINATE ALL HARBORAGES

58. 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
