Life History Characteristics ShowThat Bed Bug Numbers Can QuicklySkyrocket … (Early Detection and Treatment are Very Important)  Eggs  Glued in place  1 – 12 eggs / day / female  A single female can produce ~150 eggs  Hatch in 6 – 17 days  Nymphs (immature bugs)  Five nymphal stages  Require a blood meal in order to grow  Adults (males & females)  Require repeated blood meals  Can live 12 – 18 months  Can survive months of starvation

  22. 22. If you wake up with itchy, red welts that weren’t there when you went to bed, perhaps its bed bugs. BED BUGS BITES: • Initial bite is painless • Resemble bites from other insects & kin • Some clues that it may be bed bug bites: • Typically are on exposed skin • Often in groups or rows Confirmation based on finding bed bug evidence
  23. 23. Survey (spring/summer 2009): • 474 individuals with verified bed bug infestation in dwellings • Apts (66%), single-family homes (15%), condos/townhomes (9%), shelters (7%), dorms (2%), long-term care (<1%) • Chicago, N.Y., Cincinnati, Louisville, Atlanta, L.A., & Miami• ~70% of people had an allergic reaction to bed bug’s injected saliva; ~30% had no reaction - Swelling - Welts - Severe itching (hrs to days)• Difference in reactivity due to age - Elderly (>65 years old--42% with no reactions) - Children (1-10 years old--41% with no reactions [note: very small sample size])• No significant difference in reactivity for: - Males vs. females - Ethnic groups
  24. 24. Injury From Bed Bugs• Allergic reaction in ~70% of humans • Welts • Severe itching• Anemia• Asthma• Scratching of bites increases inflammation, can lead to secondary bacterial infections• No conclusive evidence of disease transmission (reviewed by Goddard & deShazo. 2009. JAMA 301(13): 1358-1366)

  35. 35. COAAA has stayed on the forefront of thebed bug problem in central Ohio.• Three staff on COBBTF• Clinical practices group meetings• Written policy• Safety committee tracking locations• Trainings (new staff)• Chairs and dryer
  36. 36. Things to consider when entering aninfested area: • What are you wearing? – Light colored clothing – Booties – Tyvek suits
  37. 37. Things to consider when entering aninfested area: • Are you going to need to sit? – „bed bug‟ chairs
  38. 38. Things to consider when entering aninfested area:• How is the client going to feel? – Stigma attached – Provide education – Company policy – Ensure therapeutic relationship
  39. 39. Things to consider when entering aninfested area: • Where do you go after visiting an infested area? – Carry extra clothes – Carry trash bags
  40. 40. WHAT NOT TO DO Dont spray yourself with mosquito repellent (DEET). It is useless against bed bugs! Dont use rubbing alcohol indiscriminately! Alcohol is VERY flammable, and it should NEVER be sprayed indoors. DON‟T use Diatomaceous Earth indiscriminately Dont EVER spray yourself, your clothing, or your shoes with ANY insecticide! Many insecticides can be absorbed through your skin.
  41. 41. After treatment• Mattress covers• Monitor environment• Provide support for PTSD
  42. 42. Support for Professionals• Address ongoing feelings• Use PPE as needed to prevent exposure• Discuss need for dryer
  43. 43. Bed Bugs in the WorkplaceSurvey the Premises• Train your staff to know what bed bugs look like and how to identify them.• Carefully inspect the area where the suspected bed bug was found as soon as you can.• Because bed bugs like to hide, it is important to know where to look for them: • check the folds and seams in upholstery, lockers, baseboards, cubicle walls, furniture joints and corners, electrical outlets, switches, piles of papers and other nooks and crannies.
  44. 44. Bed Bugs in the WorkplaceRespond To Your Findings: If you find more bed bugs...• Don’t kill them or crush them! It is impossible to make a positive identification from smashed bug parts!• Put the live bug(s) in a pill bottle or a tightly sealed plastic bag so that your pest management professional (PMP) can make a positive identification.• Try to isolate the area where the bug(s) were found.
  45. 45. Bed Bugs in the WorkplaceAct Quickly:• Contact your PMP immediately.• Verify bug, request treatment plan and follow-up.• Treatment should not occur while people are in the area.
  46. 46. Bed Bugs in the WorkplaceDebunk the Misconceptions• When one or two bed bugs, are found, most people assume that there are many more in the building, which isn’t always the case.• Bed bugs are a pest, but they shouldn’t be a cause for panic. There is no need to suspend your operations, especially if the bed bugs were only found in a few isolated places.
