  22. 22. Questions & Answers Q. Is this bite on my leg from a bed bug (which I think I must have gotten at work)? A. Highly Unlikely. A bed bug only feeds on a person who is completely still, which predominantly means sleeping. Q. Bed bugs have been observed/caught in our office building. Is the office building infested? A. Highly Unlikely. There have been no known cases in DPH of Worksite Infestation. One or Two bedbugs does not make an infestation. 22
  23. 23. Questions & Answers Q. Bed bugs have been observed/caught in our building. Is it possible that if I bring as few as one home to my house that my house can become infested? A. Not Likely. To cause an infestation in your home, a bed bug would not only need to attach itself to you or your property, but would need to stay attached all the way to your house, get to your bed, and lay eggs. If all of this does occur, then take the necessary steps to eliminate them. Q. I suspect a client may have bed bugs because they told me that they have them at home. What should I do when client arrives for an appointment? A. Check the area where client was sitting. If client brought items to the appointment, check areas where items were placed. If any insects are observed immediately call Facilities Management. 23
  24. 24. 1380 Howard Protocols for Office Environment 1) Scheduled monthly placement and inspection of insect traps/monitors at each site/program location by Pest Control Vendor and/or Facilities Team, with a report of findings submitted and discussed with Facilities staff at each site. 2) If bed bugs are suspected or sighted, Facilities Team or Program Manager or designee will contact BEHM Inspectors Mario Oblena 252-3826 and Joseph Ossai 252-3892 for assistance. The detailed report of the findings should be supplied to the inspectors along with any other information from the Pest control vendor. 3) If the suspect carrier is a client/visitor, we should inform them that their visit or session has ended and they need to leave the premises to prevent possible contamination of clinic occupants. Facilities Team can/should make arrangements to contact BEHM and the bldg manager for the client/visitor if possible. 4) If the suspect carrier is an employee, their supervisor or Facilities Team should share the suspicion or findings with the employee, ask if there is an issue at home, and contact Human Resources on the next step. Facilities Team will make arrangements to vacuum the area and /or arrange for more intensive treatment by Pest Control vendor, under the guidance of BEHM. 24
