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. 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.

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.
