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.
