More bed bugs are found at Ingham Regional Medical Center.
Health experts will meet Thursday to discuss the problem.
Last weekend, the hospital fumigated two rooms on the sixth floor of its Greenlawn campus after the insects were discovered by a nurse.
According to the Lansing State Journal, nurses noticed the bed bug on a patient who was in both of the rooms that were fumigated.
Ingham sprayed for bed bugs a few months ago.
