A bed bug infestation found on a Philadelphia city bus.
Crystal Lopez shot the video.
She said:
Right before I was to pull the cord, I feel like this itching, burning feeling on my arm. It was in its entirety from my wrist to my armpit.
I felt like my arm was on fire. Like my whole arm was on fire and itching all at once.
The bus was immediately pulled out of service. Officials said they are also in the process replacing upholstered seats with plastic. 
One way bed bugs can spread in public spaces is through personal belongings. Experts say a book bag or handbag placed near an infestation could allow them to climb aboard, and you can then take them home.
