Hi,
Just to be clear, I have volunteered at homeless shelters before and I am very aware of the stigma homeless people get. However, I was walking on the street today and due to the strong wind, a homeless' man's cardboard sign hit me on the leg a few times, before flying off. What are my chances of being infested, if the man's cardboard was infested? I am not worried about the fact that he is homeless, but about the fact that bed bugs do like cardboard.
