Walking Bed Bugs

While bed bugs are known to travel unit to unit, they are also known to walk from building to building in severe and exceptional cases. Eric Hardebeck of Permakil, an American pest control company, reported bed bugs crawling through an alley in broad daylight, climbing up the sides of a building and crawling along telephone wires to enter into an apartment building adjacent to the alley. Bed bugs were found running out into the street, and some had been run over by cars. 

The bed bugs had survived in mattresses discarded in the alley and by feeding on homeless people who were using the mattresses. The infestation had reached such high levels that the 

bugs were mobile outside during the day.
