Mrs. Z & I caught the "discount" ferry from Italy to Greece a few years back after taking the wrong bus to the wrong port. On a budget, we holed up in what they call airline seating for the overnight trip. Not looking forward to back pain after a couple weeks of hosteling, I slept on the floor next to the life jackets. In the early morning, the lights came on for an announcement and I noticed what I thought were large lice crawling about me and my backpack, some attached to my skin. "Are these lice? They're huge!", I said with disgust. The Malaysian couple we'd made acquaintance with chuckled at me while calmly inspecting their luggage and pinching blood engorged bugs with a napkin. "These are bed bugs," he grinned nonchalantly, "and back home they get 3x this size."
The little chompers were living and breeding magnificently in the life jacket storage area, undisturbed & fed well by the constant barrage of passengers between Bari & Patra. We recently discussed going to Malaysia(she's forgotten this episode, I think) on a future trip, so if you know my wife...please refrain from reminding her of the gargantuan BED BUGS that live there
P.S. we continued to find these for weeks afterward. They especially enjoyed hiding in the spine of an Irvine Welsh novel.
