Occasionally we'd have books returned to the library that were infested with bedbugs. We knew to quickly put the books into multiple plastic bags, tape them shut and dash out the back door to toss them on the picnic table until we could write down the barcodes. They then went into the dumpster. We never got bedbugs in the library but it grossed us out. My daughter's BIL & DH run a rental business at a beach in the US. Even though they have expensive home rentals they still find bedbugs once in a while.
I did find this on the web:
Without a doubt, bed bugs can survive over a year. They can also survive that time without a blood meal.
If I really wanted the machines I'd call a pest control and see what suggestions they have!
