It’s not that bad if you are in a single house or have decent neighbors. My extended family had them from some holidays hotel and one professional extermination was enough. (That being said, I live in Europe - hollow walls are a rarity)
I heard it’s a huge problem if you are living near some slob that is a neverending source of the infestation. If one has a neighbor that sacrificed his body and soul to the bedbug god and refuses to let exterminators in, then indeed, the only possible choice is to GTFO.
For fuck’s sake Diogenes, you could chill after 23 centuries. Plato is crying under the table.
