seriously! And they don't go away. You have to nuke them, seriously nuke them.
The problem I'm hearing about is the bugs that are becoming immune to the toxins used in sprays. (shuddering commencing in 5... 4...) Could just be a rumor.
I remember hearing about Bed Bugs as something that had vanished long ago. They suddenly re-appeared in my consciousness three or so years back. I knew about lice, but "bed bugs" were from that "nighty night, sleep tight, don't let the bed bugs bite" rhyme.
Sleep tight seemed to refer (IIRC) to beds held up by chords that needed tightening to be comfortable. Could they have been to hold up sheets, rather than mattresses, so bed bugs could be removed during an infestation? Rather than making a mattress that is expensive, that just gets thrown out when the bugs inevitably come back?
Another rumor: eating onions acts as a natural bug spray, as bugs are less willing to bite someone who eats lots of onions. Don't know if I believe that one...
