I don't think i've ever seen a bed bug ever in my life. No joke. Unless my understanding of them is severely limited and narrow. And nocturnal insects qualify (mosquitos, little flies that come to the light etc etc)
I was completely surprised to hear recently this is still a problem in western countries. A famous example would be a guy in US who torched a rented car because he wanted to get rid of bed bugs in the back.
Now, i am aware of the little ones, the "invisible ones", but this bigger, that you can see, no wai! Clean sheets ftw!
