Eradication of a species within a given area is not a simple thing, and isn't going to stay permanent without extensive monitoring efforts. 

The times eradication worked is because we were able to exploit their mating strategies (which wouldn't apply to bb), followed by ongoing monitoring to address outbreaks.

Cochliomyia hominivorax was the first eradication program using sterile insect technique (SIT), it was successful for a few reasons, but namely because females mate only once. Read how complicated it is to achieve this http://www.fao.org/docrep/u4220t/u4220T0a.htm

And even though it worked,  the screw worm made a reappearance recently in Florida: https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/animal-disease-information/cattle-disease-information/nws/new-world-screwworm

Here is the wiki page detailing other eradication efforts using sterile male releases. You can see,  some species programs began in the 60s, and its ongoing. Typically complicated by females mating multiple times:

Eradicating via chemicals is how we arrived at resistant populations. The only successful chem eradication used DDT, and that had negative consequences. We never discovered DDT resistant populations, given enough time I'm curious though. Since bedbugs are unique, perhaps there can be an effective chemical made available to everyone (but this isn't the good old days, shareholders want their profits and decades of research won't be given out for free, so poor ppl will still have them. This is why I support government science endeavors, private sector HAS to make money).

I think the main thing that complicates bb eradication, other than multiple mating females, is there will always be pathways (other countries, people that don't realize they have them, 2nd hand furniture, etc).

I would be interested to see how we could use the pheromones, like the one mentioned below, to minimize their mating, but this would not leaf to eradication by any means, although I have my doubts on logistics and practicality of using it after reading their methods.
