<human>: Can you condense the text into a few key points?

When I went to sign the sublet lease they told me they'd need to a do a background check for things like previous evictions, etc.. and then she mentioned bed bugs. I told her up front that I had had bed bugs in the apartment I had lived in before I studied abroad for a year in Germany but the entire unit (all flats in the house) had them as well and I had since been bed-bug free and destroyed all previous items in the bed bug infested apartment.

I have lived in a dorm in Germany for a year and for a few months at my parents' house since then and I clearly have no more traces of bed bugs.
I also don't understand how I can be held accountable for the bed bugs. I mean, if they were looking to buy the unit or maybe if I had been landlord at the infested unit and was applying to be landlord for them, then it would be more valid I suppose. 

But I don't think it's fair to judge a tenant with a good tenant history (no evictions, rent always on time, no major losses to security deposit) for the problem. It seems unfairly discriminating.

I have no other options of places to live and I need to be in the city for school! 

What should I do?
<bot>: a previous apartment, had a bed bug department, that was years ago, now a prospective renter sayin' no. is that even fair or should I beware?
