I own an apt in a co-op in queens. I have a tenant who sublets it from me. she recently got bed bugs. she contacted mgt, and mgt said it is her responsibility. she paid for exterminating. after a few weeks, she felt they had returned. She called 311, they contacted the management.

I didn't know much about this but looked it up online and discovered the landlord is responsible to address this. I also gather that the landlord in this case is not me, but them, the co-op corporation. I then asked management to reimburse my tenant and I offered to reimburse her too after I discovered what I think is the law on this.

at first, mgt said it is not on them, but on my tenant. they blamed her.

now the management is inspecting surrounding apts., doing what I think they should have done immediately. I think they may have researched this and are aware that they are at fault, especially after 311 and HPD contacted them. that's a telltale sign of culpability to me; 311 and HPD contacted them and not me.

my questions are:
who is responsible to address her bed bug problem and pay for it; is it me, or the co-op?

and since we paid, are we entitled to get that money back?
