Do I have grounds to sue for continuous bed bugs issues?

I moved in my apartment in February of 2014. Two weeks later, I saw a bed bug. I notified the landlord. He contacted a pest control and they came out to inspect. Upon inspection, they said my apartment was clear. In May, I started getting bit again and found another bug. I notified the landlord and he proceeded with treatment. After undergoing treatment in my unit, my neighbor, in an adjoining unit then came forward and said they had bed bugs as well. Upon inspection of the apartment pest control determined the unit was highly infested with bed bugs. The manager of my apartment complex also said it was clear. The bug in my unit came from theirs. It’s now November of 2014 and I still have bugs.
