I have lived in the same apartment for four years. There has been the occasional mouse, but in the last 6 months, I am catching as many as 2 mice a week. I have notified my landlord in writing, but all he did was give me a package of glue traps and tell me to submit my mousetrap receipts and deduct it from my rent. In August, and again last week, I requested, in writing, that he really do something about this (as in, get an exterminator), but he has not yet done anything about it because he claims that it is not "an infestation." What are my options, at this point?
