pest infestation

a week ago and the the very first night I noticed I had roaches and fleas in my apartment. I reported it the very next day and the apartment manager was quick to schedule a local company to come and fumigate. They came three days in a row to spray, but the problem has not been resolved yet. My daughter and I have flea bites all over and not to mention the fumes are causing us to get headaches and my daughter has been having nose bleeds. The apartment is infested with roaches and I cant have any food in my pantry because they are all over it, forcing me to keep everything in my fridge. I have asked the property manager to move me to another unit but he refused and gave me the option to break my lease. The problem is I dont have the money to pay another deposit, app fees, etc. I cannot keep living with pests which are harmful to both my daughter and I. What can I do?
