My question involves landlord-tenant law in the State of: louisiana

I moved into a house in denham springs, louisiana in march of this year. The house is infested with cockaroaches. And now I found out that there are bed bugs in the house. According to the pest control man, bed bugs have been in the house for at least a year. Turns out that my landlord was informed of the situation and just never informed me. This explains the mysterious bites my children and I have found on our arms and legs.
Can I legally break the lease with this information? I can't live like this anymore.
