Ants/mold

Hello everyone,

I had a lease that started in February this year. I had to move out of my first unit due to a leak because of rain and which caused mold. (There was a lot of it so I’m sure they just covered it and went on to give me the unit). I also found mold/smoke paint in my closet prior to moving. Anyways, they let me move into another unit in October and this one is infested with ants. I’ve been dealing with them since October and they have brought pest over maybe twice and maintenance twice. They keep putting traps and liquid bait and it’s doing nothing. I complained again and they added caulk in certain areas last week and still dealing with ants. I keep it clean and I even cleaned the walls/floors to see if that helped, and nothing. I don’t keep food around. It’s very frustrating because I dealt with mold at the last unit and now this. On top just now I noticed above the shower head there is a yellowish spot assuming there’s a leak from the unit above coming down into mine. (This was an issue at my last unit but they just insisted there’s no mold there just from the water leaking from shower above). Is there anything I can do about this? I would love to just break the lease and move somewhere else. It’s just all frustrating especially because I have a 3 year old who is terrified of ants. Thank you in advance.
