As winter turned to spring we got a lot of mold on the ceiling and wall of our kitchen. We tried but could not get rid of it. Now that spring has turned to summer, we have a ton of little black bugs that have come to eat the mold (so that is why there was no mold when I moved in). These bugs don't bite, but they often fall from the ceiling and land in the most annoying places. Our new apartment is bug and mold free!
