I moved into my new sublet for the summer a week ago. The first day I moved in I spent 6 hours cleaning and wiping literally every surface. Then after setting in, the next day, I had a fly problem where dime-sized flies were somehow getting into my room.
Turns out, they were coming in through my loose window so OFC duct tape became the solution. The flies did stop appearing though. But currently in the vacuum are 6 flies, 2 spiders, and a house centipede. I think I have dealt with more bugs this past week than I ever encountered in my life. (vacuum has been emptied)
