My son was away from his apartment for a month. No garbage was left in his room. He came home and there were flies everywhere he even found lots of them inside his refrigerator and freezer. He killed as many as he could but still has flies appearing around the apartment. He cant find the source. The landlord will come in and spray but the source has not been found. the landlord said its not unusual for them to end up in your refrigerator. I have never heard of such a thing. (these are not fruit flies). Any thoughts on this?

Three months ago I was moving out of state for the summer, so I made plans to end my lease and put my furniture into a storage unit. About a month before moving out I hired a pet sitting service when I went out of town for a week, and just a week before moving I discovered my cat had fleas. They were in my furniture and carpet as well. It wasn't a massive infestation, but it was enough that I couldn't get them fully eradicated before moving. With the move being pretty stressful and being behind schedule I didn't want to deal with a fogger and re-homing for the night. I opted to use flea shampoo, Advantage, and three daily combings on the cat. I used Adams Flea and Tick Home spray on all furniture and carpets several times over the week, and used Vet's Best (supposedly non-toxic, though I learned later that cedar is not good for cats) daily. We vacuumed daily and on the last night in the apartment I steam cleaned the carpet (I was planning on doing this before the fleas showed up). My wife had used a similar treatment plan (plus DE, which I did not want to mess with) several years ago when her cat picked up fleas from a hotel on a cross-country drive, and it took several weeks but worked and her apartment has been flea-free ever since. We did the move, gave my cat some Capstar when we got to our home for the summer, and she did not bring any fleas into the new home. I am not so optimistic about the furniture, which is sitting in the climate-controlled storage unit and which I'll be picking up and moving back into my new apartment in a week and a half. I intended to give a final spray of Adams in the storage unit, but it was packed from front-to-back, so I couldn't reach 3/4 of the items, and I was running almost a full day late on my move so I forgot anyway. I also forgot to replace my vacuum bag. Obviously, I'll do that before bringing it into the new home. I'm primarily concerned with the fabric sofa, the bed, and the fun 6-foot cat tower. I initially hoped that there would be enough time in the storage unit that the life cycle would break, but I'm getting nervous now that my move-in is coming up. Things I see online suggest that while 12 weeks without a meal may be enough to break the life cycle, it also might not. I'm looking for advice on whether any remaining fleas have likely starved (I doubt this, but maybe my treatments will have made them weaker?), and what kinds of preventatives I should consider as I reclaim my furniture. My cat is now on monthly Advantage treatments to prevent this from ever happening again. If need be I can move everything in, do a fogger, and go to a hotel with my cat for the night. But I'd like to save this as a last resort because I feel like setting off a flea bomb on my first night in a new apartment is not the best way to start out with my new landlord. My wife and parents suggested setting off a fogger in the storage unit the day before I move furniture. Unfortunately, the unit's walls are ~10 feet high, but the ceiling is ~14 feet, so there is a big gap between the top of my unit and the top of the building. I think this has something to do with the fire code. A fogger would quickly spread beyond the unit and into the whole building, so this is not an option. Thanks in advance!
