I moved into an apartment unit about 2.5 weeks ago. Since move in, the unit has had a serious fungus gnat issue. I could see several of them behind the blinds of every single window in the apartment on move in day. You would see some flying around but most of them were in the windows. I flushed cleaner down the drains and plugged all drains, and gnats were still appearing. So was able to confirm the fungus gnats were NOT coming from the drains. Management sent pest control about a week ago. The issue lessened, but live gnats still present.. just fewer in number. Management is not going to do anything more to eliminate the issue so unfortunately I am on my own here. PLEASEEEE help me out here.. How do I get rid of these terrible pests completely, once and for all!? I have done light traps, sticky traps, sprays, dishes of vinegar.. with NO LUCK GNATS STILL APPEAR. Also, where could they be coming from? I know it’s not my drains and I have no house plants. The apartment had this issue when I moved in. Any advice is thoroughly appreciated
