William - You probably don't have fruit flies at all. You probably have sewer flies, also known as moth flies. They are probably coming from the bathroom. If you could take a photo, I could tell you exactly what you have and what to do about them.

Hello, I have an odd question. I’ve been noticing the occasional fruit fly in my office area/washroom/work areas which are located in the basement of our building. I don’t allow any kind of food on this level of the building, nor any drinks outside of water in resealable bottles and then only in designated areas with restrictions. Most of the time there’s no one else on this level of the building and if there is I’d likely notice them bringing in food or other drinks. I haven’t seen any fruit flies in the collections storage areas (woo!). There are exhaust vents in my work area and in the washroom. The washroom vent empties out into a crawl space under part of the building and I’m not sure where my work area vent goes but potentially the same spot. Some of the fruit flies have been getting stuck in the sticky trap in the washroom which is located by the door jam. I haven’t noticed any fruit flies in other traps so I’m thinking they may be coming from there and potentially from the crawl space through the vent, though why they’d be in there I don’t know. The main level of the building does have food friendly areas such as offices and a food service area for events but there doesn’t seem to be an issue up there and I don’t know how they would continually be getting down here as there is always at least one closed door to get, though generally more. It’s a scent free workplace so it’s not like I’m wearing eau de pourriture fruits perfume down here! Any thoughts?
