Are you sure they're fruit flies? I deal with a similar issue earlier this summer. We had tons of what I thought were fruit flies in our collections area, so I posted a photo of them on this listserv. By doing that, I was informed that they were actually "Black Fungus Gnats," which were an indicator of excess moisture in our collections area! Would you be able to post a close-up picture of your flies?

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 fr om the crawl space through the vent, though why t hey'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?
