Those are psychodid flies, so drain flies, sink flies, moth flies, or sewer 
gnats are all good common names. I prefer moth flies.

Hello!

Sorry I didn't get back to everyone yesterday, I ended up 
needing to move some shelving units. The general consensus seems to be on drain 
flies, thank you everyone that took the time to reply. I've attached an image I 
took of a trap that shows four flies right together. Hopefully the quality is 
enough to make an identification, I think a macro lens needs to be my next 
purchase!

Thank you everyone in advance.

fruits. One species develops on fresh fruit, in fact.

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

Hello Tom (and All),

Thank you for the positive identification. I’ve placed strips 
of tape over various drains and vents to see where they’re coming from and then 
I’ll deal with them.

Thanks again.
