I had a terrible, torturous phorid fly infestation (nightmare) for a number of months. No one could figure out where they came from or why they suddenly appeared.
I thought they might be from my drains, so I poured various entomologist-recommended bacterial drain cleaners down them for a long time. It made no difference. But when the weather turned colder they went away.
I guess my question is: If they go away in the colder weather and arrive in the warmer weather, then what does that say about where they are coming from?
Because they aren’t coming from my drains, fridge, vents, door, or windows. And I never, ever leave out garbage or food.
It just doesn’t make any sense to me!
I know they will come back in warmer weather, and I just wish I knew how to stop that from happening!
FYI, I live on the second floor in an apartment in the Dallas area.
Can anyone help me understand?
