What kind of flies are these? ID please!
Hi everyone!
I have had a phorid fly issue in my apartment for a bit that has gotten much better with Invade Biodrain. However, recently I noticed a different kind of fly that got stuck in a UV vacuum trap I have in the restroom. There are two there currently that were not there a few days ago and I have no clue what they are! I know they aren’t phorid or fruit flies, but no idea otherwise.
For extra information, I do not have any plants at all and I live on the top floor. Like I said, I keep my drains closed and use the aforementioned treatment consistently. I just moved in about two weeks ago and had the apartment professionally cleaned before moving, so no rotting food anywhere. The dishwasher filter and rubber gasket in the garbage disposal are both clean; I haven’t been able to check the refrigerator condensation pan, but the flies aren’t really gathered around that area and are more spread out around the apartment. I have a balcony, but I don’t keep the door open and I do have a large mosquito net covering the door for when I go inside and out. I do not keep any food or drinks out.
I have recently started pouring simmering water down all of my drains each night because a neighbor suggested it; she said she had a couple gnats over the summer (she let me borrow her Zevo and I saw there were phorid flies, but only 3 and she said that’s all she really had and they went away after pouring boiling water down the drains). I’m not sure if that could have anything to do with it.
I really don’t want to deal with a new bug infestation! I HATE the phorid flies already so a brand new fly to try and figure out would be a nightmare. If anyone can help please let me know! I have attached closeup photos and a picture with one of the phorid flies caught in the same trap for comparison.
