Bugs!

Not a great topic, but I'm at my wits end and losing battle after battle! I must win the war! We have been battling gnat like bugs, mostly around the kitchen area. I have seen these bugs before and associate them with garbage. I have looked everywhere for anything they may be attracted to and have found nothing and we keep our rv/home clean! I've set foggers. No result. I've poured liquid fire down the drains. No result. My bug guy says sewer flies But how they getting in? is there not a "p" trap? I placed a small container of apple cider vinegar (its supposed to attract and trap them) no result. They "flit" around in sink and in trash. Driving us mad! Cant set a sandwich down for 2 seconds! Theyre nasty and I'm about to burn it down! 38FLSA Pinnacle and I leave grey tank open although I've seen them with it closed. Anyone know what to do?

Sounds like drain flies. They live in the drain and feed off of the soap scum between the sink drain and the top of the water in the p-trap. Remove the p-trap and clean the tail pipe between the bottom of the sink and the end of tail pipe. You'll get the eggs and flies at the same time.

They look like a regular fly only much smaller. Gnats look entirely different and are smaller.

I doubt they're sewer flies since they are fairly large compared to gnats. You do have an air admitance valve under the kitchen sink and also under the bath sink. If they don't close they may be coming in there. The kitchen one is to the left of the sink in the corner.

Gnats are so tiny they can sneak in from just about anywhere though. Here's a sewer fly.

Thanks! These do not have noticeable "wings" like a fly. But they do seem to "float" about. When found in or around sink or in trash they appear to almost "hop". I'll try cleaning pipe and trap. Although I'd think the liquid fire would've killed them. A few just "floated" past as I type this! Aaargh!

From your later description, you're right. They don't sound like drain flies. Sounds more like gnats or fruit flies but then again those critters are attracted by the vinegar. Not sure now.

Grumpy's post shows a good picture of the drain flies and they do have defined wings.

If they hop could be fleas.

Get something like a custard dish, fill it with about an inch of apple cider vinegar and add a small amount of dishwashing detergent. Then cover the top with plastic wrap and and poke some holes in the plastic wrap with a round toothpick to allow the bugs to enter the dish and drown. Works for us!

Definitely not.fleas. They really look like what has been described as sewer flies. I just dont understand why they're not attracted to the apple cider vinegar. Or why the liquid fire didn't wipe em out. Must be some kindof mutated FL thing!

Post a pic of some. Preferably on a white background. Catch some on masking tape or something similar.

If they are what I'm thinking, you might want to go through all the cabinets and drawers. Look for old fruits and vegetables. Sometimes a potato falls out of the bag and rolls out of site.

That is precisely what they look like. I can't find any fruits, vegetables or anything that they are after tho. If I can manage to get a pic I'll post it
