Bugs in Wisconsin?

Question

My wife and are moved into our current house last December, so this is our first end of summer/beginning of fall in the house.

We live in central Wisconsin and the past week or so have noticed several gnat-like bugs in our upstairs bathroom.
The bugs are nearly always dead and for the most part are in the bathroom sink and sometimes the tub. Generally around six to 10 dead when I wake up in the morning.

The bathroom is clean and they don’t appear to be attracted to waste (i.e. garbage can and toilet brush). The live ones can fly, but appear to be near death or disinterested as they usually don’t fuss as you kill them.

Also, my wife and I have found no evidence of them spreading to any other rooms or parts of the house. The bathroom has a ventilation fan that goes through the attic, so I belie they may be entering the bathroom via the attic and fan.

We have had some drastic temperature changes in the past week, so I am hoping it is a species whose life cycle is ending sim

Answer 1

Put the plug in your bathtub drain and the bugs will go away. LOL!! They come from the sewer system and fly around looking for dead things to eat. We get them here in Missouri, too, and keep the plugs in the bathtub drain to keep them in check. Sometimes they come from the laundry room drains too. You might want to check there.

Answer 2

They are reproducing in the trap. Just pour PineSol or other oil type cleaner into the trap......1/2 cup at least.....put in the stopper before you leave for a few hours. Come home, unplug and run water down the drain. Gone.

Answer 3

We've been bothered by them this year also in IL, due mostly to all the rain we had. Bathroom sounds logical, because they like water.

Answer 4

Sounds like a haunting
