Thеу gо bу mаnу names including punkies, punkys, buffalo gnats, buffalo flies, eye gnats, black flies, hippelates flies, no-seeums оr јuѕt plain оld “nats”. Mоѕt black flies bite. Females nееd а blood meal іn order tо bесоmе fertile аnd оnсе ѕhе mates, wіll lay hundreds оf eggs. Thоugh ѕhе wіll lооk fоr moist damp areas оn whісh tо lay hеr brood, еасh species wіll tаkе advantage оf prime locations whісh саn vary frоm region tо region.

I am particularly interested in the little black flies. On two separate occasions, I found one or two (both times dead) in my bed in the morning when I made the bed. These had thin little wings, but I have never seen one of them fly. They usually move very slowly. The first place I saw one was in my bathroom sink, coming out of the overflow drain. This was several months ago. I sprayed with a bug and insect spray which I keep on hand, plugged up the overflow drain, and that seemed to take care of them… until last evening. I was in my recliner and I saw one on the chair arm, just sitting there looking at me. I swatted him. It was approximately 3/16″ of an inch long and the others were about the same size. If these are the same creatures that were biting me back in the spring and summer, the bite is awful. Apparently I am allergic to their bite. I made the mistake of scratching it, not knowing if it was a bite or what since I saw no sign of anything that could have bitten me, but within 5-10 minutes of scratching I had a bump on my arm the size of a large lima bean and the itching drove me crazy. I finally put clear finger nail polish on the bite, but it took about three weeks for that place to go away and it left a purple scar on my arm. I hate creepy crawly things in my house, especially in my bed…I freak out!!!!!!!! Any suggestions of getting rid of them permanently?

What you’re describing sounds more like Drain Flies. Also known as moth flies, this species of fly doesn’t bite. It typically lives in the drain lines of showers, tubs and sinks and can be active all year long.
Drain flies can be controlled via the various methods described in our article here:
Drain Flies: https://bugspray.com/drain-flies.html
I’d start by treating the drains with Survivors – especially if your home uses a septic tank waste water disposal system.
Survivors: https://www.bugspraycart.com/sanitizer/liquid/survivors
And if you start seeing more than 2-3 a week, get some of the PT-565 for space spraying any room where they’re active. 565 can be used as needed and will quickly kill off any flying around which is important because they’re usually the egg layers and you don’t want them roaming around the home.
PT-565: https://www.bugspraycart.com/insecticide/aerosol/pt-565-xlo
Another fly you might have is some kind of fungus gnat which can also thrive in drain lines. However, this gnat can also live in potted plants, garbage disposals and recycling areas. Details on how to control this pest can be found here:
Fungus Flies: https://bugspray.com/fungus_fly_control.html
In summary, the methods used for either of the two flies above will also take care of any biting flies or gnats you have in case it’s neither of the two I mentioned. The key with all flies is getting them where they’re nesting and using a space spray to control the adults roaming around.
