Little Black Flies

I am having a bit of a problem with little black flies, which I think are fruit flies, however there is no food source in the house for them. It all started when we brought the house plants in for the winter. It has been 5 months now but these little buggers are persistent. We have put out fruit fly lures and have had limited success. Does anyone know what kind of flies these are, and how I can get rid of them. I was hoping the farther along into winter we got they would have dies off, but just the opposite, I probably catch 10 to 15 a day!!! I live in New Jersey if that helps narrow down the species of fly I am dealing with.
Thanks.

Greetings Joe..

If it is truly fruit flies, I've had the same problem... do this:
get a small clear cup or glass, fill it with about one inch of Apple Cider Vinegar. To this add about 2-3 drops of Liquid dish soap and stir.

Sit this out where the flies are. The next morning there should be dead flies in it. I change the mixture daily. Works better.

If you try this, let me know how it works for you.

Houseplants ...

... were the turning point?

If YB's fruit fly juice doesn't take effect (which it will, I use it too) then you probably have fungus gnats.

The potting soil may have enough spaghum moss in the mix to make a great habitat for them and they feed on small roots (can eventually kill young plants).

I've tried chemical soil treatments and they were only just okay as I didn't want to harm the plants. It might work for you. What I really liked were something called "Bug Stix". It is a sticky sheet on a stick that you put in the pot, it's the size of a bookmark, 1.5" x 6". Very shortly, no more fungus gnats laying eggs in the soil with the larvae consuming the roots ... more than just pesky flying things!

Fungus Gnats...Thank you!!!

Thank you for your suggestions, after reading these responses it sounds a lot more like the fungus gnats as these little buggers are all over the place and not limited to certain areas of the house, so I have ordered the Bug Stix (limited vendors for this product), and will give them a try.

Thanks Again, hopefully this will put an end to my situation.

Sure Thing

Here's a search page full of choices. The ones I used are Yellow rectangles on wood sticks about 6" x 2".

Here's where I originally got them:

Gnat Stix Insect Trap formerly known as "Bug Stix". Fungus gnats are those nasty little flies that breed in the damp soil of potted plants. ...

Joe ...

... Good luck with that and they'll be gone in a New York minute (or so ;) ), and if you have pets with long furry tails, it is best to put the Stix where those tails can't go!!!!! I had to, once I stopped laughing although miss cat didn't think it so funny. Bad Mommy! :)

fungus gnats

Definitely fungus gnats!! For the Yankees in the crowd of fungus gnat haters, fly paper works very well. One inch or so wrapped around a popsickle stick or garden twig, if you will..very easy and cheap. Also, when you re-pot your plants, or start seedlings, "sterilize" the soil easily by pre-wetting the soil with boiling water, cooling to body temp or cooler before planting.
