I have a small fly that is in all of the soil of my house plants, how do I get rid of them??

I have seen these flies for a long time, they are what I have always called fruit flies although I'm not sure if that is what they really are. I notice them on fruit that is starting to spoil, like my bananas. I think they lay their eggs in the soil of my plants. Whenever I water them I notice them fly out of the dirt. It is a tiny, black fly. I had heard that adding some dish soap to the water that you use for your plants can get rid of some pests and so I tried it and it didn't seem to help any. This is a pest I have had to deal with for a long time but I figured there must be someone out there that has an answer to the problem. Help please! :) thanks

Sciarid flies, or Fungus gnats, try a web search. The control is this.Take all plants outside, clean all saucers and trays,spray with any general purpose garden insecticide, allow foliage to dry ,replace plants, repeat as necessary. Watering frequency has no effect on this pest which can often be encouraged when repotting with organic materials contained in some composts.
Reply:your soil may be too wet, and this may be attracting them. Depending on what kinds of plants you have, try not watering them so often and letting the soil dry out a little. Of course. some plants require wet soil, and this could harm them. I worked at a greenhouse, and we had sometimes had this problem. We would give them the chance to dry out, or repot them with more dry soil and less wet soil. Again, the repotting depends on what kind of plant and if the roots are small enought to repot in the same container with dry soil. As far as adding something to get rid of them, I am not sure if there is anything. You can always call a local greenhouse and check with them! God lck!
Reply:The reason you have these flies is because you soil is too wet these are like fruit flies but they are not the same but in the same family ..just let you soil dry out and only water once a week with the minimum water required to keep the plant alive then go out to your local hardware store and pick up a can of "Raid house and garden" and just before going to bed at night spray the heck out of the plant and soil this should take care of your fly problem once and for all..good luck
