Ah. I should have posted this on another board. Will I get in trouble if i post this message in the Pests & Diseases forum too?

They sound like fungus gnats to me. They are controlled with a BT listed for fungus gnats on the label. The larvae are eating the plant roots so they should be controlled. Al

the best way .. indoors.. is to insure you start with sterilized soil .... how to.. at the link ... i suggest you do it.. before the house gets closed up for winter ...

then use the sterilized soil to repot all the plants coming into the house ...

and learn proper watering .... letting your plants nearly dry between waterings... watering is not a science of scheduling.. it is an art ... you must check the soil with your finger ...and only water when dry .... these bugs... thrive in overly saturated soil ... we can not tell you when to water.. because it is all intertwined with your house.. your furnace/AC ... your ambient humidity .. etc ...

you become a green thumb by constant insertion of your finger into the soil ... for any reason you can come up with .. lol

as they say.. an ounce of prevention.. is worth a pound of cure ....

good luck

Here is a link that might be useful: in your oven or microwave

Thanks to all.

You can also cover the top of your soil with 1/4 inch pea gravel, we did this a lot at the nursery that I worked at. The problem with this is that you can not visually tell when the soil is dry.
