If you'd prefer not to kill the little guys, you can take any deep, clear-glass container (so you can watch it work--pretty cool). A jam jar or such works fine.
Take an ordinary piece of printer-type or school-type paper and twist it into a cone with a wide mouth and a tiny bottom hole (JUST big enough for a gnat to get in). You may need to fold or cut the paper per the size of your jar.
The cone should look like it goes about halfway down into the jar (too toward the bottom, and they could crawl back out; too high and they might find the opening). Tape the cone together to hold its shape.
Place a piece of a banana, a little wine (not too much liquid or they'll drown; you can drop a wad of TP, etc. in there first to soak it up)...anything sour-sweet works wonders...
Tape cone to glass, place it in an undisturbed area, and count by the hour (if you can keep track!)
When you're done, release the beasts (they should be ok for a couple days...they have food and moisture...unless they've only had pure alcohol). At that point, you can decide to reset (if they've been REALLY heavy), or just dump and rinse your jar and keep it with your cone for the inevitable next round...
Gnats are usually in a house because of old food/trash being in the house for too long, damp or wet areas (still water), and ripe fruit. First give the area a good cleaning of where the gnats are. Wipe down, throw away trash, and air out the target area. A good mixture to use for cleaning is apple cider vinegar and baking soda. This foams up pretty quick, so be careful. It is not harmful to external contact with skin, so that's a good thing. You can also "trap" gnats by placing a a mixture of vinegar and a tablespoon of Dawn dish detergent. This traps the gnats and kills them. This method is good to put next to any fruit you may have in the kitchen.
