personally i use pyrethem...i think thats how its spelled, neem is also good or insecticidal soap, the only problem with the soap is that you pretty much have to spray the bugs directly to kill them but what the hell right. for my room i had fungus knats so i sprayd pyrethem then waited about 2 days and let a can of lady bugs in there, the ladys eat the larve mostly, what i do is put a few plastic cups throughout the room with a paper towel soaked in 7up and some apple slices in another, you can tell when the bugs are hungry because they will end up in other parts of the house, i like using the bugs because they keep a better eye on the plants than i ever could, all day they cruise the crops eating
