I have a pot full of basil sitting on my window sill (clove, sweet, and lemon) next to a japanese eggplant plant (that seems to hate the full sun it claims to love). A few weeks ago, I noticed a sudden infestation of fruit flies (or at least that's what they look like), not many but all were around the lemon basil. The flies have been steadily increasing little-by-little (I've already got one of those water-soap-vinaigre jars sitting on the sill), but this morning, I woke up to find that there's an entire army of the darned things and they've migrated to the nearby plants (they've pretty much stuck with the lemon basil before) because there's so, so many.
So far, the flies have not flown anywhere, except for the ocassional one or two every few days. However, it makes me feel like I'm keeping a filthy home to have fruit flies (because I'm crazy). Can anyone please, please help with an explanation for my fruit flies problem? Is repotting my only option for getting rid of these critters??
