small flies around thyme sprouts?
I am sprouting thyme from seed, and there seems to be small flies (much smaller than house flies) walking and flying around the soil and sprouts. There are other plants around like basil and cilantro. These are indoors (in the basement) being lit by florescent lights.
Is there something I can use to kill these flies? They seem to be multiplying. The thyme will eventually be used in food, so I don't want to do anything poisonous.
