Currently, my apartment is being attacked by fungus gnats which are little black flies that fly around everywhere, and land in my food and drink. Fungus gnats can be very bad for your plants, but there also incredibly irritating. The most important thing you need to do is cut back on the watering. They are usually caused by having soil that is too moist. Check the soil to see which plants they are coming from.
I was going to put something in the soil to see if that would cut down on the fungus gnats. However, I am always scared that putting something in the soil could damage my plants, so for the time being, I’m just going to cut back on the watering, and see how things go. So far, cutting back on the watering does seem to help with the fungus gnat problem. If anyone out there has any other suggestions, please let me know. As I say above, I have read that fungus gnats can be very bad for your plants, but quite frankly, I’ve been living with them for quite a while now, and nothing terrible has happened to my plants yet. At the same time, I certainly wish I could find a solution to this problem that would not entail putting chemicals in the soil.
