I have a huge fungus gnat problem that feels like started overnight. I went out this morning and they are all over the soil. I just recently watered as temperatures are 80-90 degrees and the plants are getting full sun. I'm not sure which route to take to get rid of them, as the soil is currently still moist. Any suggestions as to the best way to get rid of the gnats? I have several veggies growing and just fertilized and watered yesterday. I'm a bit nervous to do a soil drench of any kind because of the already moist soil. Any suggestions??
