I have about 30 potted plants. Some were outdoors for the summer and are now indoors. There are an increasing number of gnats around the soil and flying around the apartment. I have two trays with vinegar and sugar which helps to attract and catch a few, but not enough. Once in a while I will spray bug killer over the plants, but is probably the wrong kind. How do I better control the spread of gnats? Or do I need to replace all the soil?
