Adult fungus gnats live for just seven to ten days, but the female can lay up to 200 eggs in the cracks and crevices of moist soil, so populations grow quickly. Photo Courtesy of Summit Responsible Solutions
They flit across your face, hover near your houseplants, or gather by the window. Fortunately, these fungus gnat insects are more annoying to us than harmful to our plants.
This pest finds its way into our homes on plants added to our indoor houseplant collection or those moved inside after a summer outdoors. Some may enter on organically rich, nonpasteurized soil.
