Let lawns and garden beds dry thoroughly between watering to cut down on the moisture-rich environment favored by gnats, suggests Taylor. Eliminate decaying organic matter such as grass clippings, dead plants and leaves, which are a common place for gnats to lay their eggs.

More tips for keeping unnecessary moisture at a minimum in an outdoor space include raking and overturning mulch from time to time to allow moldy or wet layers to dry, watering in the morning to avoid overnight fungus growth, and checking gutters and drainage areas for standing water, states Julie Day of Today's Homeowner.
