The Q&A Archives: nats flying over lawn

Question: What causes swarms of nats flying all over the lawn and how can I get rid of them. I can't even walk on my lawn without getting the nats or small fleas all over me. I live in Orange County Ca.


Answer: What you describe sound like fungus gnats. They are living and breeding in decomposing organic matter at the soil surface. They thrive in moist places and when you walk on the lawn you disturb them and they fly up. They do not feed on the lawn and they won't bite you. But, if they're bothersome, you can use an insecticide on your lawn to kill them. Bayer Advanced? Complete Insect Killer For Soil & Turf is one of the lawn treatments you can find in your local garden center.
