Spending time in your backyard should be relaxing — but nothing ruins a warm evening on the patio faster than a cloud of tiny gnats buzzing around your face. These outdoor pests love Southern California’s warm climate, and in Rialto and Fontana, they can show up almost year-round.
At TruPest Solutions, we know how frustrating outdoor gnats can be for homeowners. Let’s talk about where they come from, why you don’t want them hanging around your yard, and the best ways to keep them away.
Where Do Outdoor Gnats Come From?
Gnats are drawn to damp, organic materials and places where they can breed easily. Around Rialto and Fontana yards, we often find them in:
Overwatered lawns and gardens – fungus gnats thrive in soil that stays wet for too long.
Near trash cans and compost bins – decaying organic matter is a favorite food source.
Around drains, puddles, or standing water – moisture attracts gnats quickly.
Damp mulch beds and shaded soil – these areas provide shelter and breeding grounds.
Because our climate is warm, these conditions can lead to gnat problems any season of the year.
Why Outdoor Gnats Are a Problem
While gnats outside may not seem as bad as having them in your kitchen, they can still create plenty of issues:
They make outdoor spaces uncomfortable – no one wants to swat bugs while relaxing outside.
They multiply quickly – a few gnats in damp soil can turn into a swarm in days.
They damage plants – fungus gnats feed on roots and fungus in the soil, weakening grass and garden plants.
They attract other pests – moisture and decay that draw gnats can also attract flies, mosquitoes, and more.
How to Get Rid of Gnats Outside
Controlling gnats outdoors is all about removing the conditions that attract them and adding long-term protection.
DIY Prevention for Outdoor Gnats
Avoid overwatering lawns and let soil dry between watering cycles.
Keep trash cans closed tightly and clean them regularly.
Remove standing water from buckets, plant saucers, and clogged gutters.
Turn compost regularly so it doesn’t become too damp and smelly.
Use gravel or well-draining mulch instead of heavy, damp mulch beds.
