Gnat and fruit fly control for Fontana, distinct from the coordinated Mediterranean fruit fly quarantine activity seen elsewhere in California.
Call (844) 924-1337Southern California's Inland Empire, where Fontana sits, is a long way from the Bay Area cities such as San Jose and Fremont that California placed under active Mediterranean fruit fly quarantine in 2024 and 2025. That invasive fly has been a genuine statewide concern since a major eradication campaign in 1981, capable of threatening hundreds of fruit and vegetable crops and triggering sterile fly releases plus organic pesticide treatment whenever it resurfaces, but the response has stayed concentrated up north rather than reaching Fontana.
Fontana homeowners are far more likely to run into the everyday version of the problem, fruit flies breeding in ripening produce, or fungus gnats in an overwatered houseplant's soil. Tracking down that specific indoor source is usually the fastest way to clear it up. Call (844) 924-1337 to discuss pest control help in Fontana and check service availability.

Finding and eliminating the breeding source, whether that's overripe produce, a drain, or the garbage disposal, matters more than swatting the flies you can see. Traps can help reduce the adult population while you address the source, but a recurring problem often means the source hasn't fully been found yet.
Note where the flies gather, including any activity around plant containers and stored produce. Describe whether the problem is limited to one area or appears in several places, and what cleaning or watering changes you have already tried. That record helps focus the search for the source without assuming every small fly is a fruit fly.
Explain which area you cleaned, whether sightings decreased, and where flies appeared again. Mention whether activity stayed near the original spot or shifted elsewhere. Ask whether another breeding source needs checking before repeating the same approach; fewer visible adults alone does not establish that the source has been addressed.
Fruit flies and fungus gnats have different sources, produce and drains for fruit flies, overwatered houseplant soil for gnats, so treating both effectively means identifying which you actually have. Identifying which flies are present helps focus the inspection and treatment on the correct breeding source.
