Gnat and fruit fly control for Denver, where a citywide composting mandate is changing what breeds near the trash.
Call (844) 924-1337Fungus gnats are usually the first sign of trouble in a Denver home with a serious houseplant habit, breeding in the consistently moist potting soil that a shorter outdoor growing season all but requires, since so much of Colorado's gardening simply moves indoors for a bigger share of the year. A second, newer source is set to add real pressure alongside it: Denver's composting rules expand in 2026, and once multifamily properties and food service businesses citywide have to start setting organic material aside for pickup rather than bagging it straight into the trash, that waste sitting on site becomes a breeding opportunity fruit flies and drain flies simply didn't have before.
Between a houseplant culture that keeps potting soil damp indoors much of the year and a citywide composting shift about to change how buildings store organic waste, Denver's gnat and fruit fly activity traces to two distinctly local, fairly recent causes rather than the produce aisles and dirty drains that drive it in most other places.

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, drains, and compost storage. 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.
