How to get rid of gnats in San Diego County
"Gnats" in a San Diego home usually means one of three different insects: fungus gnats breeding in overwatered houseplant soil, fruit flies drawn to ripening produce, or drain flies breeding in the film lining a sink or shower drain. Figuring out which one you have determines whether the fix is in your plant pots, your fruit bowl, or your pipes.
What you're dealing with
Fungus gnats, fruit flies, and drain flies (also called moth flies) are the three species most often lumped together as household gnats in San Diego homes, each breeding in a different moist source.
How to get rid of gnats: step by step
- Let houseplant soil dry out between wateringsFungus gnat larvae need consistently wet soil, so cutting back watering breaks their breeding cycle within a couple weeks.
- Cover fruit and produce, or refrigerate itFruit flies lay eggs on exposed ripening or overripe produce, so moving it to the fridge or covering it removes the target.
- Scrub drains with a bottle brushDrain flies breed in the organic film lining pipes, which a splash of vinegar or bleach alone will not reach.
- Set out apple cider vinegar trapsA shallow dish of vinegar with a drop of dish soap catches adult fruit flies and fungus gnats fast.
- Empty and clean drip trays under potted plantsStanding water in saucers gives fungus gnats another place to breed even after the soil itself dries out.
When to call a pro
If gnats keep returning after the soil dries out, the fruit bowl is clear, and drains are scrubbed, the breeding source is likely somewhere less obvious, like a slow leak or a rarely used floor drain. General pest control service can trace and treat a source that DIY steps are not reaching. Call (858) 400-6561 for current pricing.
Check general pest cost, or read the signs of gnats first.

Common questions
How do I tell if I have fruit flies or fungus gnats in San Diego County?
Check where they gather. Fruit flies cluster around produce on the counter, while fungus gnats stay close to houseplant soil and fly up when it is disturbed.
Why do gnats keep coming back even after I clean the kitchen?
If the breeding source is drain film or overwatered soil, surface cleaning will not reach it. The larvae need that specific wet material removed or dried out.
Are gnats in my house a sign of a bigger problem?
Not usually. Most indoor gnat issues trace back to a houseplant, a piece of produce, or a drain, and clear up once that specific source is addressed.
