Gnats in San Marcos: common questions
Are gnats common in San Marcos?
Escondido and San Marcos's warmer inland temperatures speed up fruit fly breeding cycles on countertop produce left out during the hotter months. If you're seeing these signs at your San Marcos home, an inspection confirms it fast.
How do I tell if I have fruit flies or fungus gnats in San Marcos?
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.
