Where are you most likely to find fungus gnats inside a home?

Fungus gnats are primarily associated with damp soil, making potted plants the most likely location to find them inside a home. These pests thrive in environments where organic material is present and moisture is retained, particularly in the soil of houseplants. The larvae of fungus gnats feed on the organic matter in the soil and can also damage plant roots, which can lead to further plant health issues.

While it is possible to encounter fungus gnats in other areas of the house, like kitchens (where food scraps could create breeding sites), basements (which might have dampness), or bathrooms (with potential moisture), their strongest association remains with the moist, organic-rich soil of potted plants. This habitat provides optimal conditions for their lifecycle, thereby leading to an increased presence compared to other areas in the home.
