Dark-winged fungus gnats

7519.      South East Kansas on Jan 22 2025. Found inside house. I do have some house plants be will find them one or two at a time never this many. But all these are dead? Found on the floor and window seal. Also notice little black ant or two in my bedroom tho there is never any drink or food in there, looks like the same tiny black ants commonly found in summer running a trail to the food they find in a kitchen trash can or a long counter tops. . Like. My house is very clean and kept nice. I live with me and a girl who super clean as well. My question is what are these flying ones as seen in pictures. And should I be concerned and or how to delete them. Arkansas City, KS. United States

 

Number 7519.    These appear to be dark-winged fungus gnats (Diptera: Sciaridae). The adult flies are harmless nuisance pests, but their larvae can damage tender plants, especially in greenhouse/indoor situations. These larvae usually are found in very damp/saturated soils having a high organic material content. If you have indoor plants, you should let the soil dry out as much as practical between waterings.
