6743.      Very small fly. Photo shot in macro mode. Found in washroom and kitchen during winter. Harmless, but is a nuisance, finding 5-6 of these everyday, even though i kill them. Not very difficult to kill it with bar hands. Milton, On. Canada

 

Number 6743.  This appears to be a dark-winged fungus gnat (Diptera: Sciaridae). Their larvae usually are found in very damp/wet soil high in organic matter content. If you have potted plants in your home, allowing the soil to dry out as much as practical between waterings should prevent any population buildup. Click here for some suggestions.
