What should I do if I find a tiny black bug with wings in my house?

If you find a tiny black bug with wings in your house, it is likely a common household pest like a fruit fly or a fungus gnat. You can try to eliminate them by cleaning up any food or moisture sources that may be attracting them, sealing up cracks and crevices where they may be entering, and using traps or insecticides if necessary. If the problem persists, consider contacting a pest control professional for assistance.
