Question
They are tiny and fuzzy, almost moth-like. I mostly see them in the bathroom, not near fruit or trash. The sink drain has a slow smell sometimes.
Pest Or Not answer
Fuzzy moth-like flies near a bathroom drain usually point to drain flies. The source is often organic film inside the drain, overflow, or wet plumbing gap.
