Raise your hand if you’ve ever walked into your bathroom early in the morning — still half-asleep, coffee in hand — only to be greeted by a swarm of tiny, fuzzy-winged flies hovering around your sink or drain.
No, they’re not fruit flies.
No, they’re not gnats.
They’re drain flies — also known as sewer flies or moth flies .
And yes.
They love your bathroom.
They love your shower drain.
They love your sink.
They love the damp, dark, moist places you didn’t even think about cleaning.
Let me tell you — I’ve been there.
I once had a tiny fly invasion that made my bathroom feel like a scene from a horror movie.
They weren’t just flying around — they were everywhere .
And I wasn’t about to let a swarm of winged weirdos take over my morning routine.
So I did what any sane, slightly obsessed person would do…
I researched, I cleaned, and I won .
Let’s explore how to get rid of drain flies for good — and why they’re probably coming from your drain.
🧠 What Are Drain Flies – And Why Are They in My Bathroom?
Drain flies are small, fuzzy insects that look like tiny moths — with broad wings, soft bodies, and a taste for organic sludge .
They’re not dangerous — but they are gross .
Here’s what they love:
Bathroom sink drains
Moisture and buildup attract them
Shower drains
Perfect breeding ground for eggs
Bathtub drains
Leftover water and soap scum
Toilet base
Sometimes they hide under the rim or in cracks
Wet corners
Floor cracks, under rugs, or near the shower curtain
And the worst part?
They don’t fly in from outside.
They hatched in your pipes .
These flies don’t come for your face.
They come for your drain gunk .
