🔍 What Are Those Little Black Bugs?
Most “little black bugs” in bathrooms fall into one of four categories:


Drain Flies
(aka sewer gnats)
Tiny moth-like insects (1–2 mm), fuzzy wings, often seen near sinks/showers

Fruit Flies
Slightly larger, red eyes, attracted to organic gunk in drains or damp towels

Booklice (Psocids)
Very small, soft-bodied, thrive in humid areas with mold or paper

Carpet Beetles (larvae)
Dark, oval-shaped, feed on organic debris like hair and skin flakes

📌 All are drawn to moisture, warmth, and organic buildup — not filth, but neglect of damp areas.
