Why Do Shower Flies Appear?
The most common cause is organic buildup inside the drain.
Over time, substances such as:
- Hair
- Soap residue
- Body oils
- Dead skin cells
- Dirt and debris
can form a sticky layer inside pipes.
This damp environment becomes the perfect place for shower flies to lay eggs and multiply.
Other Causes
- Dirty drains
- Standing water
- Poor ventilation
- Small plumbing leaks
- Rarely used drains
Even if your bathroom looks spotless, the problem is often hidden inside the plumbing.
