# This Insect Often Lives in Our Bathrooms — Is It Dangerous, and Why Is It There?

Ever stepped into your bathroom and noticed a small, quick-moving insect scurrying along the floor or wall? You’re not alone. One of the most common (and often misunderstood) bathroom invaders is a silvery, slippery little bug known as the **silverfish**.

So what is this insect, **why is it in your bathroom**, and most importantly — **is it dangerous**? Let’s break it down.

## 🐜 Meet the Silverfish

The insect you’re likely spotting is called a **silverfish** (Lepisma saccharinum). It gets its name from its:

* Silvery-gray color
* Fish-like, wiggling movements
* Teardrop-shaped body
* Three long tail-like appendages at the rear

Silverfish are **nocturnal**, meaning they’re most active at night — which is why you often see them during a late-night bathroom visit.

## 🚿 Why Do Silverfish Love Bathrooms?

Silverfish thrive in **warm, damp, and dark** environments. That makes your bathroom — especially under the sink, behind the toilet, or in the shower area — the perfect home. Here’s why:

* **Humidity**: Bathrooms are typically more humid than other rooms, and silverfish need moisture to survive.
* **Shelter**: They hide in small cracks, behind baseboards, or in damp towels and paper products.
