The important factors are not simply whether a room looks clean, but whether the insect can find a suitable combination of shelter, food, and environmental conditions.
Access to food
Silverfish feed on a range of materials containing starches,
sugars, and other carbohydrates.
Potential food sources include paper, book bindings, cardboard, glue, certain fabrics, and crumbs or other organic debris.
Some species can also feed on dried plant materials and stored products.
This broad diet helps explain why silverfish may appear in several different areas of the same building.
They are not limited to bathrooms, despite the common association between these insects and damp rooms.
3. Does Finding a Silverfish Mean Your House Is Dirty?
One of the most persistent misconceptions about silverfish is that their presence proves a home is dirty.
That is not accurate.
Silverfish can occur in clean, well-maintained homes because they are attracted to environmental conditions and accessible materials, not simply to visible dirt.
