How to spot them
Teardrop-shaped, silvery insects that wriggle like fish when disturbed — in bathtubs, closets, and storage boxes. Often you find the damage first: yellowed pages, chewed cardboard, small holes in stored linens.
Why they show up in the Central Valley
Silverfish chase humidity and starch. Bathrooms, garages, and packed storage closets give them both — paper, book bindings, cardboard, and photo boxes are all on the menu. They can live for months between meals, so they outlast waiting games.
What you can do right now
Store keepsakes in sealed plastic bins instead of cardboard, run the bathroom fan after showers, and cycle through stored boxes yearly so nothing sits undisturbed for a decade.
How Cornerstone handles it
Routine treatment of the cracks, closets, and moisture zones they travel keeps populations from ever building. Silverfish are part of standard coverage on every plan.
