Question 1

Are silverfish dangerous?

Accepted Answer

Silverfish are not dangerous to humans — they don't bite, sting, or transmit disease. However, they can cause significant property damage over time. They eat paper, bookbindings, photographs, wallpaper, clothing (especially natural fibers like cotton and linen), and foods high in starch and sugar. A long-term infestation can destroy books, documents, clothing, and wallpaper beyond repair.

Question 2

What attracts silverfish to my Indiana home?

Accepted Answer

Silverfish require two things: high humidity and starchy or cellulose-based food sources. In Indiana homes, they thrive in poorly ventilated bathrooms, basements, crawlspaces, attics, and areas where cardboard boxes or old books are stored. They're often introduced in cardboard shipping boxes and quickly spread to humid areas of the home. Silverfish can survive for a year without food, making them difficult to starve out without treatment.

Question 3

Why do I keep seeing silverfish in my bathroom?

Accepted Answer

Bathrooms maintain consistently high humidity — exactly what silverfish need. They hide in cracks near the tub, behind baseboards, under sinks, and inside wall voids near pipes. Seeing silverfish regularly in bathrooms strongly indicates a larger population behind the walls. A few visible silverfish represent the tip of a much larger hidden population.

Question 4

How do you treat silverfish?

Accepted Answer

Leadtech Pest Services treats silverfish with crack-and-crevice applications in harborage areas (bathrooms, basements, attics, wall voids), dust applications in voids and attic spaces where silverfish populations are concentrated, and perimeter sprays. Reducing moisture is equally critical — we advise on dehumidification, ventilation improvements, and storage modifications. Treatment is backed by the Leadtech Guarantee.

Question 5

Can silverfish come back after treatment?

Accepted Answer

Silverfish can reinfest if the underlying moisture conditions are not corrected. Treatment eliminates the current population, but without addressing humidity and harborage, new silverfish can re-establish. Leadtech Pest Services provides advice on dehumidification and structural moisture sources as part of the treatment. The Leadtech Guarantee covers free re-service if silverfish return between scheduled visits.
