FAQs About Silverfish in Ontario

Can’t find your answer? Our team is always happy to help.

Where are silverfish commonly found in Ontario homes?
Silverfish are often found in basements, bathrooms, storage areas, and other dark spaces with higher humidity.
They may feed on starches and cellulose found in paper, book bindings, cardboard, glue, and some fabrics or stored materials.
Look for live insects, shed skins, or irregular surface damage on paper and stored items, especially in dark, humid areas.
Silverfish prefer humid conditions, but they may still persist indoors if they have suitable shelter and food. Reducing excess moisture can help.
Keep storage areas dry, use sealed containers for vulnerable materials, and avoid storing paper or cardboard directly against damp walls or floors.
Technicians inspect likely harbourage, assess moisture and access conditions, and recommend targeted control and prevention steps for the affected rooms.
