Silverfish are small, wingless insects known for their silvery-grey color and sleek, tapered bodies. They move with a distinctive, quick, fish-like motion, earning them their name. While they don’t bite or spread disease, they’re classified as nuisance pests because of the damage they can do to paper, books, glue, clothing, and even dry food products.
These pests are common in Calgary homes and businesses, especially in damp, warm areas such as basements, bathrooms, kitchens, and laundry rooms. Silverfish thrive in environments with high humidity and limited air flow, making them particularly persistent in older buildings and places with moisture problems.
You may have a silverfish infestation if you notice:
Silvery, fast-moving insects in dark corners or near sinks and tubs
Small holes or notches on paper, wallpaper, and books
Yellowish stains or shed skins on floors or in cupboards
Nighttime activity—silverfish are nocturnal and often go unnoticed until the population grows
Here are a few ways to help prevent silverfish from taking up residence:
Use dehumidifiers in damp rooms
Store dry goods in airtight containers
Keep books and papers off the floor in basements or storage areas
Seal cracks and crevices where silverfish can hide
Fix plumbing leaks and improve airflow in bathrooms and kitchens
