Silverfish and Firebrats Control Guide: How to Identify, Prevent, and Eliminate Infestations
What Are Silverfish and Firebrats?
Silverfish and firebrats are small, wingless insects known for their fish-like shape and quick, wiggling movements. Though harmless to humans, they are considered nuisance pests because they damage household materials like books, wallpaper, and fabric.
Both insects have long antennas, a tapered body, and three bristles extending from the rear. Adults grow to about 1 cm (0.4 inches).
Silverfish: Shiny silver or metallic body covered in scales.
Firebrats: Gray or brown with dark mottled markings and no metallic sheen.
These insects thrive in homes year-round, hiding in dark, humid environments.
Should You Be Concerned?
While silverfish and firebrats don’t bite or spread diseases, they can damage your property over time. They feed on starches, paper, glue, wallpaper paste, and natural fibers, leaving behind holes, stains, and yellowish marks on books, documents, and fabrics.
Because infestations grow slowly, spotting one often means the problem has existed for months or even years.
Common Signs of a Silverfish or Firebrat Infestation
You may have an infestation if you notice:
Small holes or feeding marks on paper, books, or wallpaper
Yellowish stains or shed skins near infested areas
Live insects in bathrooms, attics, basements, or storage boxes
Nighttime sightings near sinks, bathtubs, or humid areas
Silverfish are drawn to damp, cool areas (75–95% humidity), while firebrats prefer warmer spots such as attics, furnace rooms, and water heaters.
Where They Hide
Silverfish and firebrats often enter homes through books, cardboard boxes, furniture, or paper products. Once inside, they hide:
Behind baseboards and molding
In wall voids and attics
Around plumbing and sinks
Inside cupboards, drawers, and pantries
Near heat sources or damp areas
They are nocturnal, fast-moving, and can live for months without food.
Did You Know?
Silverfish and firebrats originally came from tropical climates but have adapted to Canadian homes by living in areas that are warm and humid. They often spread through infested paper, cardboard, or stored goods.
🧹 How to Get Rid of Silverfish and Firebrats
1. Clean and Dehumidify
Cleanliness and moisture control are the keys to preventing infestations.
Vacuum regularly — especially behind appliances, under sinks, and inside cupboards.
Clean storage areas, closets, and bookshelves often.
Keep countertops, drawers, and pantries free of crumbs and debris.
Fix leaky pipes, faucets, or condensation issues.
Use a dehumidifier in damp basements or bathrooms.
Ventilate bathrooms and kitchens properly.
2. Trap Silverfish and Firebrats Naturally
You can trap these pests using a simple glass jar trap:
Wrap the outside of a glass jar with masking tape for grip.
Place a piece of bread or starchy food inside as bait.
Set the trap overnight in infested areas.
The insects climb in but can’t crawl out of the smooth interior surface.
3. Use Safe and Effective Products
If cleaning and traps don’t solve the problem, you can use eco-friendly or approved insecticides:
Diatomaceous Earth (DE): A natural, non-toxic powder that dehydrates crawling insects. Apply along baseboards, under appliances, and in cracks.
Boric Acid Dust: Long-lasting and low in toxicity. Apply it in dry, hidden areas where it won’t be disturbed.
⚠️ Always read the product label and look for a Pest Control Product (PCP) number to ensure it’s approved by Health Canada. Follow all safety directions carefully.
If the infestation persists, consider hiring a professional pest control technician for a targeted treatment plan.
4. Long-Term Prevention Tips
Store books, paper, and clothes in sealed plastic bins.
Keep cardboard boxes off basement floors.
Reduce humidity in attics, bathrooms, and laundry rooms.
Seal cracks and crevices around baseboards, vents, and plumbing.
Avoid storing old newspapers or magazines in damp areas.
