Trapping silverfish effectively involves using simple DIY methods or commercial solutions that lure them into a container or onto a sticky surface from which they cannot escape. These nocturnal pests are attracted to starches, sugars, and damp environments, making them relatively easy to catch with the right setup.
Effective Silverfish Trapping Methods
Whether you prefer a homemade solution or a store-bought option, several methods can help you reduce silverfish populations in your home.
DIY Traps for Silverfish
Homemade traps are cost-effective and can be very efficient when placed correctly.
The Glass Jar Trap
One of the most effective and straightforward DIY silverfish traps utilizes a simple glass jar. To create this trap:
- Prepare the Jar: Simply wrap the outside of a clean glass jar with textured tape, such as medical tape, masking tape, or painter's tape. This textured surface provides a grip for silverfish to climb.
- Add Bait: Place a small amount of cereal, oats, flour, sugar, or any other starchy food item inside the jar. Silverfish are highly attracted to these substances.
- Placement: Position the jar in areas where you've noticed silverfish activity, such as bathrooms, kitchens, basements, or closets.
The silverfish will be drawn to the bait and easily climb up the textured tape on the outside. Once they drop inside, the plain, smooth glass walls will be too slippery for them to climb out, effectively trapping them.
The Damp Newspaper Trap
This method capitalizes on silverfish's attraction to damp, dark places.
- Prepare the Trap: Roll up an old newspaper and dampen it slightly with water. Secure it with a rubber band to keep it rolled.
- Placement: Place the damp newspaper roll in an infested area before bed.
- Disposal: In the morning, silverfish that have sought refuge in the damp paper can be disposed of by taking the entire roll outside and burning it, or by sealing it in a plastic bag and discarding it.
Commercial Trapping Solutions
For those who prefer ready-made options, commercial traps are also available.
- Sticky Traps: These flat, adhesive-covered cards are often pre-baited and designed to be placed along baseboards, under sinks, or in pantries. Silverfish walk across the sticky surface and become permanently stuck. They are discreet and effective for monitoring pest activity.
Choosing the Right Bait
Silverfish have a diverse diet, but they are particularly fond of starches and sugars.
- Starches: Cereals, oats, flour, pasta, pet food, paper (especially glue in book bindings or wallpaper).
- Sugars: Granulated sugar, molasses.
- Proteins: Dried meat.
Mixing different baits can sometimes increase a trap's effectiveness.
Optimal Trap Placement
Strategic placement is key to successful silverfish trapping. Focus on areas that provide the ideal conditions for these pests:
- Dark and Damp Areas: Bathrooms, kitchens, laundry rooms, basements, attics.
- Food Sources: Pantries, cabinets where dry goods are stored.
- Hidden Spots: Along baseboards, under appliances, inside closets, behind furniture.
- Entry Points: Near cracks or crevices in walls and floors.
Beyond Trapping: Prevention Tips
While trapping is an excellent method for reducing existing populations, long-term control also involves prevention.
- Reduce Moisture: Repair leaky pipes, use dehumidifiers in damp areas, and ensure proper ventilation in bathrooms and kitchens. Silverfish thrive in high humidity (75-97% relative humidity).
- Declutter: Remove old newspapers, magazines, cardboard boxes, and other potential hiding spots and food sources.
- Seal Food: Store dry goods like cereals, flour, and pet food in airtight containers.
- Seal Cracks: Seal cracks and crevices in walls, floors, and around pipes to eliminate entry points and hiding places.
- Vacuum Regularly: Frequent vacuuming can remove silverfish eggs and food debris.
- Inspect Deliveries: Always check packages, old books, and used furniture before bringing them into your home.
By combining effective trapping methods with proactive prevention strategies, you can significantly control and eventually eliminate silverfish infestations in your home.

Trap Comparison Table
Here's a quick comparison of common silverfish trap types:
| Trap Type | Description | Ideal Bait/Attractant | Best Placement |
|---|---|---|---|
| DIY Glass Jar Trap | Glass jar with textured tape on the outside, allowing silverfish to climb in but not escape the smooth interior. | Cereal, flour, sugar, pet food, starchy items | Dark, damp areas like bathrooms, kitchens, basements, closets |
| Damp Newspaper Trap | Rolled-up, slightly dampened newspaper that attracts silverfish seeking a dark, moist shelter. | Natural attraction to damp paper and darkness | Active silverfish areas, corners, along walls |
| Sticky Traps | Commercial adhesive cards, often pre-baited, that immobilize silverfish upon contact. | Often pre-baited; can be enhanced with starch or sugar | Along baseboards, under sinks, in pantries, near known activity |
