How to Use Old Newspapers to Get Rid of Silverfish Naturally

As the weather turns colder and more humid, you may find silverfish making an appearance in your home, seeking warmth and shelter.

While they pose no threat to humans, these pests can cause damage to items like books, papers, and wallpaper. So, what's the best way to quickly get rid of them without resorting to chemicals?

Experts in entomology have shared an innovative and cost-effective strategy to tackle these common indoor pests by utilizing their feeding habits and repurposing your old newspapers.

Why Old Newspapers Are Effective Against Silverfish

Entomologists suggest that a rolled-up newspaper can effectively trap and remove silverfish, known for their tendency to damage various materials and contaminate food. But how does this natural pest control method actually function?

"Silverfish thrive in moist, warm environments, favoring humidity levels above 75% and temperatures around 80°F," explains Dr. Tracy Ellis, a recognized entomologist at FarmSense. "By placing a dampened, rolled-up newspaper in these warm, humid spots, you provide both a refuge and a food source for them.

"Silverfish eat the cellulose fibers in the paper, breaking them down using specialized enzymes in their gut."

Once the silverfish have settled in, you can simply dispose of the newspaper.

"It's an easy way to eliminate them all at once," concurs Tony King, a pest control expert and founder of The Pied Piper Pest Control. "This is a tried-and-true method that can effectively reduce their numbers if you notice signs of silverfish in your space."

Additionally, Dr. Ellis notes that silverfish emit aggregation pheromones, which signal to others that a location is suitable for gathering, meaning where one goes, others follow.

However, if you're facing a larger infestation, you should also watch for any indications that it's time to contact pest control, like those at Orkin, who can effectively manage the problem.

How to Implement the Newspaper Method for Silverfish

"To execute this technique effectively, take several sheets of newspaper, loosely roll them into a tube, and moisten them just enough so that they are damp but not dripping wet," advises Tony, suggesting the use of a spray bottle, like the Great Value All Purpose Plastic Spray Bottle available at Walmart.

"Position the roll in areas where you've detected silverfish activity, such as alongside baseboards, under sinks, or in bathrooms, as these are common hiding spots for pests."

After about a week, you can dispose of the newspaper. Tony recommends burning it, while Tracy suggests sealing it in a bag and freezing it before throwing it away in an outdoor trash bin.

This preventive measure can help stop this common winter pest from returning by ensuring they don't make their way back into your home.

What Are the Limitations of This Method?

Ultimately, Tony states that the primary limitation of this method is that it primarily serves as a trap-and-dispose technique, rather than a comprehensive eradication strategy.

"This method won't eliminate a large infestation or their eggs, so silverfish can continue to appear if the right conditions persist. It also necessitates regular monitoring and replacing of the traps, which can be inconvenient for some people."

Furthermore, Daniel Baldwin, a board-certified entomologist at Hawx Pest Control, emphasizes the importance of ensuring that silverfish have no reason to inhabit your space. If you do use this newspaper method, it's best to combine it with other proven pest control techniques.

"Newspaper roll traps can be effectively paired with glue boards or sticky traps [like the Catchmaster Max-Catch Mouse & Insect Glue Trap available at Amazon] positioned along walls, baseboards, and behind furniture for enhanced monitoring," Tracy suggests.

Additionally, Tony recommends including products that actively kill silverfish as part of a comprehensive pest management plan.

For instance, he recommends the Dekko Silverfish Paks available at Walmart, which work continuously for several weeks, or Safer Home Diatomaceous Earth available at Amazon.

"This product can be lightly sprinkled in crevices, behind appliances, and along baseboards to dehydrate and kill silverfish," he explains. "Combining these products with the newspaper method will significantly improve long-term control of silverfish."

"Overall, the newspaper method is a useful tool for identifying primary hiding spots," Tracy notes. "Effective control requires additional measures like reducing moisture, sealing entry points, and removing paper-based food sources." Therefore, using a dehumidifier can be surprisingly beneficial for getting rid of silverfish.
