How to Get Rid of Silverfish in Bathroom

Silverfish are common pests that thrive in damp, humid environments, making bathrooms an ideal location for them to inhabit. These small, wingless insects are not only unsightly but can also cause damage to books, paper, fabrics, and even bathroom products. Getting rid of silverfish in your bathroom can seem challenging, but with the right knowledge and strategies, it is entirely possible.

This guide on how to get rid of silverfish in bathroom will help you understand what attracts silverfish and provide practical steps to eliminate them and prevent future infestations.

What Are the Causes of Silverfish Infestations?

Silverfish infestations in bathrooms are more common than you may think. These tiny insects thrive in dark, damp environments, making your bathroom the perfect breeding ground. Some of the leading causes of silverfish infestations include:

  • Moisture: Silverfish require a moist environment to survive, and bathrooms typically have high humidity due to showering and bathing.
  • Food Sources: Silverfish feed on starches and sugars found in book bindings, wallpaper paste, shampoo residue, and even toothpaste. If these items are present in your bathroom, they can attract silverfish.
  • Clutter: Clutter provides shelter for silverfish to hide in and lay their eggs, making it easier for them to establish a colony in your bathroom.
  • Plumbing Leaks: Leaking pipes or faucets can create the perfect environment for silverfish to thrive. The constant moisture allows them to survive and reproduce.
  • Poor ventilation in bathrooms can contribute to high humidity levels, which are ideal conditions for silverfish.

What Will You Need?

  • Sealant: Seal any cracks or crevices in your bathroom to prevent silverfish from entering.
  • Dehumidifier: Use a dehumidifier to reduce humidity levels in your bathroom and make it less appealing for silverfish.
  • Boric Acid: Sprinkle boric acid powder in areas where silverfish are commonly found, such as under sinks and behind toilets. This natural insecticide can help eliminate silverfish.
  • Cedar Shavings or Essential Oils: Silverfish dislike the smell of cedar, so placing cedar shavings or a few drops of cedar essential oil near entry points can deter them from entering your bathroom.
  • Cleaning Supplies: Keep your bathroom clean and dry to prevent silverfish from finding sources of food. Regularly wipe down surfaces and fix any leaks that may be contributing to excess moisture.
  • Sealing Cracks and Openings: Silverfish can enter through small cracks and openings, so sealing these areas can help prevent them from entering your bathroom.
  • Dehumidifier: If you live in a humid climate or have a particularly damp bathroom, using a dehumidifier can help reduce the overall humidity levels and make it less desirable for silverfish.
  • Professional Pest Control: If the above methods are ineffective, it may be best to consult a professional pest control service. They can identify the source of the silverfish infestation and provide targeted treatments to eliminate them from your bathroom.

8 Easy Steps on How to Get Rid of Silverfish in Bathroom

Step 1: Identify the Infested Areas 

The first step in tackling a silverfish problem is to identify the specific areas where they are most active. Silverfish are nocturnal pests, so you might notice their presence during the night or in dark, undisturbed corners. Look closely around bathroom cabinets, under sinks, behind the toilet, or along baseboards where they tend to hide. Be sure to inspect small crevices, as silverfish often squeeze into tight spaces. Additionally, check for signs of their activity, such as yellow stains, droppings, or damage to paper products, fabrics, and other materials they feed on. Identifying these areas will help you focus your efforts and apply targeted solutions effectively.

Step 2: Eliminate Food Sources

Silverfish are attracted to starchy materials and high-protein substances, such as paper, cardboard, fabrics, and even wallpaper glue. To deter them, remove or securely store items like books, magazines, clothing, and food in airtight containers. Regularly clean areas prone to infestation, such as closets, storage spaces, and pantries, to eliminate debris and crumbs. Reducing their access to these food sources is a critical step in controlling and preventing silverfish infestations.

Step 3: Minimize Moisture 

Silverfish thrive in damp and humid environments, making moisture control an essential prevention component. Start by addressing any leaks or sources of excess moisture in your home, such as dripping pipes, faulty faucets, or areas with poor ventilation. Use dehumidifiers to reduce humidity levels, especially in basements, bathrooms, or laundry rooms where moisture tends to accumulate. Proper air circulation is also critical—ensure that rooms are well-ventilated by using exhaust fans or opening windows when weather permits. Regularly inspect and clean areas prone to dampness, such as under sinks, around bathtubs, and behind appliances, to prevent water buildup. Maintaining a dry environment creates an inhospitable habitat for silverfish, significantly minimizing the risk of infestation.

Step 4: Use Natural Repellents

To deter silverfish naturally, you can use common household items as repellents. Sprinkle diatomaceous earth in areas where silverfish are likely to hide, such as cracks, crevices, and along baseboards. Cedarwood chips or sachets filled with cloves, cinnamon sticks, or dried lavender can also act as effective deterrents due to their strong scents. These solutions provide an eco-friendly way to prevent silverfish without using chemical pesticides, while also being safe for most homes.

Step 5: Check for Moisture

Silverfish are highly attracted to moisture and thrive in damp environments. Begin by inspecting your home for any signs of excess humidity, such as condensation on windows, damp walls, or a musty smell, especially in bathrooms, basements, kitchens, and laundry rooms. To reduce moisture levels, consider using a dehumidifier to maintain indoor humidity below 50%, which can help discourage silverfish infestations. Additionally, fix leaky faucets, pipes, or roof leaks promptly to eliminate potential sources of moisture. Proper ventilation is also essential, so ensure exhaust fans are functioning correctly in high-moisture areas and aim to increase airflow with open windows or vents where possible.

Step 6: Regular Cleaning and Decluttering

Regular cleaning and decluttering are vital components in controlling and preventing silverfish infestations. Begin by thoroughly vacuuming areas where silverfish are likely to hide, such as along baseboards, behind furniture, and in closets. Pay close attention to corners, crevices, and gaps that can be hiding spots. Decluttering is equally essential, as piles of paper, old books, and cardboard boxes provide ideal feeding grounds and nesting areas for silverfish. Remove unnecessary items, store important documents in sealed plastic containers, and replace damp or decaying materials. Maintaining a clean and organized space not only discourages silverfish but also makes it easier to detect and address any potential infestations early, ensuring a healthier living environment.

Step 7: Professional Pest Control

If a silverfish infestation persists despite your best efforts, it may be time to consult a professional pest control service. Pest control experts have the necessary training, tools, and products to effectively eliminate silverfish and prevent their return. They can assess the severity of the infestation, identify hidden breeding grounds, and implement targeted treatments that are safe for your home and family. Professionals also provide valuable advice on long-term silverfish prevention, such as managing humidity levels, sealing entry points, and maintaining clean spaces. Relying on expert help ensures a thorough resolution to the problem while giving you peace of mind.

Step 8: Keep a Clean and Tidy Home

Keeping a clean and tidy home is essential for preventing silverfish infestations. These pests are attracted to cluttered areas where they can hide and breed easily. By decluttering your living space regularly, you eliminate potential hiding spots for silverfish, making it harder for them to survive in your home.

In addition, keeping your home clean helps to reduce the presence of food sources that attract silverfish. These pests are commonly found in areas with high moisture and food sources such as crumbs, paper products, and starchy items.

Following a regular cleaning routine can minimize the chances of having silverfish infestations in your home.

5 Things You Should Avoid

  1. Ignoring Moisture Issues 

  Silverfish thrive in moist environments, so failing to address leaks, condensation, or high humidity levels will only encourage their presence. Always fix plumbing issues and ensure your bathroom is well-ventilated.
