10 Tips on How to Stop Silverfish for Good

Silverfish are small, silver-grey insect pests that, despite their name, are not actually fish. Instead, they get their name due to their quick, fish-like movements, silver colour, and love of moist environments.

Silverfish can wreak havoc, causing significant damage to your home if left alone. Their favourite things to destroy are paper, wallpaper, and starchy materials.

While they are an unwanted nuisance, the good news is that you can prevent and control silverfish infestations yourself. Here are 10 practical tips to stop silverfish fast and keep your home pest-free.

#1 Reduce Humidity

Silverfish thrive in moist conditions. This makes keeping your home dry essential at all times.

We recommend ensuring that all bathrooms and kitchens are properly ventilated. This may involve installing ventilation fans and ensuring general spaces in the house are ventilated naturally.

You may also consider using dehumidifiers in damp areas like basements and attics. Don't forget to address any leaks promptly to reduce moisture levels.

#2 Maintain a Regular Cleaning Routine

Silverfish are attracted to food debris and dust, especially in more hidden spaces.

This means maintaining a clean environment essential as it makes it harder for silverfish to find food and shelter.

We recommend regularly vacuuming and dusting your home thoroughly. Focus on hard-to-reach places such as areas behind furniture, inside closets and under kitchen and utility appliances. 

#3 Store Starchy Items Properly

Silverfish are attracted to starchy materials such as books, papers and fabrics.

It's important to store such items in airtight containers or plastic bins with tight-fitting lids. This prevents silverfish from eating their preferred food and should encourage them to go elsewhere.

#4 Seal Cracks and Crevices

Inspect your home for entry points, such as gaps around windows, doors, and pipes which could be used by silverfish or similar pests.

We recommend using caulk or other sealants to block these openings. Sealing cracks not only prevents silverfish from entering your home but also reduces hiding places.

#5 Address Damp Areas

Regularly check for dampness in less touched places such as basements, attics, ceilings and under sinks.

Keeping these spaces dry discourages silverfish from settling. Conduct regular maintenance to fix or prevent leaks and install moisture absorbers to reduce dampness. Don't be afraid to call professionals in if you have concerns.

#6 Use Natural Repellents

Essential oils such as cedar, lavender, and citrus may also act as natural deterrents for silverfish.

Spray these oils in areas where silverfish are active, such as corners, baseboards, and storage spaces. Their strong scents are often believed to repel these pests effectively.

#7 Apply Diatomaceous Earth

Diatomaceous earth is a natural powder that provides a safe and effective way to kill silverfish.

Sprinkle diatomaceous earth in areas where silverfish are likely to travel, such as near baseboards and cracks. The powder dehydrates silverfish on contact, eliminating them without harmful chemicals.

#8 Set Homemade Traps

Homemade silverfish traps can help control silverfish populations effectively.

A simple trap involves placing rough masking tape on the outside of a glass jar. Silverfish are able to climb the tape to enter the jar but cannot climb back out due to its smooth interior.

This method is an easy, chemical-free solution and you can use something simple like bread as bait inside the jar.

#9 Use Insecticides as a Last Resort

If natural methods don't work, you may wish to consider chemical insecticides designed for silverfish.

These sprays and powders should be applied to cracks, crevices, and other hiding spots where silverfish are likely to live.

Always follow the manufacturer's instructions to ensure safe and effective use.

#10 Clean and Repair After Infestations

After removing a silverfish infestation, remember to thoroughly clean the infested areas. This includes removing any eggs and other debris.

We recommend using a vacuum or steam cleaner to clean cracks and crevices.

Repair damaged wallpaper, books and other items to restore your home and prevent further infestations.

Final Thoughts

Stopping silverfish yourself requires a combination of preventative measures and targeted control techniques.

Focus on reducing humidity, maintaining cleanliness and sealing entry points. This will give you the best chance of protecting your home from these pests.

If the infestation persists or is difficult to tackle yourself then seek professional help. They should be able to ensure a long-term solution.
