Fish moths, also known as silverfish, are tiny insects that love dark and damp places. They often hide in cupboards, bathrooms, and basements. While they don’t bite or spread diseases, they can damage books, clothes, and food. If you find these little pests in your home, don’t worry! Here are simple ways to get rid of fish moths in SA homes.

Moisture Control
Fish moths thrive in damp places, so reducing moisture in your home is key. Here are some easy ways to do that:
- Use a dehumidifier or air conditioner to keep humidity low. High moisture helps fish moths survive.
- Fix any leaks in your home, such as dripping taps, broken pipes, or roof leaks.
- Keep your bathrooms and kitchen well-ventilated by opening windows or using exhaust fans.
- Seal cracks and holes in walls and floors where moisture can collect.
If your home stays dry, fish moths will find it harder to survive. Learn more about controlling humidity at home.
Food Source Elimination
Fish moths love starchy food, paper, and fabric. To keep them away:
- Store food in sealed containers, especially flour, cereal, and sugar.
- Clean up crumbs and spills immediately to remove food sources.
- Keep old books, newspapers, and magazines in dry areas.
- Store clothes and blankets in airtight containers to protect them from damage.
By cutting off their food supply, fish moths will have fewer reasons to stay in your home. Check out more tips on pest-proofing your pantry.
Natural Repellents
Many people prefer natural ways to keep fish moths away. Some effective options include:
- Essential oils like cinnamon, peppermint, orange, and tea tree oil. Add a few drops to cotton balls and place them in cupboards and drawers.
- Cedar blocks or sachets in wardrobes and storage areas, as fish moths dislike the smell.
- Cloves and bay leaves in kitchen cabinets as natural deterrents.
Using these natural solutions will help keep your home smelling fresh while keeping pests away. Find more about natural pest repellents.
Decluttering and Cleaning
A clean home is less inviting to pests. Regular cleaning and decluttering help reduce fish moth populations. Try these simple steps:
- Declutter storage spaces, especially in damp areas like basements and attics.
- Vacuum carpets, cracks, and crevices regularly to remove eggs and hiding fish moths.
- Use bleach-based cleaners in bathrooms and kitchens to sanitize surfaces.
- Check second-hand books, clothes, and storage boxes before bringing them inside.
Keeping your home clean will help prevent fish moths from making it their home. For deep-cleaning tips, visit home maintenance guides.
How Fish Moths Get Into Homes
Fish moths sneak into homes through small cracks, open windows, and under doors. They are often carried in on second-hand items like books, furniture, and clothes. If your home is humid or has plenty of food sources, they will settle in quickly. Regular inspections and preventive measures will help keep them out.
Signs of a Fish Moth Infestation
Knowing the signs of a fish moth problem can help you act fast. Here’s what to look for:
- Small, silver-grey insects scurrying in dark corners.
- Tiny holes in clothes, books, and wallpaper.
- Yellowish stains or scales left behind by fish moths.
- Fine dust or debris near bookshelves and cupboards.
If you notice these signs, start taking action immediately to prevent an infestation.
DIY Fish Moth Traps
You can make simple fish moth traps at home to catch these pests. Here are a few easy ideas:
- Jar Trap: Place a piece of bread or a starchy item inside a glass jar. Wrap the outside of the jar with tape so fish moths can climb in, but they won’t be able to get out.
- Sticky Tape Trap: Place double-sided tape along baseboards and near cupboards. Fish moths will get stuck as they try to pass over it.
- Newspaper Trap: Roll up a damp newspaper and leave it overnight. In the morning, toss the newspaper in a sealed plastic bag and dispose of it.
These traps help catch fish moths before they spread further in your home.
How to Prevent Future Infestations
Once you’ve removed fish moths, follow these simple steps to keep them from coming back:
- Keep all storage areas dry and clutter-free.
- Use airtight containers for food, clothing, and important papers.
- Regularly vacuum and dust hidden corners and baseboards.
- Repair any cracks or holes in walls and flooring.
- Use natural repellents like essential oils or cedar blocks as a long-term solution.
By taking these precautions, you can keep your home fish moth-free.
