Silverfish can be difficult pests to eliminate completely, but there are some measures you can take to reduce their numbers and prevent them from returning:
Remove food sources: Silverfish feed on a variety of organic matter, including paper, cardboard, fabric, and food scraps. Keep your home clean and free of clutter, and store food in airtight containers.
Reduce humidity: Silverfish thrive in humid environments. Use a dehumidifier to keep the humidity in your home below 50%.
Seal cracks and crevices: Silverfish can enter your home through small cracks and crevices. Seal any gaps around windows, doors, and foundations.
Use traps: You can purchase silverfish traps or make your own by placing a piece of cardboard or newspaper in a shallow dish of water.
Use natural repellents: Some natural substances, such as cedar oil, cinnamon, and cloves, are said to repel silverfish.
Contact a pest control company: If you have a severe silverfish problem, you may need to contact a pest control company.
Additional tips: Wash bedding in hot water weekly, vacuum floors regularly, keep sinks and drains clean, and repair any leaks.
