Home Remedy to Kill Silverfish

Killing silverfish requires a combination of active and passive measures designed to kill the current generation of silverfish while also preventing their eggs from hatching. This process is not difficult to carry out, but does take a bit of time and skill.

Fortunately, with the right knowledge, you'll be equipped to kill the silverfish that are infesting your home or office with no trouble at all.

Passive Measures

Most home remedy actions that can be taken against silverfish involve making your home as unwelcoming to them as possible. For starters, reduce the humidity in your home by installing a dehumidifier, and turn your heat either to above 80 degrees Fahrenheit, or to below 60 degrees Fahrenheit. Silverfish can only survive in temperatures that are between 60 and 80 degrees Fahrenheit with a high humidity, so by changing their environment from friendly to hostile, you can quickly kill any silverfish in your house.

Keep anything that they can use as a food source locked tightly away. Crumbs, paper, book glue and wallpaper glue are all potential feasts for a silverfish, so keep your books high on a shelf that is key clean and dust free, sweep and mop your floors regularly, and make sure that your wallpaper doesn't have cracks or peeling corners that a silverfish could use to get food.

Finally, make sure that you plug up as many entry points into your home as possible. Silverfish can use cracks in doors and windows to enter a home, as well as cracks in brickwork, around pipes and even the cracks between the floor and baseboards to hide and move from room to room.

Active Measures

Once your house has been rendered inhospitable toward silverfish, you can focus your attack on killing and driving out any stragglers that may have survived. A popular home remedy for keeping silverfish out of your home is to place whole cloves near entrances that they might use. Silverfish don't like the smell of cloves, and this will help keep them away from your home. You can also use spread boric acid around likely entry points, which they will carry back to their nest and will kill their colony. Boric acid is a natural insecticide, and is great for applying to dark closets, corners or other areas that may be hard to clean or reach.
