Does Bleach Kill Silverfish?

Silverfish (Lepisma saccharinum) are small, primitive, wingless insects that can be a nuisance in homes. They are known for their destructive feeding habits and can cause significant damage to household items. Despite their small size, these nocturnal insects can be quite elusive and difficult to control. This brings us to the question: does bleach kill silverfish?

What are Silverfish?

Silverfish are typically 13–25 mm long and have a silvery light grey color. They get their name from their fish-like movements. These insects thrive in dark, moist environments with humidity levels between 75 and 95 percent. They can be found under rocks, leaf mold, and tree bark in their natural habitat. In residential buildings, common silverfish habitats include basements, bathrooms, kitchens, and attics.

Why Kill Silverfish?

Although silverfish are not harmful to humans or pets, they can cause significant damage to household items. They prefer a diet filled with sugar and carbohydrates, which can be found in paper, soap residues, and even dust. They can damage books, stored food, clothing, wallpaper, and other starchy materials. Moreover, silverfish can trigger allergies in some individuals.

Does Bleach Kill Silverfish?

Yes, bleach can kill silverfish quickly and effectively. The active ingredient in bleach, sodium hypochlorite, works by eating away at the proteins in the silverfish, causing them to die. To use bleach for killing silverfish, mix two parts water with one part bleach in a spray bottle. Spray the mixture in areas where silverfish commonly thrive, such as cracks in walls or floors, damp and dark areas underneath and around sinks, and in bathtubs.

How to Use Bleach to Kill Silverfish

To use bleach effectively against silverfish, follow these steps:

1. Prepare a bleach solution by mixing two parts water with one part bleach in a spray bottle.
2. Spray and wipe your walls with the bleach and hot water mixture every three months until you notice that the silverfish have dissipated.
3. Pour a bleach and hot water mixture down your drains every day to kill the silverfish inside of your pipes.
4. Spray the bleach solution in areas where silverfish commonly thrive, such as kitchens, bathrooms, and boilers.

Remember to use caution when handling bleach, as it can be harmful or lethal if used incorrectly.

Risks of Using Bleach

While bleach is effective at killing silverfish, it can also be harmful if not handled properly. It can cause skin, eye, and respiratory irritation. Additionally, bleach can damage surfaces and materials in your home, such as fabrics, carpets, and wood. Always take precautions when using bleach, such as wearing gloves, a mask, and eye protection.
