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?
Yes, bleach can effectively kill silverfish. The active ingredient in bleach, sodium hypochlorite, breaks down the proteins in the silverfish, causing them to die. However, bleach should be used with caution as it can be harmful to humans and pets and can damage surfaces and materials in your home.
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.
