Hello and thank you for contacting Willert Home Products. The No Moth Linen scented hanger will kill silverfish eggs and larvae infestations in clothing if the vapor is concentrated to a level that will kill the eggs and larvae.
For open areas we recommend using a fogger or spray - SLA Cedar Scented Spray to penetrate open areas in the home and around baseboards, doors and windows. This method will kill adult silverfish but wonâ¿¿t kill the eggs. Simple Boric Acid is effective in killing not only adult silverfish but also hatching nymphs.
Silverfish come out at night to seek food and water. They prefer dry food such as flour, cereals, pasta, and pet food and sizing in paper including wallpaper and book bindings, and starch in clothing. Other important sources of food include household dust, dead insects, and certain fungi also. However, silverfish can live for several months without nourishment. These teardrop-shaped insects are usually silver or brown in color and have three long bristles on their backs.
We recommend taking the following steps to eradicate Silverfish:
Determining If You Have a Silverfish Problem
Seeing the occasional silverfish around your home does not necessarily mean you have a problem, and it can be someone difficult to detect the presence of silverfish as they are very secretive and tend to hide under objects, especially cardboard boxes. They are largely nocturnal, and hide very well throughout the day. As mentioned, they are attracted to moisture, so they are most commonly found within bathrooms, kitchens, and basements. Homeowners are most likely to detect a silverfish infestation if, when they turn on a light in one of these rooms, silverfish dart across the floor or out of the tub. Another way that you can determine that you have a silverfish problem in your home is if you begin to notice the damage caused by their eating habits. Silverfish eat carbohydrates and starches, and are known for damaging wallpaper, cardboard, papers, and other feeding on flour, cereal, and pet food.
Reducing Your Chances of Developing a Silverfish Problem
Controlling humidity and moisture in the home is always a real challenge. If you want to make your home uninhabitable for silverfish, your best plan of action is to keep it as dry as possible. This may mean using dehumidifiers, or having your home inspected for any roof, foundation, or plumbing leaks. You can also reduce the risk of a silverfish infestation by separating them from their favorite food sources. This can mean cleaning any boxes and other clutter from basement and closet floors, and periodically cleaning and dusting bookshelves and desks where papers and books are left sitting. In the kitchen, keep normally boxed foods, such as cereals, in sealed plastic containers instead. Silverfish are also known for eating shampoos, so it can help to clean away residues from your bathtub after your shower.
