Natural Pesticide for Silverfish
Although silverfish can be nuisances, they typically cause little damage and do not spread disease. However, if uncontrolled, silverfish infestations can damage book bindings, paper, leather, wallpaper and fabrics like silk and rayon. Does this Spark an idea?

Description
-
Full-grown silverfish are approximately 1/2 inch long with a carrot-shaped body narrowing toward the rear. Their body is silver with three tail-like appendages at their back end. Silverfish hide during the day and become active at night. They prefer dark, cool and damp places and are often found in cellars, closets and storage areas.
Control Options
-
Several natural pesticides are available to manage silverfish. One effective broad-based insecticide is d-limonene, which is contained in extracted oil from citrus rinds. Another option is boric acid. This naturally occurring mineral abrades the silverfish's exoskeleton, causing it to desiccate and die within three to 10 days. Diatomaceous earth, also called silicon dioxide, is a third natural pesticide for managing silverfish.

Other Considerations
-
Using dehumidifiers, repairing leaky pipes and roofs and ventilating closed rooms decrease silverfish populations. Remember to always use pesticides as directed and required by the U.S. Environmental Protection Agency. Use pesticides only in areas inaccessible to children and pets.
