Exterminating pesky silverfish can be tricky business. Though not poisonous, these tiny silvery-gray pests can leave you with damaged books and hole-filled clothes. As the name implies, this particular pests have a tapered abdomen that gives them a fish-like appearance.
The nocturnal silverfish makes his move at night, searching for starchy sources of 'food' such as clothing, paper, books, and other various dry pantry goods. Though the silverfish can make it's presence known by the damage left behind, they can go for months without nourishment- making them particularly difficult to exterminate.
Think you may have a silverfish infestation? Some signs to watch for include: small, irregular holes in clothing or paper, irregular-shaped dark spots on books, 'scraped' book bindings and iridescent, dusty scales around or below the damaged items.
Silverfish can invade your home because of dry, hot outside temperatures. The silverfish prefers a dark, humid, damp environment to thrive. Be sure to keep closets, bathrooms, laundry rooms and basements as dry as possible.
In order to completely exterminate silverfish a professional insecticide must be applied by spraying the interior baseboards. The outside of the house must be treated as well by spraying the exterior base, windows, doors, eaves and spreading granules around house. Finally, a fine chemical powder is misted into the structure's attic.
