If you would prefer to not have silverfish near your home, it is a good idea to address:
Leaky spigots that allow puddles to form and soil to become moist.
Obstructed or broken gutters that allow water to run down the side of your home. When water is not properly channeled away from the wall of a home, it creates the conditions for wood rot and moisture build up in perimeter soil, both of which are attractive to silverfish.
Trees, bushes, and other objects that create shaded areas where soil cannot be dried by the sun after it rains.
