True to their name, silverfish have metallic silver scales and wiggle like swimming fish as they sprint across floors. Their flat, carrot-shaped bodies measure about 3/4 inch long when mature. Immature silverfish look like adults, only smaller.
Also known as "bristletails," silverfish have three long, tail-like structures to complement two long antennae on their heads. Firebrats, a close relative, look the same except they're mottled brown. Both these pests often seek out moisture in homes during extended dry seasons. Once inside, they can live for many years.
SIGNS OF SILVERFISH
Silverfish hide during daylight and come out at night, so you rarely see them. If you do, it's often in the early morning near a bathroom or kitchen sink drain. When disturbed, silverfish move quickly — a behavior that draws comparisons to cockroaches.
Silverfish are best known for destroying books by feeding on book-binding glue and paper. But they also eat fabrics, wallpaper, cereals and more. Silverfish feed by scraping, leaving scrape marks, irregular holes and excrement between book pages.

SILVERFISH CONTROL TIPS
Overly humid basements and minor plumbing leaks invite silverfish to stick around. Repair plumbing leaks promptly and use dehumidifiers, if needed, to turn the tables back in your favor.
Always read product labels and follow the instructions carefully.
