Silverfish

Silverfish get their name from being small, having no wings and moving so quickly you might think they're swimming. The dampness and dark of your house can make these insects hide and quietly ruin your property.

What are Silverfish?

Silverfish are very small, without wings, and they look and move like fish—earning their name from being silver and gray. Their bodies typically measure 1/2 to 3/4 inches, are slender, flat, and shaped like a carrot or tiny fish. They have long antennae at the front and three tail-like extensions at the back. Their metallic scales make them easily recognizable. Silverfish are nocturnal pests that prefer dark areas and typically hide in damp places such as bathrooms, basements, attics, kitchens, and laundry rooms.

What Do Silverfish Eat?

Being herbivores, silverfish diet includes starchy materials like paper, books, wallpaper, cardboard, glue, textiles, and even dried foods such as flour, cereal, and pasta. They can also feed on synthetic fabrics and, occasionally, dead insects. While silverfish don't bite or transmit disease, they can cause significant damage to books, important documents, clothes, and food supplies.

Silverfish Infestation

Many American households, especially in the Southeast, Midwest, and coastal regions, are vulnerable to silverfish infestation due to high humidity and ample food sources. Although silverfish aren't harmful to people or pets, they can contaminate food, destroy valuables, and trigger allergies through their shed scales and droppings.

Where do silverfish come from

The most common silverfish in United States households are Common Silverfish, Gray or Long-tailed Silverfish, Four-Lined Silverfish, and Firebrat. The main cause of these insects entering our homes is that they prefer warm, humid, and dark environments, which our homes provide in attics, basements, bathrooms, and kitchens. They also have easy access to a food source, consisting of starches, glue, paper, and textiles. The primary causes of their invasion of the indoor areas include moisture, food supply and clutter; leaks, high humidity and food stored in an unprofessional manner render the households especially attractive to them.
