What’s a Silverfish?
A silverfish is a small, wingless insect known for its silvery-blue color and fish-like movements. These nocturnal creatures are typically about 12-19 millimeters long and have a tapered, carrot-shaped body with long antennae and three tail-like appendages. Silverfish thrive in moist, dark environments and are commonly found in basements, bathrooms, and kitchens, where they feed on starchy materials like paper, glue, and textiles. Despite their unsettling appearance, silverfish are generally harmless to humans but can cause damage to household items and contaminate food sources.
Here are the most prevalent silverfish found in Southern California.
Common Silverfish
The common silverfish, identifiable by its shiny silver scales, prefers cooler, damp areas.
Firebrat
The firebrat, which is usually a mottled gray or brown, thrives in hotter environments like attics and near furnaces.
Grey Silverfish
The gray silverfish, slightly larger and darker than its common counterpart, can adapt to a variety of conditions, often making its home in both indoor and outdoor settings.
Each of these species is adept at surviving in the varied climates of Southern California, contributing to their prevalence in the region.
