Threats of Silverfish Infestation
Silverfish typically run quickly and are mostly active at night. Capable of thriving in most climates, silverfish can survive almost anywhere, but they prefer areas with high humidity. In homes, they prefer dark, damp areas and are commonly found in kitchens and bathrooms, laundry rooms, closets, basements, attics or near bookcases and hide behind baseboards or casings around doors and windows. Medically harmless, silverfish are primarily a nuisance pest and can contaminate food, damage paper goods, and stain clothing.
Silverfish are chewing insects known for their destructive feeding habits and have been known to ruin papers, clothes, and wallpaper. They consume a variety of foods but prefer carbohydrates (sugars and starches) and protein, including flour, dried meat, rolled oats, paper, linen, silk, and even glue and book bindings. They have also been found in unopened food packages. They can survive long periods, sometimes over a year, without food, but are sensitive to moisture and require high humidity to survive.
Identifying a Silverfish Infestation
Homeowners often detect silverfish when they find one on the floor or in a sink or bathtub. Damage caused by their feeding can also indicate the presence of silverfish, along with their tiny pepper-like feces. They are especially attracted to paper and damp clothing and are commonly found in stored boxes in garages and sheds. If you suspect a silverfish infestation, examine any boxes or bags containing papers or old clothing.
