Silverfish are a small insect with a long, slender flat body, with three long bristles coming off their back end. They have a scary disposition, but that is not entirely true. Silverfish are about 1/2 – 1 inch in size, have a shimmery grey to blue color, and move in fish-like motions. These characteristics all lend the silverfish its name.
They do not have wings, but they move very quickly. Silverfish are nocturnal, love high levels of humidity, and are active year-round. Meaning yes, they unfortunately do not hibernate.
Silverfish Behavior, Diet & Habits
Capable of surviving in most climates, silverfish prefer humid environments. Silverfish feed on carbohydrates, mostly sugar and starches. In your household, a silverfish diet could consist of feed, clothing, paper, wallpaper, books, photos, flour, sugar, oats, and other items that are high in sugar and starch.
Silverfish are nocturnal and secretive. The seriousness of the infestation may not be noticed for long periods of time, exasperating the silverfish infestation. In your household, silverfish are frequently found in basements, kitchen cupboards, attics, bathrooms, under sinks, and in laundry rooms.
Although they are a bit creepy-looking, silverfish do not bite or carry diseases. They are considered to be more of a nuisance pest, as they love to feed on paper and can pose threat to items stored in cardboard boxes.
Silverfish Prevention & Treatment
Silverfish enjoy high levels of humidity, so a part of silverfish prevention is controlling the humidity. This process includes opening vents in basements, using baseboards with caulk, and limiting the amount of feeding sites. If your home has a silverfish problem, it is recommended to hire a professional pest control expert to create a custom approach to rid your silverfish population.
