Silverfish might not be the first bug that comes to mind when you think of pests, but these tiny, wriggling insects can cause damage and become a real nuisance in homes and businesses. If you’ve ever spotted one darting across your floor, you may have wondered: Are silverfish harmful? Do they bite humans or pets? Should you be worried about an infestation? In this guide, we’ll give you a full picture of everything you need to know about silverfish, their potential risks, and how to get rid of them for good.
What Are Silverfish and Why Should You Be Concerned?
Silverfish are small, wingless insects that have been around for over 400 million years. These nocturnal pests are known for their silvery, metallic appearance and their quick, fish-like movements. While they don’t bite humans or animals, they can infest homes in large numbers, feeding on a variety of starchy materials like paper, wallpaper, and even clothing made of silk or cotton.
Silverfish Are Nocturnal and Hard to Spot
Silverfish are nocturnal, meaning they are most active at night. Because of this, a silverfish infestation can go unnoticed for a long time. If you see silverfish scurrying away when you turn on the lights, chances are there are many more hiding in cracks and crevices throughout your home.
Silverfish Can Cause Damage to Books and Household Items
Silverfish eat glue, paper, and other starchy materials, making books, magazines, and wallpaper prime targets. Over time, their feeding habits can cause damage to books and magazines, as well as clothing and stored food sources. If you notice chewed-up pages or small holes in your fabrics, silverfish might be to blame.
Are Silverfish Harmful to Humans or Pets?
A common concern for homeowners is whether silverfish are harmful to humans and pets. Let’s clear up the facts.
Silverfish Don’t Bite or Sting
Unlike some other household pests, silverfish don’t bite humans or pets. They lack the mouthparts necessary to bite or sting, and they do not transmit diseases. This makes them less of a direct health threat compared to other insects like cockroaches or bed bugs.
Silverfish Can Trigger Allergic Reactions
Although silverfish are not harmful to humans in the traditional sense, they can contribute to allergic reactions in sensitive individuals. Their shed scales and droppings can mix with household dust, potentially triggering allergies or asthma symptoms in some people.
Silverfish Are Not Harmful to Pets
If you have cats and dogs, you might wonder if silverfish are harmful to pets. The good news is that silverfish don’t bite humans or pets, and they don’t carry any known diseases that can affect animals. However, their presence can still be annoying, especially if they infest food storage areas.
What Do Silverfish Eat and Why Are They in Your Home?
Silverfish are attracted to areas with food sources that contain starch and carbohydrates. When you know about their diet, you prevent an infestation.
Silverfish Feed on Starchy Materials
Silverfish are known to feed on a variety of starchy materials like paper, book bindings, wallpaper glue, and even fabrics made of silk or cotton. They may also infest food storage areas, feeding on dry goods like flour, oats, and sugar.
High Humidity Attracts Silverfish
Silverfish thrive in damp areas with high humidity, such as bathrooms, basements, crawl spaces, and attics. If you have leaky pipes, poor ventilation, or condensation buildup, your home could be a perfect breeding ground for silverfish.
Silverfish Can Survive Long Periods Without Food
Even without food, silverfish can survive for long periods without eating. This makes them particularly resilient pests that can continue to infest a home even if food sources are removed.
How to Prevent Silverfish Infestations
Preventing silverfish starts with making your home less inviting to these nuisance pests. Here are some effective methods to keep silverfish away:
Reduce Humidity With a Dehumidifier
Since silverfish thrive in humid environments, using a dehumidifier can make your home less attractive to them. Focus on areas like basements, crawl spaces, and attics where moisture tends to accumulate.
Seal Cracks and Crevices
Silverfish often hide in cracks and crevices during the day. Sealing these entry points can help prevent an infestation from taking hold.
Store Food in Airtight Containers
To prevent silverfish from accessing food sources, use plastic or glass airtight containers to store dry goods like flour, sugar, and cereals.
Clean and Dry Your Home Regularly
Regular cleaning, vacuuming carpets, and discarding anything that could serve as a food source can help eliminate silverfish activity in your home.
Methods to Get Rid of Silverfish
If you already have a silverfish infestation, there are several ways to eliminate them effectively.
Use Diatomaceous Earth and Boric Acid
Dusts like diatomaceous earth and boric acid can be sprinkled in infected areas to kill silverfish. These powders work by dehydrating and eliminating the pests.
Consult a Pest Control Professional
If a silverfish problem persists, it’s best to use a pest control professional to assess the situation and provide long-term solutions. With a professional pest control provider by your side, you can rely on their expertise to identify problem areas and apply targeted treatments to eliminate silverfish effectively.
