What Attracts Silverfish to Florida Homes?
Silverfish are among the most frustrating pests to discover inside your home. They’re fast and elusive, and they always seem to show up in the worst places, like your bathroom drawer or your favorite book. While they don’t bite or spread disease, they can cause noticeable damage to your belongings and even signal other pest issues in your home.
So, what attracts silverfish to Florida homes? The answer lies in a combination of factors that make your house the perfect environment for them.
In this article, we’ll break down what attracts silverfish, why Florida homes are especially vulnerable, and what you can do to stay ahead of a silverfish infestation.
Key Takeaways
- Silverfish are attracted to Florida homes because of high humidity, dark crawl spaces, damp basements, and cluttered garages.
- Favorite food sources include cardboard, wallpaper glue, book bindings, dead insects, pet food, and pantry carbohydrates.
- Prevention starts with lowering humidity, sealing crevices, vacuuming hiding spots, and storing food in airtight containers.
- Long-term control depends on breaking their lifecycle with consistent prevention and expert help from professional pest control.
High Humidity in Crawl Spaces, Attics, and Basements
Florida’s year-round high humidity is one of the biggest silverfish attractants.
These insects are drawn to damp environments, especially in parts of your home where air doesn’t circulate well. Crawl spaces, attics, and basements are classic hiding spots.
Without a dehumidifier or proper ventilation, these areas can remain moist and dark, making them ideal for laying eggs and completing their lifecycle.
Cluttered Garages and Cardboard Boxes
Garages in Florida often double as storage areas filled with cardboard boxes, paper products, and old belongings. Cardboard contains cellulose, one of the many food sources silverfish eat.
The combination of clutter and humidity creates plenty of moist areas and hiding spots for these insects to settle in undisturbed.
Food Sources Rich in Starches and Carbohydrates
Pantries are another hotspot, especially when food is stored in paper packaging or non-sealed containers.
Silverfish eat a wide range of carbohydrate-rich materials, including flour, sugar, oats, and even dry pet food. These starchy items serve as primary food sources. Using airtight containers or sealed containers helps reduce the risk.
Leaky Pipes and Poor Ventilation in Laundry Rooms
Laundry rooms often have high humidity, warm temperatures, and access to a water source, which checks all the boxes for what attracts silverfish.
Even a small drip from leaky pipes or condensation from your washer can create damp areas where they can thrive. Poor airflow exacerbates the problem, especially when a dehumidifier is not in place.
Damaged Wallpaper and Adhesives
Silverfish are known to chew on wallpaper.
Not because they like the paper itself but because of the adhesives behind it. These glues often contain starch, which silverfish feed on.
You may notice yellow stains or holes in the wallpaper near baseboards or in crevices, especially in bathrooms or older homes.
Books, Paper Goods, and Book Bindings
If you have bookshelves or stacks of paper sitting in humid areas, you may be unknowingly feeding a silverfish population. Book bindings, especially those from older times, are typically made with starch-based glue.
In Florida, homes with limited climate control or poor insulation can become major attractants for paper products in dark places.
Dead Insects and Secondary Pests
Silverfish will eat dead insects like roaches or termites, especially when their usual food supply is limited. If you’re dealing with other pest issues, such as cockroaches or bed bugs, you might unknowingly be exacerbating your silverfish problem.
This is where comprehensive pest management becomes essential.
How to Get Ahead of a Silverfish Infestation
Spotting one in your bathroom or under the kitchen sink usually means there is more hiding nearby. Fortunately, there are steps you can take to not only kill silverfish but also prevent them from coming back.
Monitor and Control Indoor Humidity Levels
Start with the moisture.
A dehumidifier in humid environments, such as basements, crawl spaces, and laundry rooms, helps reduce the moisture that silverfish rely on. Aim to keep indoor humidity levels below 50%.
This simple step can significantly reduce the attractiveness of your living spaces to these pests.
Seal Cracks and Crevices With Caulk
Silverfish sneak in through small gaps around plumbing, under baseboards, and cracks in the foundation. Use caulk to seal cracks and entry points around the home, paying particular attention to areas with high moisture levels, such as kitchens and bathrooms.
This not only blocks access but also helps reduce hiding spots.
Store Food in Airtight Containers and Declutter Storage Areas
When you store food in airtight containers, you limit access to silverfish food sources. Switch from paper packaging to sealed containers for items like rice, cereal, sugar, and pet food.
Also, avoid using cardboard boxes for long-term storage, especially in garages and closets, where humidity and cellulose-rich materials provide a double attractant.
Remove Attractants and Vacuum Regularly
Silverfish feed on a wide range of materials, including book glue, hair bristles, and dust.
Regular vacuuming, especially along baseboards and around paper clutter, helps eliminate silverfish eggs, shed skins, and food debris. Use a crevice attachment to clean hard-to-reach corners and reduce their access to food.
Use Diatomaceous Earth and Natural Repellents
Diatomaceous earth is a natural, pet-safe powder that damages the hard shell of wingless insects like silverfish. Apply it behind furniture, around baseboards, and in closets where they tend to travel.
Some homeowners also use natural repellents, such as essential oils, although these should be used with caution and only in well-ventilated spaces.
Don’t Overlook the Lifecycle
Getting rid of silverfish doesn’t end the problem.
Eggs can remain hidden in cracks and moist areas for weeks. Breaking the lifecycle requires consistent effort, including vacuuming, reducing moisture, and eliminating attractants.
Professional pest control can help ensure that all stages of the lifecycle are treated.

Frequently Asked Questions
Can silverfish spread from one home to another?
Yes, silverfish can move between homes, especially in multi-unit buildings. They use plumbing lines, wall gaps, or attic spaces to travel, especially when nearby units have moisture or clutter that attracts them.
Will silverfish ruin clothes in my closet?
Silverfish can damage clothing made from cotton, silk, or linen, especially if items have sweat, food stains, or starch-based treatments. They’re often found in dark closets with limited airflow and high humidity.
Does having silverfish mean I have other pests?
Silverfish don’t cause other infestations, but they can feed on dead insects like cockroaches or termites. If you see both, it may be a sign of broader pest activity or hidden moisture problems.
