Do LED Lights Attract Silverfish? Exploring the Connection
LED lights have gained popularity in recent years for their energy efficiency, longevity, and versatility in various applications. While LED lights have numerous advantages, a question that frequently arises is do LED lights attract silverfish and other bugs.
In this blog, we will dive into the intriguing connection between LED lights and silverfish to separate fact from fiction. We will explore the behavior of silverfish, shed light on the characteristics of LED lights, and examine the factors that might contribute to silverfish sightings in proximity to LED lighting.
Understanding Silverfish
Silverfish, scientifically known as Lepisma saccharina, are small, wingless insects that belong to the order Zygentoma. They are aptly named for their silvery-gray color and fish-like movements. Measuring about half an inch in length, silverfish have elongated bodies with three long, tail-like appendages at the rear and two antennae at the front.

These nocturnal creatures are primarily active during the night and prefer dark, undisturbed areas. They have a distinct preference for environments with high humidity levels, typically between 75% and 95%.
Due to their moisture requirements, silverfish are commonly found in bathrooms, kitchens, basements, attics, and other areas with water sources or dampness.
Silverfish have a particular appetite for starchy materials found in books, wallpaper, and glue bindings. Hence, they can be found lurking in libraries, bookstores, and homes with extensive book collections.

Do LED Lights Attract Bugs?

LED lights are not inherently attractive to bugs. Unlike more traditional incandescent bulbs or fluorescent lights, LED light bulbs do not emit a significant amount of ultraviolet light, which is known to attract bugs.
Insects, particularly nocturnal ones, are highly sensitive to UV light and are naturally drawn to it. However, LEDs emit very little UV light, making them less attractive to bugs compared to other light bulbs.
Heat is another factor that can attract certain bugs. For example, some flying insects, like moths, are attracted to the warmth of light emitted by incandescent lights. With LED lights generating less heat, they are less likely to draw in these heat-seeking insects.

Examining the Claim: Do LED Lights Attract Silverfish?
The short answer is no, LED lights do not inherently attract silverfish. Silverfish are not naturally drawn to light sources like other pests, such as moths or flies.
Unlike most bugs these flying insects that are attracted to light, silverfish exhibit negative phototaxis, meaning they tend to avoid light and prefer dark, undisturbed areas.
LED lights emit minimal UV light, which is one of the factors that attract bugs. Since silverfish are not attracted to UV light, LED lights do not specifically lure them toward the light source. Therefore, you can safely install LED lights without worrying about silverfish infestations caused by the lighting itself.
Why Are Silverfish Attracted to LED Light?
Silverfish are not attracted to LED lights. They are attracted to moisture, warmth, yellow light, and dark places. LED lights emit less heat than other types of light bulbs, so they may help to keep silverfish away.
However, there are instances where silverfish may be observed in proximity to LED lights, which can lead to the misconception that they are attracted to the light bulb or the lights themselves.

Factors that Attract Silverfish

Common Usage in Silverfish-Prone Areas
LED lights are often installed in areas like bathrooms and kitchens, which are environments where silverfish tend to thrive due to the presence of moisture. Therefore, it is possible to observe silverfish near LED lights, but their presence is due to the existing favorable conditions in these spaces, not the attraction to the lights or led bulbs themselves.
Increased LED Light Usage
As LED lights have become more popular, you might notice more silverfish in your home coincidentally. However, this correlation does not imply causation.
The increased presence of silverfish can be attributed to other factors such as environmental conditions or changes in their habitats, rather than the usage of LED lights.
Nocturnal Activity and Lighting
Silverfish are nocturnal creatures, meaning they are more active during the night. Therefore, when LED lights are on during the night, it may increase the chances of spotting silverfish.
However, their presence near the bright lights is not due to attraction but rather their natural behavior or their attempts to find food sources.
Do LED Strip Lights Attract Silverfish?
LED strip lights do not inherently attract silverfish. Silverfish are not naturally drawn to blue light wavelengths or sources and do not exhibit positive phototaxis.
LED strip lights emit minimal ultraviolet light, which is known to attract insects, including some flying pests like moths. Since silverfish do not respond to UV light, they are not specifically attracted to LED strip lights.
Practical Tips for Silverfish Prevention
Control Moisture Levels
Silverfish thrive in damp and humid environments, so it’s essential to address any moisture issues in your home. Fix leaks, improve ventilation, and use dehumidifiers in areas prone to high humidity such as bathrooms, basements, and kitchens.
By reducing moisture, you make your home less attractive to silverfish.
Seal Entry Points
Silverfish can enter your home through small cracks and gaps in walls, windows, doors, and foundations. Inspect your home for potential entry points and seal them with caulk or weatherstripping. This helps prevent silverfish from gaining easy access and establishing a presence in your living spaces.
Declutter and Organize
Silverfish thrive in cluttered environments where they can find hiding spots. Regularly declutter and organize your belongings, especially in storage areas like basements and attics.
Use airtight containers to store items such as books, clothing, and paper goods, as silverfish are attracted to starches and sugars found in these materials.
Vacuum Regularly
Vacuuming your home regularly helps remove silverfish eggs, nymphs, and adults. Pay close attention to areas where silverfish are likely to hide, such as cracks, crevices, baseboards, and carpets. Empty the vacuum bag or canister outside to prevent any captured silverfish from reinfesting your home.
Proper Food Storage
Silverfish are attracted to food sources, particularly those rich in starches and sugars. Store pantry items like cereals, flour, and pet food in airtight containers to prevent silverfish from accessing them.
Keep kitchen counters and floors clean, wiping up any spills or crumbs that may attract bugs & silverfish.
Reduce Excess Moisture in Bathrooms
Silverfish often congregate in bathrooms due to the high humidity. After taking showers or baths, use exhaust fans or open windows to reduce moisture build-up. Wipe down wet surfaces and fix any plumbing leaks promptly.
Use Desiccants and Natural Repellents
Silverfish are sensitive to drying agents like silica gel or diatomaceous earth. Place these desiccants in areas where silverfish are likely to hide, such as closets, cabinets, and bookshelves.
Additionally, some natural repellents like cedar shavings, citrus peels, or lavender sachets may help deter silverfish, although their effectiveness may vary.
Regular Inspection
Conduct routine inspections of areas prone to silverfish infestation, such as dark corners, cracks, and behind furniture. By catching any signs of silverfish early on, you can take prompt action to prevent a full-blown infestation.
Professional Pest Control
If you’re dealing with a persistent silverfish problem or if the infestation is extensive, consider contacting a professional pest control service. They can provide effective treatments and offer expert advice on preventing future silverfish infestations.
Final Words
The claim that LED lights attract silverfish is unfounded. Silverfish are not naturally drawn to artificial light from sources, including LED lights. They are primarily attracted to moisture, warmth, and dark places. LED lights emit minimal UV light and do not have any inherent attractive properties for silverfish.
While LED lights can attract spiders or silverfish, this is often due to other factors such as existing infestations in moisture-prone areas or the nocturnal activity of silverfish coinciding with the light being on during the night. LED lights themselves do not attract silverfish.
