Do LED Lights Attract Silverfish? Unveiling the Myth


Silverfish, those tiny wingless insects that scuttle across your bathroom floor or crawl through your bookshelves, are often the cause of annoyance and concern. Many homeowners have heard the rumor that LED lights can attract silverfish, but is there any truth to this claim? In this article, we will delve into the topic and separate fact from fiction.

Understanding Silverfish Behavior

Before we can determine if LED lights attract silverfish, it's essential to understand their behavior. Silverfish are nocturnal creatures that prefer dark and damp environments. They are attracted to moisture and humidity, which is why they are commonly found in bathrooms, basements, and kitchens. These pests feed on starchy materials, such as paper, glue, and even clothing.

Debunking the Myth

Contrary to popular belief, there is no scientific evidence to suggest that LED lights attract silverfish. idea that silverfish are drawn to LED lights may have originated from their natural attraction to bright light sources. However, silverfish are generally repelled by light and prefer dark hiding places. Therefore, it is unlikely that LED lights would attract these pests.

Other Factors that Attract Silverfish

While LED lights may not be the culprit, there are other factors that can invite silverfish into your home. Excess moisture and humidity are prime conditions for silverfish infestations. Leaky pipes, damp basements, and poorly ventilated areas create an ideal habitat for these pests. Additionally, cluttered spaces provide ample hiding spots, making it easier for silverfish to establish a presence.

  • 1. Moisture: Silverfish are attracted to areas with high humidity levels, as they require moisture to survive. To attract silverfish, create moist environments by leaving damp towels, wet clothes, or wet surfaces around the house.
  • 2. Darkness: Silverfish are nocturnal creatures and are attracted to dark and dimly lit areas. They prefer hiding in cracks, crevices, and dark corners. To attract silverfish, leave areas of your home dark and undisturbed.
  • 3. Food sources: Silverfish feed on carbohydrates, such as sugars and starches. They are attracted to food sources like paper, glue, cardboard, and book bindings. To attract silverfish, leave food sources accessible, such as stacks of newspapers or cardboard boxes.
  • 4. Clutter: Silverfish are attracted to cluttered areas where they can easily find hiding spots. To attract silverfish, leave clutter around your home, such as piles of old books, magazines, or clothes.
  • 5. Warmth: Silverfish are attracted to warm temperatures, thriving in environments between 70-80°F (21-27°C). To attract silverfish, maintain warm temperatures in your home by using heating systems or keeping certain areas insulated.
  • 6. Lack of ventilation: Silverfish prefer areas with poor ventilation as it helps maintain moisture levels. To attract silverfish, limit airflow and ventilation in certain areas of your home by keeping windows closed or obstructed.

It's important to note that while these factors may attract silverfish, they are considered pests and can cause damage to your property. Taking preventive measures to eliminate or control silverfish infestations is recommended.

Preventing Silverfish Infestations

Now that we know LED lights are not a major factor in attracting silverfish, let's explore some preventive measures to keep these pests at bay:

1. Reduce Moisture Levels

Fix any leaks, improve ventilation, and use dehumidifiers to reduce moisture levels in your home. By eliminating excess moisture, you create an environment that is less appealing to silverfish.

2. Seal Entry Points

Inspect your home for any cracks or gaps and seal them properly. Pay close attention to areas around pipes, windows, and doors. By blocking potential entry points, you can prevent silverfish from invading your living space.

3. Declutter Regularly

Silverfish thrive in cluttered environments as they provide hiding places and food sources. Regularly declutter your home, especially in areas where silverfish are commonly found, such as bookshelves and storage spaces.

4. Store Food Properly

Keep all food items, including pet food, in sealed containers. Silverfish are attracted to starchy foods, so proper storage can minimize their access to potential food sources.


In conclusion, LED lights do not attract silverfish. These pests are more likely to be attracted to dark and damp environments rather than sources of light. By understanding silverfish behavior and taking preventive measures to reduce moisture levels and eliminate hiding spots, you can effectively keep silverfish at bay. Remember, when it comes to silverfish prevention, proper hygiene and home maintenance play a crucial role.
