Why are silverfish attracted to LED lights?

Why are silverfish attracted to LED lights?- Silverfish are small, wingless insects that are often found in damp and dark areas of a house, such as basements, bathrooms, and kitchens. It has baffled householders and experts alike that these insects have a peculiar attraction to LED lights. This article will examine the factors that cause silverfish to be drawn to LED lights as well as prevention measures for homeowners.

What are LED lights?

It’s crucial to first comprehend what LED lights are and how they operate. A semiconductor device known as a “light-emitting diode,” or simply “LED,” creates light when an electric current is sent through it. LED lights generate a calm, white light that is brighter and uses less energy than conventional incandescent bulbs. Additionally, they are made to last a lot longer than other types of bulbs.

Why are silverfish attracted to LED lights?

  • Silverfish are drawn to LED lights for a variety of reasons, including the unique spectrum of light that these insects find attractive. Compared to conventional incandescent bulbs, LED lights emit a greater percentage of blue light. Because blue light has a shorter wavelength than other colors, insects like silverfish can see it better. Since these insects rely on light to find food and navigate, they are drawn to light sources by nature.

The following table lists various types of light bulbs along with how attractive they are to silverfish:

Light Bulb TypeWavelengthAttraction to Silverfish
LED (cool white)Short (high proportion of blue light)High
LED (warm white)Longer (lower proportion of blue light)Lower

The various light bulb types and the degree of silverfish attraction are listed in this table. It provides details on each type of bulb’s wavelength as well as its level of silverfish attraction. This table can make it simple for readers to examine the various light bulb options and decide which type to use in their homes.

  • Silverfish are drawn to LED lights because they resemble the natural light that these insects experience in their surroundings. Silverfish are typically found in damp, gloomy places like caves and fissures in the wild. Moonlight and starlight, which have a spectrum of light similar to that of LED bulbs, are often the sources of illumination in these places. This means that silverfish may confuse LED lights for natural light sources and be attracted to them when they come into contact with them.

Also noteworthy is the fact that silverfish are drawn to LED lights for the same reason they are to other lights like windows and lamps. These insects need light to navigate because they are phototropic, which means they are drawn to it. Additionally, they are nocturnal, meaning that they are most active at night when they have a higher chance of coming across light sources.

How to keep silverfish away from LED lights?

  • Changing to light bulbs with a longer wavelength that are less visible to insects, such as yellow or orange, is one alternative. These bulbs produce a warm, gentle light that deters silverfish and other insects. Utilizing LED lights with a warmer color temperature is an additional choice because they emit less blue light and are less alluring to silverfish.
  • Homeowners can take steps to lessen the overall allure of their homes to silverfish in addition to changing the light bulbs. Given that silverfish like moist settings, this also entails lowering moisture levels by repairing leaks and utilizing dehumidifiers. To keep silverfish out of the house, owners should caulk gaps and crevices in the walls, floors, and ceilings. Regular vacuuming and clutter removal can also aid in eradicating pests’ hiding areas, such as silverfish.


Finally, there are a number of explanations for why silverfish are drawn to LED lights, including their spectrum of light and resemblance to natural light sources. By switching to yellow or orange light bulbs, utilizing LEDs with a warmer color temperature, and taking steps to lower moisture levels and remove silverfish hiding areas, homeowners can take measures to lessen the attraction of their houses to these insects. Homeowners can benefit from LED lighting without luring unwelcome bugs inside their residences by following these instructions.
