So you’ve just put up a new set of LED lights, and noticed an influx of spiders and other insects, and are wondering does LED lights attract spiders?

The quick answer is that LED lights attract a lot of different bug species in your house and surroundings, but spiders aren’t attracted to the bright lights themselves, but to the types of prey that are attracted to light.

What Bugs Are Spiders Attracted To? 

Spiders including nocturnal spiders are actually good for your home because every meal they eat is one bug eliminated for you, so you have fewer insects in your home Even though the food source that spiders are attracted to depends on the species, these predators are known to eat a variety of foods including flying insects such as mosquitoes, flies, moths and butterflies, and even other spiders.

The species of spiders range from tarantulas, wolf spiders to cellar spiders and crab spiders. These species of arachnids can be classified into two main types-web-building spiders and hunting spiders, where the former spider species consume flying insects, and the latter species of spiders could stay in concealed areas, and attack their prey like grasshoppers, crickets, and beetles as they come near.

But unlike a lot of other arthropods like ticks, mosquitoes, mites and chiggers that feed on human blood, most spider species have no interest in biting humans.

Why are Spiders Attracted to Light?

Most spiders are attracted to bright LED lights surrounded by flying insects. In fact, any light whether in gardens or homes attracts common insects, and spiders looking to prey on them and dead insects in the neighboring area.

LED lights emit a broader, warmer light compared to other types of light, which is just right for spiders to hunt for prey.

There are also certain light colors these eight-legged insects gravitate more towards than others such wolf spiders that are attracted to green wavelength.

Therefore, spiders aren’t exactly attracted to LED lights per se, but to the many bugs that tend to surround illuminated places because spiders will seek out any valuable food source.
