Incandescent bulbs bring in the largest insect haul, averaging about eight per hour. The “bug lights” and warm-colored LEDs were roughly tied for least attractive, at about 4. 5. Overall, incandescent light bulbs pulled in the highest number of insects, followed by CFL, halogen globes, and cool-colored LEDs. The second best light was the “bug light”. Research shows bugs are least attracted to warm colored LED lights and most attracted to blue colored UV lights.
LED lights do attract bugs but not as much as traditional lights do. Bugs are drawn to LED lights that have a shorter wavelength and produce UV light, as well as those that emit a bright blueish light. This is because many insects use UV light. LED lights are less attractive to many types of insects compared to incandescent or fluorescent bulbs. UV light is highly visible to insects and is a significant attraction to them.
Newer LEDs have insect-repelling features, but no lighting is entirely bug-proof. White and blue LED lights attract the most amount of bugs, with ultraviolet and green LED lights also attracting bugs. Red LED lights are the most attractive.
Incandescent light bulbs attracted the most insects (with fluorescent bulbs coming in second), while LEDs, particularly those with a higher coloring index, have an increased ability to attract bugs. LED streetlights are wreaking havoc on pollinators in cities, cutting insect populations by 50 in one study. It’s not so much the lighting itself that attracts insects, but the factors influencing their behavior, such as light wavelengths and heat.

Do Insects Get Attracted To LED Bulbs?
Insects are naturally drawn to lights emitting UV rays and heat, with incandescent bulbs being particularly attractive due to their warm light and UV emission. In contrast, LED lights produce less heat and very limited UV, making them less appealing to bugs. While LEDs do attract insects, their influence is significantly lower compared to traditional bulbs. Specifically, LED lights with shorter wavelengths or those emitting bright blue light attract more insects due to many insects' navigation reliance on UV light.
Incandescent bulbs have been found to attract a higher volume of insects, averaging eight per hour, while warm-colored LEDs and specific "bug lights" draw the fewest, approximately 4. 5 insects. Research indicates that light sources like CFL, halogen lights, and cool-colored LEDs also attract insects but not as intensively as incandescent lights. Yellow and amber LED lights attract the least, while white and blue LEDs are more enticing.
Though LED lights do attract some insects, particularly those that emit UV-rich spectra, such as moths and flies, advancements in LED design have improved insect-repelling features. Despite this, no lighting is completely bug-proof; notably, cockroaches are generally averse to light. LEDs are quieter compared to traditional bug zappers, enhancing their appeal for outdoor use, particularly in reducing insect attraction.
In summary, while insects are attracted to light, LED options are less inviting than conventional incandescent or fluorescent lights, especially when using warm tones. Yellow, orange, and red LEDs pose minimal attraction to bugs, demonstrating that not all lighting equally entices these creatures.
What Color Light Is Best For Sleep?
The optimal night light colors for sleep are red and amber, which offer warmth and a soothing effect conducive to restful slumber. These colors, located close to red on the light spectrum, are believed to stimulate melatonin production, an essential sleep hormone. Red light, having a lower color temperature than typical sunlight, serves as a preferable choice for nighttime illumination. Warm tones of red, orange, and yellow effectively prepare the mind and body for sleep.
Understanding the impact of light on sleep is crucial; bright white or yellow light is better suited for alertness during waking hours, while blue and green lights may disrupt sleep patterns. Night-mode settings on devices attempt to mitigate the effects of harmful blue light.
Experts highlight red light’s calming attributes and suggest that lower brightness levels can significantly affect mood and sleep quality. Evidence supports that red and amber are ideal for creating sleep-friendly environments. Products such as SweetDreams Sleep Lights are designed with these warm hues for nighttime use.
To improve sleep, it is advisable to maintain a dark room but utilize warm light colors when necessary. Research indicates that avoiding bright and harsh lighting, particularly in the hours leading to bedtime, fosters better sleep quality. Aiming for darkness, supplemented by red light if needed, enhances relaxation. In summary, maximizing exposure to natural sunlight during the day and minimizing blue light exposure in the evening establishes a conducive environment for restorative sleep.
What Color Light Do Mosquitoes Hate?
Mosquito Prevention and Control
To effectively deter mosquitoes, it's essential to understand their attraction to color and light. Although mosquitoes are attracted to light, yellow bulbs are often recommended as the best choice since this wavelength is less visible to them, making it more challenging for them to locate hosts. Mosquitoes are also known to avoid light colors that reflect heat, with white being particularly effective as a deterrent.
Research indicates that mosquitoes favor dark, shady areas to maintain moisture and are attracted to body heat, leading them to prefer dark clothing, such as black and navy blue. To combat this, wearing light-colored clothing, such as whites, is advised to minimize attraction. Certain colors and wavelengths of light can significantly reduce mosquito presence in outdoor areas. While lighter colors do not repel mosquitoes outright, they are less attractive compared to darker shades.
Studies show that mosquitoes are particularly drawn to bluish and greenish lights due to their sensitivity to these wavelengths. Conversely, they do not like blue, green, violet, and white, with warmer colors such as yellow, red, and lighter hues being less appealing. Interestingly, lighter blues and purples are often ignored by mosquitoes because they reflect more heat and light, unlike darker tones.
It’s clear that mosquitoes aren't repelled by light in general. They are more attracted to infrared heat and carbon dioxide. Therefore, using strategic lighting choices, such as cool white or blue lights, may inadvertently attract them, while lighter colors like white, green, and blue are less beneficial in drawing them in.
Are Bugs Attracted To Light?
Insects exhibit varying responses to light, with many being particularly attracted to ultraviolet (UV) and white light. This explains why numerous bugs swarm around bright white fluorescent lights, whereas fewer are drawn to natural light sources like campfires. The primary reason for this attraction is the heightened sensitivity of insect eyes to UV wavelengths, making absolute light intensity less significant than the relative intensity compared to other light sources. Phototactic insects instinctively move toward or away from light; those swarming porch lights are positively phototactic.
Contrary to previous beliefs that insects are attracted to the heat of lights, recent research published in Nature Communications indicates that artificial light itself does not attract insects. Instead, the artificial glow disrupts their natural navigation, which relies on moonlight. This interference makes it difficult for insects to orient themselves, causing behaviors such as orbiting the light, steep climbing (stalling), and inverted diving over the light source. Artificial lights appear brighter and emit light in multiple directions, confusing insects' ability to determine up from down and scrambling their orientation to the horizon.
Additionally, insects approach light as a mechanism to escape predators hiding in darker areas like plant foliage. Instead of flying directly toward the light, insects tilt their dorsum toward it, resulting in flight patterns perpendicular to the light source. This dorsal light response often leads to insects becoming trapped near artificial lights once they approach closely. Most flying insects, including mosquitoes, flies, fleas, moths, and beetles, display this behavior. Studies consistently show that the attraction is not due to heat but rather the disruption of their natural light-based navigation systems.
What Insect Is Most Attracted To Light?
Flying insects such as beetles, termites, moths, flies, mosquitoes, grasshoppers, bees, wasps, and cockroaches are often drawn to light sources at homes. Studies indicate that while compact fluorescent lamps (CFLs) attract numerous bugs, light-emitting diodes (LEDs) attract significantly fewer insects. Many moths and other nighttime flyers use light for navigation, mistakenly associating artificial lights with moonlight, which they rely on for orientation. This behavior generates the familiar sight of insects swarming around light sources, particularly during the night.
The attraction of insects to artificial light is believed to be linked to both navigation and feeding, as flying insects may use visual cues to locate prey. Common insects attracted to light include moths, with studies noting specific interest from male saturniid moths towards UV lights. The attraction of various species like oleander hawk moths suggests that some insects are specifically drawn to light traps used in fields.
Popular theories regarding this behavior include "lunar navigation," where insects align themselves with light sources they perceive as moonlight, and the instinct to escape darkness. Consequently, both agricultural pests and various flying insects gravitate towards the brightness in residential areas. The most frequently encountered insect around light sources is the moth, though numerous flying insects are captured in these scenarios, influenced by their visual response to wavelengths emitted by artificial lights.
How Do I Make Sure LED Lights Don'T Attract Bugs?
To minimize bug attraction, opt for yellow and amber LED lights, which attract the fewest insects. In contrast, white and blue LED lights, along with ultraviolet (UV) and green LEDs, draw in the most bugs. Warm-colored LEDs (around 2700K) are less visible to insects, making it harder for them to locate the light source. To further reduce bug attraction from LED lamps that emit UV radiation, consider applying a coating that filters out UV and blue light. Research suggests that warm-colored LED lights are least appealing to bugs, while blue UV lights attract them the most.
If bugs are swarming around your lights, there are effective measures you can take. Brighter bulbs tend to attract fewer insects, as bugs are less sensitive to higher wavelength lights. Innovations like railing-mounted LED lights for porches not only beautify the space but also limit bug attraction. While some indoor lights are designed to attract insects, many LED options produce a warmer yellow-to-red light that deters them.
LED lights generally offer reduced insect attraction compared to traditional bulbs, but the color and heat they emit can influence insect behavior. For example, incandescent bulbs emit UV light, which attracts bugs. Choosing LED lights that do not emit UV and produce little heat can effectively keep bugs at bay. Entomologists recommend utilizing warm-toned LED lights to diminish insect presence while enjoying a well-lit environment.
Do LED Lights Attract Bugs?
CFL and LED lights draw fewer bugs compared to incandescent bulbs, which are notorious for attracting insects. Studies indicate that incandescent bulbs are highly inefficient for outdoor use, prompting some countries to ban them. While bugs are naturally drawn to light—a phenomenon known as phototaxis—research shows that warm-colored LEDs and specific bug lights are the least attractive, scoring about 4. 5 in attraction. However, the bug lights lured more of two insect orders than warm LEDs.
In general, while LED lights do attract bugs, especially those that emit shorter wavelengths and UV light, they are still less appealing than incandescent bulbs due to lower UV emissions. Bug attraction varies with LED types: white and blue lights tend to attract the most insects, while warmer high-wavelength LEDs are less enticing. Recent claims argue whether LED lights inherently repel bugs; opinions diverge among users and manufacturers. Regarding specific insect reactions, certain species like beach pillbugs are adapted to dim light, which may influence how they react to various light types.
In comparison, incandescent bulbs attracted the highest number of insects, followed by CFLs and cool-colored LEDs, while "bug lights" were the second most effective. It’s crucial to note that no lighting type is entirely bug-proof, as moths, flies, mosquitoes, and other insects may still be drawn to certain LEDs if they emit warm or UV-rich spectra. Although newer LEDs feature insect-repelling designs, the interaction with bugs depends greatly on the specific characteristics of the light used, such as brightness and color spectrum.
Are Spiders Attracted To LED Lights?
LED lights do not directly attract spiders; instead, they draw insects, which in turn attract spiders seeking prey. Spiders are not inherently drawn to the color or brightness of LED lights but are opportunistic predators that follow food sources like flying insects congregating near lights. To minimize the presence of insects and, consequently, spiders around property, switching to warm or yellow-toned LED bulbs is recommended, as these colors are less attractive to insects compared to bright white or blue LEDs.
Expert observations indicate that bright white and blue LED strip lights significantly attract insects and spiders, while red LEDs can deter spiders due to their longer wavelengths and lower attractiveness to prey species.
LED lighting has gained popularity for being energy-efficient and long-lasting. However, the choice of LED color spectrum plays a role in pest attraction. Some studies suggest that LEDs emit less heat and UV radiation than traditional lighting, potentially attracting fewer insects and spiders. Conversely, other research points out that since LED lights do not emit UV radiation, they can be more effective at attracting certain insects, thereby indirectly attracting spiders.
Spiders often position themselves near light sources to take advantage of the increased availability of food. While LED lights themselves do not emit UV rays, their brightness can still lure insects, making areas under or near LED lighting hotspots for spider activity. To reduce spider infestations, it is advisable to select LED lights with less attractive colors and to implement measures to limit overall light pollution around the property.
Nocturnal spiders may use light sources like LEDs to navigate and hunt efficiently. However, this behavior is not exclusive to LED lighting and can occur with any artificial light source. Additionally, some anecdotal evidence suggests that spiders might accidentally get trapped on LED strips due to minimal heat production and their placement in high areas, but this is not a widespread behavior.
In conclusion, while LED lights do not directly attract spiders, their ability to attract insects can lead to increased spider presence in illuminated areas. Selecting appropriate LED color temperatures and reducing light pollution can help manage and reduce spider activity around illuminated spaces.
📹 We Were Completely Wrong About Why Bugs Are Attracted To Lights
0:00 Bugs attracted to light 1:30 Previous assumptions that were not correct 2:50 New research and how it was done 3:35 …
in my research, i found that the actual nuclei of each cell would reorient toward the direction of the artificial light source, which would, of course, render the insect literally powerless to do anything but move in that direction…but, “in light” of this discussion, I’m now thinking that perhaps the cellular phenomenon may be responsible for drawing the insects near to the light whereas once they’re closer, this instinctual reorientation mechanism might basically “demagnatize,” if you will, the internal compass of each cellular nuclei. hmmm…
This phenominon, not only happen to insects, but also to fishes, squids, etc. in the ocean . By having a 1000 watts light bulb on, it has a pulling effect or attractive effect to the fishes, causing these fishes to stay near the light bulb . Some reason might be escaping from predators like sharks during night time as school of fishes will cast shadow which enables sharks to easily find school of fishes during night time . There are known nocturnal and diurnal activities of animals and insects . The shadow effect will push these school of fishes toward the said light, and so we say they’re attracted, but for some reason, there really are afraid of the predatorat ease on attacking them
One solution could be to use moving or alternating light sources, giving them a chance to leave the orbit. I often use a torch outdoors and because it moves faster than they can follow, it only alters their path for a moment, if they get too close. It wouldn’t be difficult to unstall 3-4 lights, a few metres apart, aimed at the same target, which fade in and out in a barely perceptible cycle. While it would have been very wasteful with traditional light bulbs, the energy cost for cycling LEDs is very low. Of course, it’s possible that they don’t mind and that it helps them to find a mate (if there are no spiders around and they haven’t used all their energy by the time they can escape…). All the same, it doesn’t feel like a nice thing to do, so I do my best to avoid using static outside lights.
This is a subject, not the insects, but light pollution, has bothered me for a long time. I’m 71 and when I was a kid, since air conditioning wasn’t widely used as it is now, we would often sleep outside in the backyard. It was fun but also much cooler than sleeping inside. I remember looking at the stars and being in awe at how many there were. Now, if I look up at the stars I really could count them. Only the brightest stars can be seen. I wonder how many young people have been outside in a place where they can see the stars. It is no wonder why the ancient societies we’re so much ahead of our folks today on astronomy.
Good study! This is similar to what I learned in the 1970s, that artificial light has rays going in all directions as opposed to the sun and the moon who’s light rays are parallel. Basically the insect tries to navigate to what it thinks are parallel rays, but they aren’t. This causes them to circle and spiral the light. It’s easier to understand with illustrations. The dorsal sensing is new and seems to fit well with the parallel natural light rays vs circular or omnidirectional.
As boys in rural Australia in the 1960s, we were taught by our male school teachers (we had male teachers in those days to teach us things that interested boys) and our scout masters and our fathers that insects such as moths keep the moon or a bright star in the top part of their vision and fly forward and under it so they could mate and lay their eggs far away from where they emerged from their pupa stage and thus disperse their offspring far afield. We were taught that the insects confused our lamps for the moon or a bright star and are keeping the lamp in the top part of their vision so they circle around it because it is close by, unlike the natural lights in the night sky which cannot be circled. We knew the insects were trying to fly straight but were confused and reflexively circling the light. We would use this to catch Bogongs and other large moths by putting a torch in a hole in the ground shining upward to cause large moths to flip over in flight and flop onto the ground where we could catch them. Now 60 years later these young “scientists” claim they have “discovered” why bugs seem to be attracted to lights and claim that my generation “were totally wrong”. We were not wrong; we knew all along. It saddens me that there is so much historical common knowledge and understanding that my generation had the benefit of, and which has not been passed on to this generation due to several decades of sociopolitical propaganda and indoctrination instead of good education.
What about the light being off for five minutes. I have seen moths sticking around and returning when the light is turned back on. This reason sounds suspect just because I have seen this too many times when the light is turned off. How do I know it is the same moth? Because it is inside my house where other openings are present so that the moth can escape when the light is off.
Richard Dawkins speculated in “The God Delusion” that something very similar to this (not necessarily about the light on the insect’s back, but about maintaining a constant angle to the light source for the sake of navigation and orientation) is the reason moths spiral towards flames. It seems that he was mostly correct.
This doesn’t explain why moths fly directly into a flame. I’ve spent a lot of time around campfires, and moths don’t fly around the fire in circles, they fly right into it. Sometimes their wings burn up before they reach the fire and they struggle with their last ounce of life to craw closer to the flames.
I’m blown away that people aren’t sure if insects are conscious. Of course insects are conscious (at some level). That’s why they have brains. That’s how they’re able to process their environment, find mating partners, find food, and escape threats. They’re not smart enough to figure out lights though.
I often enter forests at night (for work), and I use headlamps, sometimes normal light, sometimes UV. I swear I always get a flurry of moths crashing onto my face, my eyes, my mouth, my nose. With black light is even worse, hellish. So, I’m positive that they come directly towards the light, in spite of sophisticated scientific explanations.
I’m glad that we have a heat sensitive motion light on our porch. It means they aren’t getting trapped, because it doesn’t stay on for long at any given time (except Halloween night). I seem to recall having a different colored incandescent bulb years ago for my porch that didn’t attract bugs – yellow I believe. But I agree! It’s depressing. Like the army ants that get stuck in the scent trap circle and just go around and around and around until they die. Sad to have your instincts torture and possibly kill you.
Im still not convinced they’re 100% right. Did they see how many insects appeared in an unlit scene compared to a lit one? eg: if you leave the light on in your garage with the main door open in summer, it’ll quickly fill up with moths. But if the moths were trying to keep their backs to the light, how did all the moths get stuck in there in the first place. (they’d have to be heading toward the light until begining orbiting.) Still a firm believer that they’re using the moon for navigation, by keeping the moon in a particular segment(?) of their compound eye (kind of how i assume a bee navigates using the sun), and as they pass by the light source, they have to change their heading to keep it in the right segment. Would still explain all the observed behaviour, and how they came to be in close proximity in the first place.
Then why do moths fly into the dark during the day instead of flying around with their backs towards the sun. Can I live in Colorado where we have moths called Miller’s and they’re out by the hundreds of thousands. And when you disturb them during the day they don’t fly around with their sons to the back they get to somewhere dark.
One question I still have that this excellent explanation didn’t really address directly was: Why do sometimes they literally land ON the light and just stay there still staring into it for long spans(at least if the light source is not hot)? I’ve seen this a lot myself. But thanks for the article, nice to finally know the specifics as to their confusion.
I’m confused. Wasn’t the general hypothesis that they used light to navigate? This seems to be mentioned in books as far back as the 1800s, that light is used for orientation and navigation. For example, bugs do have eyes, and most are very photosensitive. So if you orient towards the brightest point, which is also, naturally open sky and the sun/moon, that is also a navigation cue, as well as orientation.
I once worked on a big building at a floor that had no closed windows (like a garage) and it had many tiny but powerful lamp reflectors. There was this particular day that a LOT of flies kept coming in, I’ve never seen so much. Almost like the entire neighborhood’s flying insects found their way into that building. Now seeing this article is crazy to imagine these little guys basically got pulled all the way up to the place on some sort of gravity equivalent force, having no choice. By the amount of flies i saw i believe they went there from distant, less bright places, just because of this innate mechanism. It’s like if we, humans, had to face a similar thing and got pulled not to the next room but a few streets farther just because of a big bright light thingy.
If it would be like you said then why mosquitos headbutts to my phone screen at night? Light attracts them because of these reasons; It is sooting and satisfying for their brain, it is even feeding for them in a way that kind of reducing the minimum limit of required energy and lastly it increases their lifespan by slowing down their aging processes. So, more light means less stress, less hunger and need of food and longer life for them.
Saya rasa kenapa mereka tidak terbang menuju bulan/matahari lalu memutarinya seperti yang terjadi pada cahaya buatan adalah karena jaraknya. Yang membuat ilusi bahwa cahaya bulan/matahari datang dari arah dan jarak yang sama dikarenakan jaraknya yang jauh. Seperti yang di jelaskan pada article mereka menggunakan cahaya untuk menentukan atas dan bawah, artinya ketika mereka mendapatkan cahaya yang datang dari arah dan jarak yang relatif sama mereka akan bisa terbang dalam garis lurus. Ingat disini mereka tidak menggunakan cahaya sebagai orbit mereka melainkan hanya untuk menentukan atas bawah. Nah hal ini pula yang terjadi pada cahaya buatan yang mereka terima dari arah yang selalu berbeda sehingga membuat mereka menyesuaikan atas dan bawah berulang kali, dan menyebabkan efek orbit.
