We have all faced the massacre of tiny flying bugs inside our homes. Especially during the monsoon season, these bugs will make their place around the light and will stick to it. Annoying, isn’t it? But have you ever thought about what these tiny flying bugs in the house attracted to light and what you can do about them? Let us find out.

Why are flying bugs attracted to light?

Bugs, particularly flying bugs, are often attracted to light. Scientists have not been able to figure out why this is the case, but they’ve come up with a few theories.

One popular theory is that they mistake the light for the sun or some other natural source of light. Another theory is that the light attracts them because it means there is an opening in whatever structure they are trying to get into.

Despite scientists’ efforts, the reason why flying insects are drawn to light remains a mystery. Some tend to believe that it has something to do with the insects trying to navigate their way home, while others think that the light confuses the bugs and makes them easier to catch.

No matter the reason, it’s clear that many flying bugs are very drawn to lights!

Let us take a look at some prominent reasonings given by researchers,

Bugs use light to navigate.

Bugs use light to navigate their way around. This is especially true for nocturnal insects who use the light from the moon and stars to help them find their way. Some bugs are even attracted to artificial lights, like those in houses, because they confuse light with natural sunlight.

When they are near an artificial light source, such as a lamp, they can become confused and disoriented. This is why you often see bugs flying around lamps or near windows-they are trying to find their way out.

This is especially true for insects that are attracted to light, like moths and fireflies. Porch lights are a common source of bug confusion because they can be mistaken for the sun or stars.

Bugs are trying to find food.

Moths, which are known to feed on the nectar of flowers, are attracted to flowers because of their ability to reflect ultraviolet (UV) light.

Because certain light bulbs emit a trace amount of UV light, it is possible for flower-seeking insects to confuse a bulb for a flower if they are exposed to it.

Insects Are Making Attempts to Evade Their Predators

Another idea as to why insects are drawn to light proposes that in the natural world, light acts as a beacon directing insects away from potentially harmful situations.

It is possible for insects to deduce from the presence of light that a passage is not being obstructed by a predator or other impediments.

This might explain why insects and other pests fly directly into light sources, seeming to smash into bulbs and lanterns without their knowledge.

Looking for Something to Eat

Lastly, some people think that insects are drawn to porch lights and campfires because they are aware that other insects are also drawn to these things. It’s possible that these animals are either hungry predators or suitors on the prowl for a potential partner.

The question now is why it is that insects are drawn to light. The reality of the problem is that we do not now possess a straightforward response to the question that was posed. These hypotheses will have to suffice for the time being!

Why Are There Flying Bugs In My Light?

The vast majority of insects are very attracted to bright lights and places that are kept at a comfortable temperature.

As a result of this, it is typical for there to be a significant increase in the number of insects throughout the summer months. Some of the most noticeable insects at this time of year are mites, ticks, fleas, and moths.

However, due to the fact that all insects possess something that is known as phototaxis, many different pests may enter your house. And this is exactly why insects will rush to any area where there is a source of light as soon as they see it.

When it comes to insects, artificial light is the equivalent of the sun, and they utilize it to navigate their flight paths.

Because of this, there are quite a few insects in the surrounding area, particularly in the lights that are left on the patios.

Why do flying bugs use light for safety?

A strong light source may be seen as an emergency signal by certain insects. When in doubt, these insects immediately seek light sources that are often located on higher ground than the dangerous area they are presently in.

Light serves as a known safety signal for certain insects, much as air bubbles guide some submerged organisms to the water’s top.

How do flying insects utilize light to navigate?

Another prominent explanation for light attraction is that insects utilize it as a navigational aid. An insect traveling north, for example, may estimate its direction by maintaining a natural source of light on its right, such as the sun or moon.

This strategy works effectively as long as the light source is continuous and at a distance. When an insect comes into contact with a spherical incandescent porch light, it gets perplexed by its source.

This explains why a moth would constantly round a light source – it intuitively seeks to retain the light on one side of its body while navigating its path.

What is phototaxis?

Phototaxis refers to the difference between insects that are drawn to light and those that are not. Certain insects, such as cockroaches and earthworms, exhibit negative phototaxis, which means they are repulsed by light.

Moths, flies, and a wide variety of other flying insects exhibit positive phototaxis and are naturally drawn to it.

The scientific controversy over a flying bug’s affinity to light

The scientific community is divided on why a positively phototactic creature, such as a fly, would continue to linger near an artificial light source even when natural light becomes accessible.

Some feel that the bug is drawn to the darkness around it rather than the light itself.

Others contend that the insect’s eyes, which often have many lenses, fail to shift from light to dark, leaving the insect susceptible to predators while night-blind.

In this instance, the insect may decide that staying in the light is preferable to flying away and becoming too blind to respond to dangers and obstacles.

Why are flying bugs drawn to LEDs?

For many years, we have been persuaded as homeowners that LED lights are a better, more energy-efficient method to light our houses.

Furthermore, LED technology generates light in a unique manner, producing UV-A as powerful beams of light that penetrate deeper into the surrounding area than light phosphor lamps, for example.

House flies, in particular, are able to perceive and are drawn to UV light, which humans cannot see. We don’t utilize UV light in our buildings or in our surroundings since we can’t see it.

This implies that any UV light utilized in urban structures would glow like a beacon, making UV light traps very effective: they will stand out as the strongest source of UV-A light in the human habitat.

Efficacy of using light to destroy flying bugs

Various researchers can demonstrate the effectiveness of LED-powered fly killers using a conventional Half-Life measurement technique.

The half-life cycle reflects the time required to eradicate 50% of the flies introduced in a test chamber. The shorter the Half-life, the more efficient the insect light trap.

However, a successful fly control scheme must also include the location of fly trap devices (given what we know about phototaxis). The location of fly killer units in relation to local light sources is crucial to fly control efficacy.

What are these tiny flying bugs in the house attracted to light?

The most vexing insects can be kept at bay; nevertheless, you must be constant with your efforts. There are several particular insects that you can identify quickly and eliminate by following the appropriate steps:

Fruit flies

These insects will come without your notice and will not hesitate to visit the area where you have ripening fruits or vegetables.

The fruit fly may enter your house via open windows, doors, or gaps. A mesh might be of great use in protecting you from the grotto fly and other pesky insects.

To get rid of fruit flies, clean the breeding area using a dish soap and water combination. This combination is highly successful, and once you start using it, you should be able to eliminate all the fruit flies around you.

The drain flies

This bug is also widespread in houses, and its dark look might be confused with mold. Drain flies enjoy damp environments and may readily spawn in drains. As a result, your sink or shower drain might be an excellent area for this bug to dwell peacefully.

Drain flies multiply fast, and essential oils may help you get rid of them quickly. Clean your home’s drains with the essential oil of your choosing, and you should be able to get rid of them.

Green flies

Because of their color, these flies are among the most repulsive, but the good news is that they are not very fond of residing inside. Green flies, on the other hand, may bite as well as black flying insects.

How to keep bugs out of the light fixtures?

Outdoor bugs on your external lights? Here’s how to manage them.

Here are certain suggestions for keeping pests away from your garden lighting.

The simplest method is to utilize different lighting. Replace the light bulb with a yellow light bulb, which is known to repel insects.

Though the light emitted isn’t the most appealing, it has been shown to repel pests.

Use garlic

Garlic repels numerous flying pests and may be applied straight to most lights.

One tablespoon garlic juice plus six teaspoons water Fill a spray bottle halfway with the mixture. Then, right onto the light cover, spray it.

Avoid getting any inside the light bulb or socket since this might cause an electrical danger. Keep an eye out for electrical outlets. The goal is to fully coat the light guard with garlic spray. The remedy will keep bugs at bay for a long period.

When you detect bugs forming on the light again, you’ll need to reapply.

Use citronella lights or candles.

Citronella is natural houseplants extract that may be quite effective for outdoor insect control. These are naturally occurring chemical that repels bugs.

This is a natural mosquito and flea repellant that is widely available in supermarkets. Citronella is used in a variety of products, including candles, flame torches, and lighting. Use whichever method works best for you.

Citronella has a pleasant minty fragrant perfume that is pleasing to people yet repulsive to pests. This may help deter bugs from your porch light or serve as a replacement.

Plant marigolds

Marigolds are one of several effective insect repellent plants. If you live in the appropriate USDA hardiness zone, you may grow marigolds. The aroma of the plant repels many flying insects.

Clean up your yard

Clean up any recyclables or receptacles that may have accumulated near the light. Good yard upkeep is essential for keeping your yard free of a variety of pests. This entails doing the following to maintain your yard tidy:

  • Clear the clutter
  • Organize tools, outdoor furniture, BBQs, and other items.
  • Remove any leaf litter.
  • Plants should be pruned.
  • Compost containers that are secure
  • Keeping bugs out of woodpiles
  • Drain maintenance
  • Upkeep birdbaths and feeders
  • Pet or bird food storage
  • Cleaning the gutters
  • Upkeep of water features or fountains
  • Timely harvesting of fruits and vegetables

You’ll be astonished at how much pests will be reduced just by taking excellent care of your garden.

Remove water sources

Water sources should be eliminated. Leaving water offers a supply of moisture for pests such as pill bugs, mosquitoes, and pincher bugs. They may also serve as a bacterial breeding habitat.

Outdoor pests should never have access to stagnant water. For most folks, this is a simple repair.

To control vectors, try introducing natural predators that consume insect larvae found in water to birdbaths, fountains, pools, or other water features.

You may also clean birdbaths on a regular basis to prevent the spread of germs and pests. Because flying bugs can reach the bath, they utilize it as a source of food source and breeding habitat.

You may use mosquito repellent products in fountains and even add predators such as minnow fish. Pool bugs and other vectors may be kept at bay with frequent shock treatments.

Use a false light

If you can’t get rid of the insects that congregate around your home’s exterior lighting system, try utilizing light to entice them away.

Set up a strong spotlight or mounted light away from essential places such as your porch, windows, and doors.

Bugs may be lured to this strong source of light instead of the lights near your home’s entry point.

Essentially, the bright light serves as a decoy to keep bugs away from your house in an effort to keep them.

Fewer bugs in your lamp shades equal fewer pests in your house. Use a solar-powered light source to conserve energy and make this a green approach.

This makes it simple since you won’t have to deal with cables or electrical connections, and you won’t have to pay more on your monthly power bill.

Isn’t it cool?

Remove organic matter

Mayfly are flying, playing around the fluorescent lights.

The last step is to remove any organic stuff from surrounding your patio lighting.

This includes clipping leaves, clearing trash and litter, and cleaning up any foliage that has fallen to the ground. Flying pests eat on garbage, compost, grass clippings, and other vegetation.

They utilize them as a breeding site, and since they are near to your lights, don’t be shocked when they hatch and are attracted to your decorations.


So now we are well aware of not just all the tiny bugs that come into our house seeking light but also the best methods to restrict them from entering our house.
