Does Light Keep Bats Away? (Quick Answers)

Do you know what keeps bats out of your house? You probably don’t, but you might be surprised to learn what does! Would you like to know why bats prefer dark caves? Darkness doesn’t appeal to them. 

The reason for this is that light scares them! Do all of those things exist or are they just myths? Come on, let’s find out.

Lights to keep bats away

Although light may deter some bats, there is not enough scientific evidence that it can keep them away from a home. Because bats confuse lights with night skies and other natural sources of illumination. Bright lights, however, reduce bat comfort in dark environments, causing them to flee.

In general, bats are nocturnal animals, which means they are active at night. Light exposure during the day can keep bats away from your home or office, even resulting in their demise. 

Light exposure not only disrupts their circadian rhythms but also causes them discomfort and eye damage. Keeping lights on at night when bats might be around is, therefore, a good idea.

Bright lights:

The best way to prevent bats from flying into your house at night is to avoid using bright lights when you are alone in your home. They tend to confuse these animals and can lead them away from the area if they get confused by them. 

Make use of low-light bulbs instead, or keep the evening light out of sight until the morning hours.

Outdoor lights:

You can also deter bats from your home by keeping your outdoor lights off during the nighttime hours. By doing this, they will be able to adjust their sleep schedule, and this may prevent them from coming into contact with humans or other animals in your house.

Red lights:

Red light doesn’t make a difference because bats don’t understand colors. As a result, if the red light is not bright enough, it cannot keep bats away. Red light cannot keep bats away from a house, according to scientific evidence.

Porch lights:

The use of porch lights at night can be one of the best ways to keep bats from entering your house at night. To find food, bats need to be able to see things from a distance, and porch lights can interfere with this ability because they interfere with their ability to see distant objects.

Using a light that is not too bright will help you to discourage bats from visiting your residence by making it as dark as possible.

Strobe lights:

Using strobe lights is one of the most effective ways to deter bats from an area. Due to these pulses of light, a lot of noise and disruption can be produced, which may scare away the animals. 

In case you have not been able to solve your problem via other methods, you should use strobe lights as a last resort.

LED lights:

Using LED lights can help keep bats at bay more effectively than using traditional light bulbs. Their use of less energy and less likelihood of causing eye damage or discomfort are both advantages. 

For areas with bats, such as kitchens and bathrooms, LED lights are the best choice for illumination.

Are bats attracted to light in attic at night time?

Bats are not attracted to light in the attic at night time. Generally speaking, bats avoid light whenever possible since they are nocturnal. In this case, both indoor and outdoor lighting might be blowing through an attic window at night.

In contrast, some people may believe this because they have heard stories or watched movies about how lights and windows at night soothe and calm them.

In fact, there are several reasons why bats might be attracted to light in an attic at night. It may be related to feeding behavior, as bats use echolocation (a process in which they send out acoustic waves) to find food. 

They may be searching for prey by detecting faint echoes of sound near LED lights or other electronic equipment outdoors on a dark day to navigate dark spaces and avoid obstacles.

Why do bats avoid light?

The bat is a nocturnal animal, which means that it lives and hunts at night, which means that it is predominantly nocturnal. Thus, they have evolved in a way that allows them to be particularly sensitive to light levels as a consequence. 

There are several reasons why bats tend to avoid light, but here are the most common ones.


For navigation and finding food, bats use echolocation. Since their eyes cannot see clearly near sources of light, they can’t use this ability as reliably.

Light disrupts bat behavior:

The presence of artificial light disrupts the behavior and communication of bats. When bats are exposed to bright lights, their flight patterns change and some species even stop eating! 

Artificial light interferes with the wavelengths of sound that bats use for communication, navigation, and hunting due to its interference with wavelengths of sound.

Light scares bats:

A bat is easily scared, which is one of the main reasons why he avoids light in the first place. Light from artificial sources can cause them to flee or even become agitated and hostile when they see artificial light.

Bright lights don’t suit their eyes: 

Light in the near-ultraviolet range is particularly sensitive to bats since they don’t have good eyesight. For this reason, bright lights can be so disruptive for them, which is why they prefer dark places to live.

How to keep bats away with lights?

Bats are beneficial pollinators and predators, but if you live in an area where bats frequent, you may need to use lighting to keep them away. The following is a guide on how to keep bats away with lights.

Install automated dusk-to-dawn lighting:

The first step is to install automated dusk-to-dawn lighting. It will keep bats at bay by providing a consistent light source during twilight hours when they are most active.

Position lights in locations:

Another option is to position lights in locations where they are not likely to be disruptive. For example, try positioning them near trees or other features that bats might use for shelter.

Use low-intensity light bulbs:

When installing lighting outside, it is a good idea to choose low-intensity light bulbs. By doing so, we will be able to minimize the impact on bat behavior and allow them to continue using their natural navigation abilities.

Use motion detectors:

You can use motion detectors or other sensors to activate lighting when a certain amount of activity is detected. Several lights, including floodlights, can be set to turn on automatically when movement is detected, such as those with a floodlight function.

What keeps bats away at night?

The echolocation of bats allows them to navigate through their surroundings. The best way to keep bats away from your home is to take a few simple precautions. The following are the most effective ones.

Visual Deterrents:

Visual deterrents such as bat-proofing your windows and installing a widescreen or window film are effective in keeping bats away from your home. In this way, you will be able to prevent them from entering your home when they are seeking food or shelter in your home.

Physical Deterrents deterrence:

You can also use physical deterrents to discourage people from entering your home, such as baffles or spikes attached to the walls and roof of your house. 

By using these types of bat repellents, you will be able to prevent bats from roosting near your home or from entering it through vents or other openings.

Sound Suppression Devices:

A sound suppression device can also deter bats. The bat repellents work by emitting a sound that is unpleasant and unwelcome to bats, causing them to flee away from the area. 

A wide variety of sound suppression devices are available on the market today, so be sure that you select the one that best suits your requirements, as there are several types of sound suppression devices available today.

Charismas Lighting:

Using Christmas lighting is another way to keep bats away from your home. UV and electronic light are used to deter bats from approaching or flying near these lights. Due to their effectiveness at repelling bats, they range in price from $50 to $1,000.

Light reflective materials:

As a last resort, you can use materials that reflect light to keep bats away from your home. There are many ways to accomplish this, including installing brighter lights or covering your exterior with a layer of reflectors that will make your house appear brighter.

Final Thoughts

Briefly, light can discourage bats from flying near your home. Physical deterrents and Visual devices are also effective methods of preventing them from entering. A sound suppression system is one of the most effective deterrents to bats to keep them away from buildings at night.
