You’re in for a surprise if you’ve ever thought that bats are silent and exclusively communicate in quiet.
When I spotted a newborn bat one evening and looked after it for a few weeks, I definitely learned that bats can be pretty noisy.
Despite the fact that humans don’t often hear them, bats are actually capable of making a variety of noises.
What Does a Bat Sound Like?
Most bats utilize their vocal cords and larynx to generate calls during echolocation, much like how people use their vocal cords and larynx to talk.
Although different bat species have distinctive cries, clicks are the most common way to characterize bat noises. However, when these noises are slowed down, they resemble the chirping of a bird and take on notably distinct tones.
Some bats generate calls entirely without the use of their vocal chords; instead, they click their tongues or exhale sound via their noses. Other bats use their wings to create clicks.
It’s interesting that there is ongoing discussion over the precise mechanism through which bats click their wings. Uncertainty surrounds the source of the noise, which may come from the wings smacking together, the wings’ bones shattering, or the wings slapping on the bat’s body.
Do Bat Noises Sound Like Scurrying?
The answer to the key query, “Do bat sounds sound like scurrying?” is no. If you’ve been hearing scurrying noises, it’s doubtful that you have a bat infestation because bats utilize flying to get around. However, these sounds might be coming from a variety of creatures.
When dealing with bats, the most frequent sounds you’ll hear in a wall hollow are scratching and flapping wings. All the fauna that is frequently seen in homes is silent, but bats are by far the quietest.
On rare occasions, a bat will become stuck in the wall and create a lot of noise as it scrambles to get out. You will need to rely on visual proof to determine the existence of bats in all other circumstances save these singular instances.
Ultrasonic Sounds of Bats
Bats use their larynx, nostrils, vocal cords, tongues, and wings to produce ultrasonic sounds.
Depending on the species, bats may employ all of these techniques or just one, but they always create ultrasonic noises with echolocation in mind. Bats are better able to see this way.
Even while you may think that bats are, well, as blind as a bat, this isn’t always the case. Even though they have poor eyesight, certain bats can see.
When I delivered the bat pup, or young bat, his food, he was perfectly capable of seeing my hand and could navigate his environment without the use of echolocation.
However, most bats use echolocation, which allows them to focus on a specific item that their sound waves reflect off of. A bat won’t just fly into anything, which is why.
Bats can really hear where they are going.
The normal ultrasonic noises that bats use to fly and hunt are not what we hear in our houses where bats have established nests.
Instead, the sounds created by the bats moving various body parts are what I would refer to as chittering, chirping, shrieking, and scraping.
When another bat approaches a mother’s pup too closely, they shriek, scrape along the ceiling boards, and may even fight over a perch. It’s loud in a bat colony.
What’s Making the Scurrying Noises?
It’s likely a tiny animal has entered your home if you hear scurrying sounds. Rats and mice, for example, often produce scurrying noises and are most active at night.
Late at night, when there is a greater concentration of scurrying, mice or rats are most likely active. You might note that the sound of scurrying is often followed by the sound of scratching or nibbling since they have a tendency to chew and scratch quite a bit.
Squirrels are another animal that could cause noise in your house. Compared to mice and rats, squirrels tend to make more noise, especially when they are moving about in search of food. Squirrels may be the source of the noise if it seems like they are scurrying about potential entrance points in particular concentrations.
The time of day is another excellent indication. Squirrels follow similar hours to humans, so you’ll typically hear them around dawn and evening. When there is no movement in the house, such as in the middle of the night, rodents are more likely to be active.
How to Record Bat Sounds
Bat detectors can hear the noises that bats emit even while humans cannot. These detectors have specialized microphones that can record ultrasonic noises and circuitry that can convert the sound so that it can be heard by humans.
These bat detectors employ the following techniques to capture sounds:
Heterodyning combines an incoming bat sound with a frequency that is comparable, creating a “beat” that people can hear.
As was previously mentioned, the noises made by bats have frequencies that are two to three times higher than the maximum range of human hearing. In order to make the bat’s sound audible to humans, frequency division detectors multiply the sound by ten.
Time expansion: More frequent events happen more often. Time expansion detectors often also slow down an approaching bat sound by a factor of ten such that it is audible to humans.
How Can I Tell If I Have Bats?
Bats identify food sources and communicate with one another by using echolocation. The noises produced by echolocation sometimes resemble a string of high-pitched clicks or chips. The noises that bats produce are really a few octaves above the range of human hearing.
In the open air, you wouldn’t be able to hear the sounds at all, but when bats enter your home, the insulation and the small spaces they often inhabit amplify the noises they make.
However, bats are still comparatively silent. Even if there are bats in your house, you probably won’t hear them very often. Bats occasionally produce additional noises in addition to this succession of high-octave clicks or chirps, which is the sound most commonly associated with them.
You could hear fluttering and scratching noises if they become stuck within a house’s walls or in the attic. These noises indicate that the bat is attempting to flee and is probably in trouble. A bat is more likely to lash out if it is in distress if you make an attempt to make physical contact with it.
Since rabies is spread by physical contact, physical contact with bats should always be avoided. However, it’s crucial to avoid physical contact with bats in circumstances when the bat could be in distress. Call a wildlife removal service immediately away if you think you have a bat stuck in your ceiling, attic, or walls.
How to Quiet a Noisy Bat Colony
Personally, I enjoy listening to the little bat colony that lives in my attic area. Although their gentle chittering and scratching are barely disturbing, I am aware that many people find the noises of bats in their houses to be unpleasant.
It is important to remove the colony and contact a pest control company. However, bats are crucial to the ecosystem and are required to keep insects and other pests like mosquitoes under control.
Take precautions to muffle noises before you eliminate the neighborhood bats. To keep your sleeping area away from the bat colony’s nesting location, you can add soundproof insulation, relocate furniture to block sound, and rearrange your bedroom furnishings.
You may completely avoid hearing bats in your house with simple preparation.
What should you do if you find bats in your attic?
Bats are useful animals to have around, but having a colony in your attic may be very problematic. They stink, their droppings contain a fungus that can lead to histoplasmosis (a kind of fungal pneumonia), a buildup of guano in your attic can lead to structural damage.
Bat removal is a little more difficult than typical pest control work. This is mostly due to the fact that it is prohibited to harm or kill bats since they are a protected species. Additionally, it is illegal to harm their ecosystems. What should you do, therefore, if you discover bats in your attic?
Exclusion doors, which are essentially one-way exits, could also be installed. Any leftover bats will utilize them to exit your attic, but once they are outside, they won’t be able to get inside again.
How Bats Hear
Contrary to popular belief, which holds that bats just pick up on their own ultrasonic sound waves, the truth is far more nuanced.
Baby bats can pick up on the tone and intonation of your voice, I quickly learned while caring for the bat pup I had rescued. When I called, the bat pup would become happy because he knew it meant food.
He could tell where the delicious pieces I was giving him were by yelling at me.
A bat can hear its own sound echoes despite the surrounding cacophony of a bat colony, much as how hearing your name will draw your attention in a busy environment. They choose the music they listen to.
Bats are capable of hearing both the surfaces from which their own sound waves have reflected and those of other bats.
This gives them the ability to hear what is directly in front of them (as if it had their name on it), where their next meal is flying, and whether there is anything in their way.
What to Do?
The best course of action if you hear scurrying noises is to call a wildlife removal agency right away. Technicians that provide wildlife removal services are educated to identify the species of animal that are present in your property.
They will be able to identify the type of animal you have concealed within your home after doing a fast examination of your living area. They will also be able to quickly and effectively remove the animal or animals. The only people qualified to remove bats are experts.
Frequently Asked Questions about What Bats Sound Like
Describe the sound a bat makes.
Some bat noises are generated at a volume that is audible to humans and is at the lower end of the ultrasonic range. Most of the time, bat sounds fall outside of the range of human hearing.
Therefore, even though you might hear some bat squeaks, you won’t hear all of these noises unless you use an ultrasonic microphone and lower the speed to a level that is audible to humans.
What noises terrify bats?
You may take advantage of the fact that bats communicate through ultrasonic sounds to persuade a colony of bats to leave your roof, where they may be roosting.
You may communicate with them in their own sounds by playing ultrasonic noises to them. Bats will soon leave the area since they dislike other ultrasonic noises and might become confused by them.
How can bats avoid being deaf in the presence of noise?
Ultrasonic sounds are all around bats all the time. A single shriek from a bat may generate a noise pressure of up to 100–110 dB. Therefore, it seems sense that bats would eventually lose their hearing if they were surrounded by hundreds of other, similarly loud bats.
Bats, meanwhile, have absolutely no hearing loss. Bats never have noise sensitivity, even though they can continually see via their ears.
Using their vocal cords, larynx, tongues, noses, and, in certain circumstances, wings, bats produce a succession of clicks. Using a technique called echolocation, they utilize these noises to find prey, objects, and other bats in their surroundings.
Although bat calls have a high frequency that is outside the range of human hearing, humans may use tools called bat detectors to listen in on their talks.
