6 Effective Ways to Scare Rats Away with Sound

Scaring Rats Away with Sound: A Guide to Repelling RatsRats are one of the common pests that can invade your home and cause significant damage. They can gnaw through wood, electrical wiring, and insulation, leaving you with costly repairs.

Worse still, they can transmit diseases such as leptospirosis, rat-bite fever, and salmonellosis. To prevent these destructive and dangerous rodents from finding a home in your property, you can use sound as a deterrent.

In this article, we will explore the effectiveness of various sounds in repelling rats and the reasons why you should keep them away.

Methods of Scaring Rats Away

Rats have sensitive ears and can detect sounds in the ultrasonic range that humans cannot hear. While sudden loud noises can startle them, they can quickly habituate to repeated noise.

Here are some of the most effective ways to use sound to scare rats away. 1.

Stomping Feet, Yelling, and Clapping

Rats have a natural fear of animals, especially humans. Loud and sudden noises that mimic the sound of predators, like stomping your feet, yelling, or clapping, can scare rats away as they perceive the area as unsafe.

These techniques work better when used in conjunction with other methods such as trapping, sealing gaps and holes or using repellent sprays. 2.

Machinery Sounds

Rats can also be scared away by machinery noises such as leaf blowers or lawn mowers. These sounds mimic the vibrations generated by a predator such as a dog or cat, and can cause rats to flee.

3. Pet Sounds

Rats are afraid of pets, especially dogs and cats.

Therefore, playing recordings of pet sounds such as barking or purring can scare them away. It is important to note that this method is more effective when the pet sound is combined with other deterrence methods.

4. Pots and Pans

Rats are sensitive to vibrations and high-frequency sounds.

The banging of pots and pans or other metal objects will create both a loud noise and strong vibrations that can scare rats away. 5.

Ultrasonic Devices

Ultrasonic devices designed to deter rats produce sounds in the ultrasonic range that humans can’t hear. These devices can be powered by batteries or electricity and emit ultrasonic waves that can disturb the rats’ nervous system, causing discomfort and making the area inhospitable for rats.

6. Noisemakers

Noisemakers such as air horns or hand clappers are another effective way of scaring rats.

They produce sudden, loud noises that startle the rats. However, like most of the methods listed above, they work best when used in combination with other techniques.

Effectiveness of Sound in Repelling Rats

The most effective way to use sound in repelling rats is to combine it with other methods such as sealing gaps and cracks, eliminating food sources and habitats, using traps, and chemical repellents. Here are some factors you should consider when using sound to repel rats.

1. Sudden Loud Noises

Sudden, loud noises such as whistles or foghorns can scare rats away temporarily.

However, you should use them in combination with other methods, as rats can quickly habituate to repeated noise. 2.

Rat’s Sensitivity to Sound and Touch

Rats have an acute sense of hearing, which they use to communicate with each other, navigate their environment, and detect predators. It is important to note that contrary to popular notions, rats are not attracted to cheese; they rather prefer food sources with a high-fat content like meat, fish, and nuts.

3. Habituation

Rats can quickly habituate to repetitive noise.

Therefore, it is best to change the pattern of the noise you are using to repel them, or combine different sounds to create a variation. Also, rotate the sound-producing device’s location regularly to prevent rats from adapting.

Reasons to Keep Rats Away

Apart from the unpleasant experience of having rats in your property, there are several reasons why it is essential to keep them away. 1.

Damages Caused by Rats

Rats can cause significant damage to your property. They can gnaw through electrical wiring, pipes, and insulation, leading to costly repairs.

They can also damage wood and cause damage to the foundation of the house. Rats can contaminate food products with their urine and droppings, making them unsuitable for consumption.

2. Health Risks

Rats are known to transmit a range of diseases such as leptospirosis, a bacterial infection that can cause kidney damage and meningitis in humans.

Rat-bite fever is another disease transmitted by rats; it is a potentially deadly bacterial infection that can cause fever, vomiting, and rash. Salmonellosis is a foodborne illness that can be caused by consuming food products contaminated by rats.


Scaring rats away with sound can be an effective way of deterring rats from your property. Rats are sensitive to vibrations and high-frequency sounds, and sudden, loud noises can frighten them away temporarily.

However, to use sound as a lasting method of repelling rats, you should combine different types of sounds, change their location regularly and use them alongside other methods of repelling rats, such as sealing entry points, eliminating food sources, and using chemical repellents. Remember that rats can cause significant damage to your property and transmit dangerous diseases, so you should take immediate action when you identify a rat infestation in your property.

3) Other Ways to Keep Rats Away

Scaring rats away with sound is just one way to keep them away from your home. There are additional methods that can be effective in repelling rats.

Let’s look at two of those methods.

Making Your Yard Unattractive to Rats

One of the best ways to keep rats out of your home is to make your yard unattractive to them. Create an environment that is uninviting to rats by eliminating wherever possible, their sources of food, water, and shelter.

Hiding Places: Rats are opportunistic feeders, seeking food from trash and pet bowls. Keeping trash cans tightly sealed and cleaning up pet excreta immediately can reduce the attraction for rats.

Rats seek out secure, enclosed spaces to seek shelter and nest. Clearing yard enclosures and piles of debris will reduce the likelihood of them developing a comfortable home.

Attractants: Rats are attracted to open garbage cans and uncovered piles of wood or debris. Removing organic matter, such as fallen fruit from trees, from your property can reduce the attraction for rats.

Elimination of Hiding Places: Tall grass and thick vegetation provide hiding places for rats. Mow the lawn regularly, trim shrubs and hedges, and keep tree branches well above the roofline of the house.

By eliminating potential hiding places for rats, you reduce their opportunities to enter the home.

Blocking Entryways

Rats can enter your home through small cracks and holes in walls or roofing. Rats can access your home by following electrical and utility wires into the house through gaps that should have been caulked.

Addressing these vulnerabilities can prevent rats from entering your home. Sealing Gaps: Check for gaps in walls, roofing, or window frames.

These openings provide entry points for rats into your home. Sealing gaps with steel wool and copper mesh or caulking small cracks in walls can keep rats out.

Repairing Broken Fixtures: Rats can enter through broken seals around pipelines, so make sure all pipes are properly sealed.

4) The Debate on Ultrasonic Devices

Ultrasonic devices emit high frequency sound waves that are supposed to repel rats and other rodent pests. However, their effectiveness in repelling rats is a topic of debate.

Here are some factors to consider before purchasing an ultrasonic device.

Effectiveness of Ultrasonic Devices

The effectiveness of ultrasonic devices in repelling rats is often disputed. While some companies claim that their ultrasonic devices are effective in keeping rats and other rodent pests away, there are mixed reviews on their effectiveness.

Studies on ultrasonic devices have shown that there is little evidence to suggest that they are more effective than other methods of repelling rats. One reason why ultrasonic devices may be less effective is that rats may become habituated to the sound waves.

Habituation occurs when the rats are exposed to the same sound repeatedly, and the sound no longer affects them. Scientists believe that rats may perceive the sound waves as background noise, causing the rats to ignore the sound.

Another issue with ultrasonic devices is that they are directional. They emit sound waves in a particular direction, so rats can avoid them by simply moving in a different direction.


Preventing rats from invading your home requires a combination of methods. Using sound as a deterrent is useful, but should be combined with other techniques such as sealing gaps and holes, removing attractants, and blocking entryways.

Ultrasonic devices have been marketed as a solution, but their effectiveness in repelling rats is a matter of debate. Therefore, you should consider other methods before relying on ultrasonic devices.

By following the methods outlined in this article, you can keep rats out of your home and protect your property from the damage and health risks associated with infestations. In summary, protecting your home from rats is crucial to avoid property damage and health risks.

Although sound can be an effective way to deter rats, it is best to combine it with other methods and take several preventive measures such as eliminating attractants, sealing potential entry points, and removing hiding places. The effectiveness of ultrasonic devices in repelling rats is a matter of debate and should be thoroughly researched before relying on them.

By implementing these techniques, you can successfully keep rats away from your home and prevent costly damage and infectious diseases.
