Do Ultrasonic Pest Repellers Work On Roaches? Roach Solution

Pests such as mice, rats, and roaches are known to be a great threat to any household. They cause damage to property as well as spread diseases. Maintaining the cleanliness of your home is essential to keep these pests away.

However, this may not be enough to get rid of a roach infestation. In that case, you’ll need to pull out the big guns.

Ultrasonic pest repellers are a common sight in American homes. They promise to drive away pests such as mice and roaches with high-frequency sound waves inaudible to humans. So, do they work? Let’s find out.

Do Ultrasonic Pest Repellers Work On Roaches?

Ultrasonic pest repellers are ineffective in roaches while highly effective in repelling crickets. While roaches can hear ultrasonic frequencies, they do not appear bothered by them. 

The sounds emitted by these devices irritate the cockroach’s ear canal, which may then force them to leave. However, some experts believe that only certain roaches respond to this device.

Ultrasonic Pest Repellers 

Ultrasonic pest repellers are devices that emit high-frequency sound waves, which cause pests to leave the area. 

The sound waves are usually out of the range of human hearing, and most pests will flee when they hear them because they are not used to the frequency. 

These devices are safe and eco-friendly. Aside from being safe for people and pets, it’s also safe for plants and animals outside of your home.

The pests are usually attracted to materials such as metals, wood, or water. Ultrasonic pest repellers prevent these pests from getting near such materials. This can be effective for repelling mosquitos, mice, rats, flies, roaches, and fleas. 

Cockroaches are not fans of longitudinal sound waves. Sound waves are longitudinal waves that produce vibrations when they move through a medium. 

Cockroaches become used to sound and are more sensitive to longitudinal sound waves produced by movements, such as vibrations and music woofers. 

Different waves exist, including transverse waves (think of the ocean) and electromagnetic waves (think of lasers). Sound waves are measured in hertz.

A higher frequency will result in a higher pitch of the sound. For example, humans can hear a bird chirping at around 5 kHz, while the range for cockroaches goes from 20 Hz to 100Hz and are very sensitive to these frequencies.

What Time Are Cockroaches Most Active?

Cockroaches are nocturnal animals, which means they’re most active at night. Roaches typically stay hidden during the day but venture out at night searching for food and water.

Pest control experts recommend that homeowners leave a few lights or small lamps on in the kitchen overnight. Cockroaches dislike exposure to light, so keeping a couple of lights on will help keep them at bay.

What Is The Lifespan Of A Cockroach?

The life span varies by variety, and they can live for up to 20 to 52 months(1 year). A cockroach’s life span is influenced by the amount of food available, temperature, and humidity level.

Did you know that roaches have been around for more than 300 million years? That makes them far older than humans, who have only been around for 200,000. That’s a lot of time to evolve, and they’ve become pretty good at surviving in their environments.

Roaches are such a successful species because they can adapt to their environment. They’ve lived through some of the worst mass extinctions and geological upheavals, including the global ice age. They are the hardest creatures to kill.

Where Do Roaches Hide In The House?

Roaches are the scourge of many homeowners and are quite difficult to control. They are a nuisance and a health risk. Cockroaches reproduce quickly and can infest an entire home in a matter of weeks.

It helps to know all about your enemies and their weakness in battle. To get rid of roaches, you have to know where they like to hide. If you know where the roaches are hiding, you can get rid of them before they get too close. 

Roaches can squeeze through cracks as small as 1/4 inch, so you should seal off any openings in the house. 

Run a bead of caulk around doors and windows and caulk in any cracks or holes you see. If the gaps are larger than 1/4 inch, you should use steel wool and caulk.

Ensure you store all food properly; to prevent roaches from infesting your home. They love dark, moist areas such as basements where they can find plenty of food and hide from predators.

Here are some other places that roaches like to hide:

  • Ceiling fans 
  • Behind wall outlets 
  • Places behind appliances 
  • Behind baseboards
  • Under furniture 
  • Under sinks
  • In the bathrooms
  • Pantry shelves

In general, the best preparation would be to keep them out with a solid foundation of sanitation and baking soda or borax and essential oils.

What Kills Cockroaches Instantly?

Borax is a white powder compound composed of boric acid, sodium tetraborate, and water. It kills roaches instantly. 

Traditionally, it has been used to control household pests such as cockroaches, ants, termites, and other crawling insects since long ago. 

You can find borax in the household cleaner aisle in most grocery stores.

Borax is an effective, natural, and safe way to get rid of all different kinds of insects. Borax powder mixed with sugar water makes great bait for roaches. The sugar water provides food, and the borax dehydrates them.

  • Mix 1 cup of sugar and one teaspoon of borax in 1 quart of water. 
  • Stir until the borax dissolves.
  • Next, put the mixture in a jar or bottle
  • Use it to dust near the places where you see roaches.

The two most popular pest control methods involve insecticides and traps. While both are effective, neither is perfect. It would be best if you used insecticides sparingly because some are toxic to humans, too. 

Pesticide spray only kills roaches on contact, so it takes a lot of time and effort to kill them all. Roach traps can be a pain to maintain because they require you to replenish the bait constantly.

The best pest control system has two main components: the baiting station and the attractant gel. 

The baiting station lures in cockroaches using an irresistible bait. The attractant gel contains a powerful insecticide that will kill the roaches once they eat it.

This combination of these two components makes the pest control system so effective. You can leave the baiting station out in your home, and cockroaches will come to it on their own accord. The attractant gel is completely odorless, which is a bonus!

The new and improved EcoSmart roach killer is the best of both worlds. It combines a powerful insecticide with essential oils such as rosemary and cinnamon. This means you don’t have to worry about your home smelling of harsh chemicals.

It kills roaches upon contact, making it highly effective. In addition, it’s environmental- friendly and non-toxic, being a 100% organic product.

What Smells Keep Roaches Away?

Roaches use their antennae to detect smells and prefer to stay away from strong scents. 


Diffusing lavender oil in your home is an excellent way to keep roaches away. Roaches hate the smell of lavender, so they’ll stay away if they detect it. Lavender oil is available at most health food stores and smells great!


Roaches are repelled by the smell of peppermint and will leave your house quickly if they smell it. 

It’s easy to make your peppermint spray with water and peppermint essential oil. Spray it on areas where roaches are known to gather, such as kitchen counters and under the sink.

Other scents that repel roaches include;

  • Citrus
  • Cypress Oil
  • Cedarwood
  • Citronella
  • Crushed bay leaves and coffee grounds
  • Eucalyptus
  • Tea Tree oil
  • Garlic
  • Cinnamon

Essential oils can be very effective at keeping roaches away, but they can also irritate if you get them in your eyes or breathe them in. 

Make sure you dilute the essential oil before spraying or diffusing it so that you don’t get any irritation.

You can make an essential oil spray for roaches in a few different ways.

  • You can mix the essential oils with water and spray them directly on your kitchen counters, or 
  • You can blend baking soda and water and add the essential oils. This will allow the baking soda to work as an antacid while also releasing the scent of the essential oils into your home.


As the name suggests, ultrasonic pest repellers emit high-frequency sounds that are inaudible to humans but highly irritating to pests like roaches and rodents. 

While some users have claimed success in using these products to eliminate their infestation problem, it’s important not to expect them to be the solution for your pest control problems.

If you have roaches in your home, you might be tempted to try and eliminate them on your own. However, if the infestation is severe, it’s best to call in professionals at a Pest Control Company. With their experience and tools, they can deal with any roach problem efficiently.
