These devices use ultrasonic waves to disorient and repel invading insects without the need for powerful chemicals. The best ultrasonic mosquito repellent can’t be heard by the human ear, so you can simply plug in or turn on the repellent then go about your day, knowing that the mosquitoes are being deterred by sound. These are our recommendations for the best ultrasonic mosquito repellents for your needs.  

How We Picked the Products

Methodology

Many years of experience with mosquitoes, chemical repellents, ultrasonic repellents, and mosquito killers, as well as extensive product research helped to form the basis for selecting the top products from 35 potential choices. I considered factors including the range of each product, the type of pests that it affected, the power source, and whether it was a standard ultrasonic repeller or a hybrid product. Additionally, any products with special features were typically given preference over similar products that lacked them. 

Given that each product only works within a specified range, any products with a very wide range or that came with multiple repellents were prioritized over low-range options. While the main goal was to find mosquito repellents, many ultrasonic repellents work on multiple pests, and these products were typically rated higher than those that were designed to repel a single type of pest. Some products ran on batteries, but these tended to be of lower quality than the wall-plug style of ultrasonic repellent. Overall, the products with the most outstanding features, quality, and product efficacy were selected.

Why It Made the Cut: This two-pack of ultrasonic pest repellents by Runadi is an effective solution for many different pests including mice, spiders, mosquitoes, roaches, ants, and other insects.

Specs:

  • Range: 2,500 square feet each
  • Pests: Mice, spiders, mosquitoes, roaches, ants
  • Type: Standard plug-and-play

Pros:

  • Broad range
  • Silent operation
  • Soothing blue light
  • Low power consumption

Cons:

  • Limited by physical objects (walls or doors)

The RUNADI Ultrasonic Pest Repellent is well suited to the task of repelling mosquitoes, roaches, mice, rats, spiders, ants, flies, fleas, and other insects. You can easily activate it by plugging it into an available power outlet, then holding down the button for three seconds. The repellent will then begin emitting a powerful ultrasonic noise designed to disorient insects and other pests within range, causing them to avoid the area.

Each device in this two-pack of repellents can be used to protect an area of up to 2,500 square feet, though it should be noted that any physical objects that block the sound waves will diminish the effect. For this reason, it’s advisable to use one repellent per room in a location that is unhindered by furniture or furnishings because walls, doors, and even thick curtains can impede the range of the ultrasonic sound. Users will recognize that the ultrasonic mosquito repellent is active thanks to the calm blue light it emits.  This product is intended to remain active 24/7 and has a very low power consumption, so it shouldn’t dramatically increase your monthly electric bill.

Some ultrasonic sound waves will be blocked, slowed, or redirected by solid objects, like a wall or furniture, but if the repellents are installed in multiple rooms then the ultrasonic sound can better permeate the entire home and drive pests away.

The ultrasonic mosquito repellent works by simply plugging it into an available power outlet. Keep in mind though that the manufacturer recommends placing it away from furniture and furnishings, like curtains. In addition to repelling spiders, mosquitoes, flies, roaches, ants, and other insects, the Gadino device will repel nesting rodents like mice and rats.

Things to Consider Before Buying an Ultrasonic Mosquito Repellent

Keeping mosquitoes and other pests at bay is an important task that should be entrusted to a reliable device, so before deciding on the best ultrasonic mosquito repellent to protect your home, take some time to consider the various types, ranges, and power sources in order to find the right product for indoor or outdoor use.

Type

Currently there are three main types of ultrasonic mosquito repellent, including standard, wristband, and hybrid.

  • Standard ultrasonic mosquito repellents are usually made to plug into a wall outlet or sit on a patio table. These repellents are the most frequently used because they can last for up to five years and the fixed range is ideal for protecting the home.
  • Wristband ultrasonic mosquito repellents are a relatively new innovation. Since they’re made to be worn on the user’s wrist, the ultrasonic range follows the user as they go on a hike, sit around the campsite, or head out on a nightly jog. However, the quality and repellent ability of these new products is still relatively unknown, with most examples failing to impress so far.
  • Hybrid ultrasonic mosquito repellents don’t rely on just one method for treating pest problems. The device emits an ultrasonic sound to drive mosquitoes and other pests away, but it also has a UV light to lure pests not driven away by the sound into a built-in bug zapper.

Range

The range of an ultrasonic mosquito repellent refers to the measured area within which the repellent is effective. Beyond the limits of this range the effect of the repellent is increasingly diminished the further away the pests fly or crawl. Typically the range of an ultrasonic mosquito repellent varies from just 1,000 square feet to over 2,000 square feet. 

It should be noted that any solid objects, like a wall, door, curtain, chair, table, or any other furniture or furnishings in or outside of the home will block, redirect, and impede the movement of the ultrasonic sound waves. Keep these limitations in mind when looking at the range of these products to better understand the true capabilities of the device. 

Power Source

There are only two main power sources for ultrasonic mosquito repellents: The traditional plug-and-play models and new battery-powered options that have yet to make a big impact in the industry.

  • Plug-and-play ultrasonic mosquito repellents are easy to use and can last for up to five years before needing to be replaced. Simply plug the device into a wall outlet or an extension cord to start repelling insects and other pests within the designated range. 
  • Battery-powered ultrasonic mosquito repellents can be moved around without any interruption to the ultrasonic sound waves that disorient and repel pests. However, the battery does need to be replaced or recharged regularly to continue emitting repellent ultrasonic sound waves. The quality of these new products is still improving, but currently plug-and-play models are more reliable and effective.

FAQs

Q: Do ultrasonic mosquito repellents really work?

An ultrasonic mosquito repellent is designed to emit an ultrasonic sound above 20 kHz, which can be used to mimic the sound of dragonflies, a natural predator of mosquitoes, in order to drive these pests away. The sound released by the repellent also has the effect of disorienting and confusing pests that are within range, which discourages nesting and repels the pests from the area. However, the ultrasonic sound is not a 100 percent effective solution, so it’s a good idea to pair an ultrasonic mosquito repellent with a simple bug zapper that can take care of any mosquitoes that are not repelled by the ultrasonic waves.

Q: Do ultrasonic pest repellers interfere with WiFi?

No, ultrasonic pest repellers don’t interfere with WiFi signals. The device simply emits a noise that is pitched so high that human ears can’t perceive the sound, similar to a dog whistle.

Q: How long do ultrasonic pest repellers last?

If appropriate care is taken to avoid dropping or otherwise breaking the ultrasonic pest repeller, then the device can last for between three and five years before needing to be replaced.

Final Thoughts

The silent operation of the RUNADI Ultrasonic Pest Repellent combined with its highly effective pest repellent function is a great choice for getting rid of mosquitoes. if you need more coverage than a single repellent can provide, the six-pack of GADINO Ultrasonic Pest Repellers is an excellent option.
