Best Ultrasonic Bat Repeller

19 min read| Updated for November, 2019


Bats can find openings between the walls and roof of your home which create easy passageway into your home.
Prevention is always the best step when it comes to keeping out bats.

The Best Ultrasonic Bat Repeller

You may remember from your school years that bats navigate via echolocation. A bat uses echolocation by sending out high-pitched sounds that then come back to help them detect where objects are while they fly in the dark of night. It’s for this reason that ultrasonic devices can be especially useful in repelling bats compared to other animals and pests.

When you confuse their sense of navigation with the high-frequency sounds of an ultrasonic deterrent, you make the area of your home inhospitable for bats to fly around. Below you’ll find our favorite ultrasonic bat repellents on the market right now.

  • Deep penetration with 9,000 square feet of coverage
  • Plug in, simple to use

Our Review

When it comes to bats in the attic, no one wants them. That’s why we looked at the Cleanrth CIN009 Industrial Electronic Pest Repelling System. The unit is simple and easy to use, just plug it in and leave it. The Next Gen technology offers deeper penetration with electromagnetic waves that disrupt the communication and living of bats, upset their nervous system, and sends them packing.

The ultrasonic vibrations fall outside of the hearing ranges of humans and pets, so your day-to-day lifestyle won’t be interrupted. The unit is rated to cover up to 9,000 square feet of open coverage but will still go deeper in the walls of your home or office.

In addition to bats, the Cleanrth CIN0009 will also work to repel insects, squirrels, mice, and rats. Good for use in your home, garage, and outdoor area.

ET Pest Control


  • Two high powered speakers for greater repelling coverage
  • For indoor or covered outdoor use
  • Plug in, simple to use
  • Outstanding user ratings, excellent quality


  • Needs electric source
  • Can take up to a month or more for successful results
  • Not water resistant


We love the fact that the ET Pest Control comes with TWO high powered speakers for wider and deeper repelling coverage.

Our Review

If you have bats in and around your home and property, the ET Pest Control is the essential bat targeting system you need to employ. Setting the unit on High Range will send out high impact ultrasonic sounds, penetrating through walls and floors, covering roughly 5,000 square feet. This technology upsets and unsettles the winged critters, encouraging them to set up shelter elsewhere.

A plus the ET Pest Control has that other don’t is Twin Scanning Technology, which includes two high powered speakers for greater repelling coverage. And the high impact repelling works with the wiring within your walls for greater irritation to these pests. The solution is simple; just plug the ET Pest Control in and near your trouble spots, then give it time to work its magic.

An important reminder is to select the High Range to repel bats. The Low Range targets rodents such as mice, rats, and squirrels.

How to Deter Bats

Bats help the environment in a variety of ways, one of which benefits you directly—by eating up large amounts of insects. So, you don’t want to kill or hurt bats if you have them nearby. However, if you’ve ever had a bat inside your home, you likely felt some anxiety about getting it out and keeping anymore from getting in.

If you own pets and need to let them out at night, you might also worry about rabies if you reside in a highly-populated bat area.

While most bats do not have rabies, they indeed pose the risk of carrying the disease, and a bite from a bat can be vicious. So, doing what you can to keep bats flying away from your yard is a smart idea. The excellent news is that there are some methods to keep bats away safely while still being safe for them and other wildlife.

Methods to Use with Ultrasonic Bat Repellents

As we mentioned, safe ultrasonic bat repellents are among our favorite ways to get rid of bats because of their effectiveness with a bat’s echolocation. However, if you want to be sure these winged creatures avoid your yard and house, there are a few methods you can combine along with an ultrasonic device for maximum success.

Outdoor Lights

Switching your outside lights to yellow outdoor bulbs will attract fewer insects. A lightbulb with a swarm of insects nearby or heading toward it is like a buffet for a bat. So, keeping bugs at bay will give bats less reason to hang around. Using eco-friendly, pet-safe yard sprays for bugs is another way to minimize a bat’s food supply.

If you’re aware of a specific location that bats made a home near or on your house, you can also shine a bright light directly on that spot 24 hours a day until the bats leave. Using an LED light for this purpose will be kinder to your energy bill. Just consider any neighbors nearby if you try this method. Creating light pollution or accidentally shining a bright light in their window likely won’t go over well.


Ultrasonic devices are an earth-friendly, safe way to repel bats and can cost very little for the length of time they remain useful. You can always double up on more than one type of ultrasonic device, or combine one with another wildlife-safe method of deterring bats.

We like using a quality ultrasonic device that plugs in both outside on a porch, as well as using one with a light deterrent out in a yard for dense bat areas. You can then rest easy that the bats will fly off safely to eliminate bugs while keeping clear of your home.
