Ultrasonic Repellers These devices emit high-frequency sounds that are disturbing to bats but undetectable to humans. They are an effective bat repellent in areas like attics and basements.
Natural repellents like cinnamon, peppermint, and eucalyptus oils can deter bats due to their strong sense of smell. Apply these oils on potential entry points or use them as a spray around your property.
Unfortunately there is no such thing as a "bat repellent". There are many gimmick devices out there claiming to be repellents, but they flat out do not work. High frequency devices that plug into your wall will not work either.
Because they have a sensitive nose, they are afraid of strong odors. Cinnamon, eucalyptus, cloves, mint, and peppermint are all repulsive to them. Loud noises might also frighten them away.
One way to get rid of bats is to use a product called a one-way exit valve—a device that allows the bats to exit, but doesn't allow them to return. This type of device works by providing a small hole that bats can pass through, but won't come back out of.
Bats have a strong sense of smell and are commonly thought to be repelled by certain natural scents. For this purpose, some homeowners use peppermint oil, cinnamon, eucalyptus oil, cloves, and garlic as bat repellants.
Yes, bats return to the same place every night. They will also return to a known roost after being gone for months or years. They remember the location, especially if they are looking for a place during the maternity season, and they will return.
Bats have few natural predators — disease is one of the biggest threats. Owls, hawks and snakes eat bats, but that's nothing compared to the millions of bats dying from white-nose syndrome.
Instead, use tubes or netting as one-way valves that allow bats to leave, but not to reenter. These valves (or exclusion devices) must be placed over all openings that bats use to enter and exit. Valves may be constructed from well-cleaned caulk tubes or plastic pipes.
If you want to implement a practice to deter bats, putting up bright lights probably won't do the trick. It seems reasonable, as bats will avoid bright lights, but it often exacerbates the problem.
Broadcasting ultrasonic sounds at the frequency range which bats use for echolocation may act as a deterrent by interfering with their ability to perceive echoes.
While mothballs are often considered a do-it-yourself home remedy to bat problems due to their strong odor and chemical properties, they are generally ineffective against bats, and their use for this purpose is not recommended due to health and environmental concerns.
The deterrent system emits an ultrasonic acoustic field in the same range as bats' natural calling frequencies. This interferes with their ability to receive and interpret their own echolocation calls and creates a disorienting airspace that is difficult to navigate.
Ultrasonic devices are not effective in repelling bats.
However, these chemicals could seep into humans living quarters posing a significant health hazard to people. Use of these chemicals also greatly increased the risk of humans and pets coming into contact with sick or dying bats.
Fact: Bats are afraid of people and avoid them. Bat echolocation is highly sophisticated and enables them to detect obstacles as fine as human hair, therefore easily avoiding your head. If a bat gets close to a human, it's usually because they are curious about insects that are naturally attracted to people.
Use bright, motion-activated lights to deter nocturnal bats by creating an unwelcoming environment. Keep the porch clean and free from food sources such as standing water and insects to discourage bats. Employ scent and noise deterrents like peppermint and eucalyptus oils, and ultrasonic devices to repel bats.

Turn your ANDROID/iOS phone or tablet into a state-of-the-art bat detector. (Visit www.echometertouch.com/android for a full list of ANDROID devices and USB-C adapters that known to work or not work with Echo Meter Touch 2.) Listen to and record bat echolocations in real-time and see the echolocations on a spectrogram.
Whether you use netting, cones, or any other one-way exclusion material or device, the bats are going to see that something is awry, and balk at leaving. Sure, if you set it right, they will eventually leave, but I've seen problems. Sometimes they are stubborn. Sometimes your exclusion device didn't work as planned.
The most effective and humane way to remove bats is by using a bat valve in conjunction with a full home exclusion. A bat valve allows for bats to exit your home but not re-enter. Once the bat valve is installed, all other entry points will be sealed, allowing for bats to only exit through the valve.
Collisions with wind turbines and white-nose syndrome are now the leading causes of reported MMEs in bats.
When it comes to navigating at night, bats are among the champions of the animal kingdom. But it turns out that these fuzzy fliers do have one weakness: super-smooth vertical surfaces. Bats find their way in the dark using echolocation—sending out sound waves and listening for their echo.
March – Some begin coming out to find food as it gets warmer. April – Most have gone out of hibernation by now and are very active and very hungry, they'll be out foraging for food every night. June – Baby bats are born. Adult bats are consuming large amounts of insects.
Bats in the home can be dangerous because a few may carry rabies. It may be necessary for the bat to be tested for rabies if someone in the home was exposed to a bat bite, bat saliva, or bat guano.
Natural Repellents
Bats don't like some smells and lights. Here are some natural ways to keep them away: Bright lights in attics or where they enter. Ultrasonic devices that make high-frequency sounds.
