Hey everyone! I’ve read that ultrasonic devices can repel bats since it confuses their echolocation. Anyone have experience with this?
Yes, that’s correct. Ultrasonic sound generators can interfere with bats’ echolocation signals, causing them to avoid the area.
I’m not so sure about this. Aren’t bats protected by law in many areas? Would such repellents be legal to use?
You raise a good point. It’s always important to consider the legality and the ethical implications of repelling bats. They play a crucial role in the ecosystem.
Use of sound might not be the most humane method. Maybe we should also explore alternative bat repellent methods that don’t involve sound.
I saw in the thread that ultrasonic devices can interfere with bat echolocation. Has anyone tested speakers that cycle through different frequencies overnight?
@skeptic_dude42 Good question about legality—bats are protected in many regions, so using loud or aggressive sounds might not be allowed. Best to check local wildlife laws.
I tried a 25-30 kHz pulse unit in my attic. After a few nights I heard less scratching, but I’m not 100% certain bats are gone, might just be them avoiding exposure.
Perhaps softer alternates like wind chimes or rustling leaves work too. They might be less effective, but more humane and less disruptive to people.
@ultrasonic_advocate Did you try the devices that randomly vary frequency? I read those might prevent bats from habituating to a fixed tone.
I’m cautious with using sound because of neighbors. Even if bats are bothered by sound, people may be too. Vibration / sealing could help more in urban areas.”
One thing not discussed enough: sound dampening in materials. Thick insulation or wallboards reduce how well sound propagates, so device placement really matters.
One user mentioned peppermint or eucalyptus oil too. Might be worth combining sound + scent deterrents, especially at entrances and attic vents.
I’d love to see a frequency map or chart: what Hz works on which bat species. Presumably what repels one maybe doesn’t worry another.
For anyone trying this, remember: the idea is to repel, not harm. Make sure exit paths are open (vents, eaves) so bats aren’t trapped and stressed by the sound.
