Response of (house) lizards to the sounds of various frequencies

In summary, the conversation discusses the issue of house lizards and various methods to get rid of them. The speaker mentions their own experience with lizards in their bathroom and the failure of repellents and ultrasonic machines. They question if there is any research on how lizards respond to different frequencies of sound. Other suggestions for dealing with lizards are provided, such as using a predator or traps, and some resources are shared.

Summary:: Is there any peer-reviewed research that tells how (house) lizards respond to sound of different frequencies?

At the very beginning, I must admit that my knowledge in Biology does not run beyond high school books.

We are becoming more and more disgusted with these house lizards. They "stole" one of the two bathrooms in our house! And they are littering everywhere. There are three "playful" lizards in the "stollen" bathroom, and we have tried so many times but they just won't get out of the house. Needless to say, none of us have enough courage to catch them with our bare hands.

I was searching online and Amazon came up with lots of lizard repellents. I know from experience that they don't work. Amazon also has many machines that say that they emit ultrasonic vibrations to force lizards out of the house. The accompanying reviews clearly show that they are all frauds.

Coming back to the question, is it really possible to ward off lizards using sound? Has any research been done on how house lizards react to different frequency sounds?

Most lizards are nothing to be worried about touching.
Even alligators are not that that difficult to handle safely (had a friend with a 4 foot (1.2192 m) gator).

How big are they?
If they are hand sized or smaller, use a butterfly net, if hard to catch.
Alternatively throw a sheet over them.
If you don't want to deal with them personally, try a predator like a cat (if not too big), a dog, or maybe snake (non-poisonous kind).
Lizards are cold blooded, so they will be slower and easier to catch when the temperature is lower.

You might also use or make traps, like sticky traps for insects (which can be DIY'ed by crumpling up packing tape with the sticky layer on the outside).

never heard of sound that repel lizards.

Don't try to use sound. Too many other problems.

Do you like cats? Maybe it's time to get yourself a home pet that can help to manage any pests in your house. Cats are very obedient too (oh wait, maybe not)...

Not everyone has the guts to touch a lizard ?:)

Cats are not an option unfortunately.

My strategy should be to first block all the hiding places for the lizards and then try to catch them in a butterfly net or something similar.

Here's another resource:

They suggest coffee or naphalene balls among other things.
Good point. Naphthalene balls should work.

I thought so.

1. How do house lizards respond to different frequencies?

House lizards have been observed to respond differently to different frequencies. They may freeze, flee, or approach the source of the sound depending on the frequency.

2. Can house lizards hear all frequencies?

No, house lizards have limited hearing capabilities and can only hear frequencies between 100-7000 Hz. They are particularly sensitive to higher frequencies between 2000-4000 Hz.

3. What frequencies do house lizards prefer?

House lizards have been found to prefer frequencies between 2000-4000 Hz, which is in line with their natural predator avoidance behavior. They are more likely to flee from lower frequencies and approach higher frequencies.

4. How do house lizards react to sudden changes in frequency?

House lizards have been observed to have a heightened startle response to sudden changes in frequency. This may be due to their sensitive hearing and natural reaction to potential predators.

5. Do house lizards habituate to certain frequencies over time?

Yes, house lizards have been found to habituate to certain frequencies over time. This means that they become less sensitive to the sound and may not respond as strongly or at all after repeated exposure to the same frequency.
