Do Lizards Make Sound? Lizards are known for many things, but their conversational abilities aren't among them. Very few of the nearly 5,000 species make vocal sounds, meaning it is a rarity to hear lizard noises. Geckos are the chattiest of the common species, communicating with a variety of chirps, squeaks, and clicking sounds. The chirping is used to define territory and also as a mating call. Other Lizard Sounds Hissing is a lizard noise that can be made by a wider selection of species. They use this sound to communicate discomfort and fear. The reptiles usually keep their teeth bared after making the noise in an attempt to intimidate. Other species can emit squealing sounds or low growls as defense mechanisms. Controlling Populations While it is difficult to use lizard noises as a gauge of nearby populations, small numbers of reptiles in yards aren't usually a problem. An overabundance can damage plants, weaken sidewalks and patios with their digging, and spread diseases. Homeowners with properties overrun by lizards can call Critter Control for safe and effective removal.
