A lizard trap is a device used to capture lizards. Lizard traps come in a variety of shapes and sizes, but they all work on the same basic principle: they use bait to attract lizards, and then they trap the lizards once they enter the trap.
Lizard traps can be an effective way to control lizard populations in areas where they are considered to be a nuisance. They can also be used to catch lizards for research purposes.
