Q: I have at least four chuckwallas living in my backyard. I have identified them using photos on the Internet. They range in size from 6 to 14 inches. They are eating the leaves of my vegetable garden. How do I make them leave my yard?
A:ย The chuckwalla (Sauromalus obesus) is a resident lizard in these parts so your yard is also its yard. You canโt stop them; you can only hope to contain them. Your best bet in the case of any four-legged varmints eating your vegetable garden is to exclude them using a barrier so they cannot access your vegetables. Since these are relatively large lizards, hardware cloth and PVC pipe, or a reasonable facsimile thereof, can be used to fashion an enclosure they cannot penetrate that you can lift off when tending your garden.
