Control of Lizards/Anoles and Such
What can I do as a preventive measure to keep these reptiles from undermining my paver patio in the back yard. Most of these things are irridescent green/blue hues to brown. Not sure what these reptiles are. They seem to eat bugs. Thanks for the info and help.
The critter that you are describing is most likely a Southeastern Five Lined Skink. You can see a photo of it on my webpage: http://okeechobee.ifas.ufl.edu/News%20columns/Leapin%27%20Lizards.htm. A more comprehensive page can be found at the Florida Museum of Natural History website: http://www.flmnh.ufl.edu/herpetology/florida-amphibians-reptiles/lizards
Skinks prey on insects, spiders and other small crustaceans. While they may burrow under pavers in sandy soils, it is doubtful they would be moving sufficient sand to undermine your stepping stones.
Some species of skinks are endangered or threatened, so be sure that the critters you see are not in that category before trying to eliminate them.
If you really feel that you must discourage them, general practices that reduce the number of insects may reduce their feed supply and encourage them to move to other locations.
