A few anoles on the stucco is normal South Florida. A garage that's become a lizard highway is a different problem — droppings on the cars, shed skins in the corners, and a steady trail under the side door.
Why they're in the garage
The garage is warm, it's full of insects (especially around the door seal and the lights), and there are gaps under the doors they slip through. The garage isn't the attractant — the route to it is.
The threshold fix
Shake the powder along the exterior foundation line and across the threshold of the garage door and any side doors. The lizards avoid the banded threshold and stop using the garage as a through-route. Seal the obvious gaps under the doors while you're at it.
