In my experience, rattlesnakes show up exactly once, and then they realize I live here and I'm 1000x their size, and they never show up again. Lizards that live in my immediate vicinity eventually realize I'm not gonna eat them, and they continue hanging around (but I don't mind because I know they're harmless, they're like pets that I don't have to feed). I haven't seen many scorpions here, but I've read that all scorpion species which live in the continental US are pretty harmless (might be a painful sting but that's all).
I recently learned about an old-school strategy to prevent rodents from getting into a barn, where the whole structure was set on mushroom-shaped foundation blocks. The rodents can't climb up the overhang of the mushroom cap, so they'll never make it in. I don't know if that strategy will work for lizards if they have gecko-type sticky feet, but I would guess it'd be very effective against snakes and scorpions.
