How to catch a lizard?

[Betty]

If he's okay living indoors I don't have much of a problem with him. If I go to pee and find him in the toilet taking a drink though I'm going to freak out and probably run screaming from the bathroom.

Snakes are rather icky and snakes with legs I think fall into that category.

Can they climb on walls or anything that's going to freak customers out? I wonder if they eat or repel mice? Not much of a bug issue but we're in a pretty rural area and have mice problems every now and then.
