As many open areas between US and Mexico at least there are some natural barriers, but it is totally impossible to stop them once in CA or AZ. Red states would have to checkpoint everywhere.
Illegals don't just wander around though. They get transported by the Feds or NGOs, and I'm not just talking about Abbott and other Republicans busing them to blue areas to play politics. States could possibly arrest people for moving them around. It won't fully stop things because then illegals could wander in on their, but it would stop the industrialized operation.
