While it can happen with q concrete floor, around here any other than concrete will get us into a long battle with things digging and making tunnels under any other we use for flooring in barns.
Mice and rats, skunks, coons, badgers, rabbits, you name it, they give it a try to make themselves at home.
Why that matters to us, then rattlers come to the buffet and that becomes a real hazard, why we have concrete floors most places that will have stuff piled on it, hay, shaving bags, trailers, wheelbarrows.
By the time you price material, mats and labor, concrete is not that much more.
