We have rodent problems in our outbuilding over the winter. They are mostly deer mice. I always worry about hantavirus and wear a respirator while using a vacuum with a Hepa-filter. I prep by spraying the droppings down with bleach and sweeping up the ones that I can get to.
I’ve done the same - worn a respirator, used a vacuum with a HEPA filter and sprayed the area beforehand with 10% bleach solution in water. Wore nitrile gloves when moving boxes, tools, etc. and washed in soap and water before disposing, then soap and water for hands.
