The smell actually gives me a headache. There were fresh droppings right next to it for a week even after constantly sweeping and mopping the floors. Bombs per room /might/ be okay for your pristinely-tiled porsche showroom garage.

For you, i have some feeble recommendations (they're at the end). Be careful.
