All other members of the household, as well as caregivers, will probably also need to be treated, even if they show no symptoms. It's best if everyone gets treated at the same time, so one contaminated person doesn't reinfect everybody else.
Though there's little evidence that scabies can spread through linens and bed sheets, for peace of mind you'll want to vacuum the floors (throwing the vacuum bag in the trash), and then wash all clothing, towels, and bedding in water hotter than 140 degrees Fahrenheit and dry it in a dryer. (Remember to turn your water thermostat back down when you're finished, to avoid accidental scaldings.)
Seal any stuffed animals or toys that can't be washed in a plastic bag for a week. Unlike hardy head lice, which can live for up to two weeks in clothing, scabies mites can't make it for more than several days without a human host.
