Deep vacuuming: is probably the most effective for upholstered furniture, but keep in mind that once an animal is in the house, the fungal spores can be everywhere and can survive months. Wipe surfaces clean and spray non-porous non-edible surfaces with a fungicidal disinfectant. Check everyone carefully for skin lesions and treat promptly. Not everyone exposed to the fungus will get ringworm lesions.
