Vacuume everything, then, the only thing that worked for my sister and I who have both dealt with the issue numerous times because we foster shelter cats- using a fresh soloution of 1 part bleach to 20 parts COOL water, NEVER use hot, lukewarm is ok. Bleach everything you possibly can. Wash blankets, throws, rugs, ( we threw away small couch pillows)

Kkeep in mind that ringworm spores live for up to 2 years, but usually only affect people or adult pets if the immune system is already comprimised. This means small children,kittens & puppies, and older people and animals. Dermisol is the very best shampoo I can reccomend for getting rid of it on an animal in addition to fulviside which one has to get from a vet, and is given in food orally once a day. GOOD LUCK
