Fleas

Hey everyone my dad found a cat and it has fleas badly. We currently have it on the porch I bought it in my room for a couple of hours when we first got it. But I didn’t realize it had fleas. And now my room has fleas I have flea bites on my ankles. I have tried benedryl and benedryl cream witch hazel and calamine lotion. I have vacuumed my room and they seemed to calm down a little what else can I do ?
