I Need Help ASAP 😰

So my daughter was doing tummy time next me on our couch and then she rolled over and I found this thing crawling from right under her. I figure out it was a tick I quickly removed her and stripped the couch and found another. Mind you I have two dogs. I have yet to check which has it but I don’t know what to do to clean the couch carpet bedding etc the dogs are on everything and our whole upstairs is carpet and baby is on it and they also sleep with us. First time they have had it so I don’t know what to do. I did go and give them their medicine but what else can I do to sanitize everything before my baby is back on the floor or couch or bed. Also dogs go in her room.
