Flukes live inside the body and cannot survive outside. If you pass flukes in feces that is a clue. Theese are something different. I suggest you remove your carperüt completely, steam clean and place a wooden floor instead. Carpets are notorious for being a breeding place for all sorts of things, especially near kitchens or bathrooms. A wooden floor is a healthy alternative and easier to keep clean. In the kitchen/bathroom floor tiles are good too.
