I discovered lice on my daughter last week (live bugs & eggs. I've tried Nix and a prescription from the doctor. Within a couple days, I also found a couple live ones and some eggs on my mom (she is my daughter's caregiver over the summer). Yesterday, I found a live one on my ear. My mother and I did a couple home remedies but I am still finding eggs on all of us. How do I know if they are dead ----- how do I know if they are GONE?? I've done nothing but laundry & vacuuming & spraying throughout the entire house.
