Ok so first off I'm not sure where in the heck my son could even pick them up.But yesterday I found a single lice looking thing on his head. I lookd everywhere for nats or anymore of them and didn't see any. I also soaked his head with olive oil for a couple of hours last night hoping if there where any they would be killed. My question is how can I be sure it is lice? Could it be from my moms dog, could the dog lice get lost?I looked at all my animal babies and other than dandruff there was nothing I could see. I washed the bedding last night and was going to salt my carpet and vacuum just in case. But is there anything else I can do just in case?? He has only itched his head maybe three or four times since being awake. which is about two hours. I washed my head in using teatree oil last night. Any advice is needed and welcomed. My mom used RID on me as a child and that is all she knows. And there is no way I am going to do that.
