Can you please tell what the side effects of inhaling kerosene would be on a 79 year old man. He thinks it has disinfectant benefits and also thinks it kills allsorts of bugs and bacteria. He told my sister back in Grandma's day she used to spray it around. I have asked his sisters about this but they can''t remember it ever been sprayed around but his mother did put it in the kids hair to get rid of nits. He uses it everyday spraying his bedding and his washing. It is so potent that people have to walk out of the house because of the fumes. We have tried to tell him its not good for him but he is a very stubborn old bugger. Help please
