I don't know how anyone could just live with it, but I'm sure I'd be surprised to know the truth of it.
I wondered if there were some folks that fleas would not be attractive too. You know "they" say that certain vitamin B types cause a person not to smell attractive to mosquitos. I wonder if there is anything fleas would find offensive that humans or pets could eat, that was natural like that. I don't know the answer to that.
There's a homeopathic remedy that supposedly makes the body unsuitable for fleas - Caladium. I used it, and it did seem to help. There's also a remedy for dogs - Psorinum. I haven't tried this yet, but I have the stuff. When I am certain I am 100% on top of this problem (there's still the yard to deal with), I will try it, along with essential oils on my dog. Problem is that the oils that repel fleas also antidote homeopathic remedies. We'll see!
