Anyone else heard of using vinegar to keep fleas at bay?

[nappyaddict]

Somebody has told me that a natural way of keeping fleas at bay is to add 2 tablespoons of vinegar to their drinking water and the same to their food (if they have wet food)

I've never heard of that and it sounds like a terrible idea! Would you like vinegar in your water and food? And I think the chances of it actually working are just about zero. It sounds like an old wives tale. I'd stick to Advantage or Stronghold if I were you.
