Divegirl, maybe Johnson's for fleas works for you, but I can promise you that it is a very poor product and I would not even entertain its use, if it worked do you really think that people all over the UK would be spending a fortune on flea treatments from the vet. The only way to treat fleas effectively is to get a product from your vet, this is usually Frontline. The only way to treat a house for fleas is to call in a professional pest controller and i'm not saying that just because that is my profession, even us pest controllers have problems treating fleas, hardly any profit and that soon disappears if we have to re-treat a property which unfortunately is a common occurrence.
