BSH....I did look into this recently. I think that in other countries Stronghold do 2 different versions, much like Frontline here. So it may be that the one you listed ( I have not checked) is the flea only version NOT the all round flea and wormer.
Frontline has become less effective in flea prevention in recent years, well, certainly the version we can buy from Chemists etc. In my opinion, if you are going to use a treatment..buy the all rounder from the vet and do it properly otherwise risk a very itchy few weeks before you can apply a different product!
I am interested in the idea of the bombs as a house treatment as my house is due a spray with Indorex and I have a new kitten who has brought lodgers with him.....
