Can anyone advise me of a good worming and de-fleaing treatment please?

Personally, I strictly stick to the stuff from the vets - Drontal for worms, Frontline pump for adult fleas and Staykill spray for the house (for the flea eggs, larvae and pupae.) I never buy over the counter treatments like the Bob Martins and the like! The way I look at it is that if it doesn't require veterinary prescription it 'aint strong enough! :)
