We live in a modern house which I Hoover daily but I have three cats . 2 are 14 and we have never had a flea problem , we also have a three year old long hair and no have a flea problem. She doesn't seem to have any on her ( I flea comb them daily ) but sleeps withy dd and she gets bitten . I have used the stuff the vets sold me but it isn't working . Any bright ideas . We are moving to a posh new house in August and I don't want bloody fleas in it and don't want to leave a flea infested house either !
