Fleas in the house. How do we get rid of them?

We have a bit of a flea infestation at our house and my husband and little girl are being bitten. We have had the council in 2 weeks ago to spary and haven't been allowed to hoover since then to allow the poison to remain in the house. The cat is Frontlined. Tonight i caught a flea as it jumped from my daughter onto the floor YUK!!! Any other things i can be doing or do we just have to wait......or should we get the council back in?
