Bobo's flea problem

it has been 5 days since we start 'bombing' the whole house using flea smoke. we use
Zodiac Household Flea Spray 400ml to treat the whole house! The easy to apply aerosol contains no CFC’s. It treats up to 35 meters square and unlike other aerosols, is designed to be used upside down to direct the mist to those hard to reach places; floors, furniture and bedding. The pyrethrins will kill emerging adult fleas while the Precor. Will provide 7 months protection from developing eggs and larvae.
recall the very day i found large fleas on bobo, it was hair raising! i just can't believe i've killed 26 fleas! that haven't put into account my boyfriend found on his bed...20 fleas!
that very morning, we sent him for a wash and flea treatment and have his fur cut shorter. that day, Rain ( the girl that own the pet shop ) told me that i have to apply a med two days later to kill any flea and its eggs left on him after the treatment. for a few days, Bobo was very upset and feel blue. he have no mood to play or eat...it was sad days...
today, he finally have a little bit of mood to play. and the have his appetite back. today he finish 3 times of meal!
