i had this problem and tried frontline plus, advantix ii and neither worked. i got revolution and this natural power stuff michelle had recommended. i tried to find the earlier link.....it is natural and dries the fleas up. you can apply it to them, their beds and such. revolution and this powder finally got rid of the varmits...along with daily vacuuming. i didnt have a huge amount of the varmits but just one is enough to disrupt the whole household. good luck i hope the pups dont have any reactions and yes usually Cedric will show a reaction immediately. hope it works and they vanish and never come back.
