Hi Harpers Mom,
From your previous posts I see you’ve been dealing with fleas for nearly a year now. To win the battle it is essential to break the life cycle and hands down the best way to do that is with lufenuron. Administer it once a month with a full meal; stay the course. The flea life cycle can be several months long from start to finish. The eggs that were laid prior to lufenuron use will progress through the life cycle so it may be 3 months before you see the results from lufenuron. All animals in the home need to be on some form of control. If you have species that lufenuron isn’t being used in you’ll need to ask your vet what should be used in those species.
Capstar works well as an adulticide. I consider it super safe but it needs to be repeated frequently. In heavy infestations every 2-3 days.
Mechanical removal through vacuuming, and environmental spot control as necesary will hasten the process. I wouldn’t ever use DE.
