I tried using Advantix 2 on Cai for the past two flea seasons with 0 luck. I didn't even bother with Frontline because I've heard from others in my area that it didn't work. After the topical failed, I had to bathe him twice a week and have flea comb sessions with him every day. I tried Trifexis and within a week, the fleas were gone.
As far as the inside of your house, I have three suggestions; vacuum, vacuum, vacuum! Even if you don't have carpeting. It was the only thing that got rid of my flea infestation before I even had a dog. Exterminator came twice a month all season long and saturated the floor with poison. They were still hanging on.
Try vacuuming everyday for at least a week (while continuing to wash bedding and so on) and that should put a stop to them. *(Empty the bag or the canister in the OUTSIDE garbage every time. Fleas can hop out of trash cans.)
