Frontline applications seem to have suddenly stopped working on our cats. Help, before I'm eaten alive by fleas!

We started using Frontline with great success about six months ago. We missed one application by about two weeks, fleas came back with a vengeance and now they won't go away. It's been over eight weeks since the missed application, so there have been two on-time applications since then. I find several large adults every time I inspect the cats and I see eggs on the cat's bedding. Bedding is being washed every three days, Roomba does the floors daily and I follow up with the nozzle attachment on a regular vacuum around the baseboards a couple times a week. We are seeing even more fleas despite these measures, probably because the weather is humid.
1) I see alot of hearsay on the internets about fleas developing a resistance to Frontline. Is it really possible, or is it user error? They say that Frontline kills adults before they can lay eggs, but I'm finding new eggs every day so that can't be true if we did it right and the stuff works.
2) Could we be tracking in new fleas from outside? There is grass outside our apartment that we rarely walk through. We're on the second floor and cats are indoor only.
3) Are the cats ruining the Frontline by trying to lick? They seem to get at some of it every time, but not all. We're applying between the shoulders as directed. Do we need to get head cones or something?
