Battling fleas!

[MiamiE]

Seems as though I have a new found flea infestation in my backyard. I use K9 Advantage on both my dogs but still have to remove the occasional flea after they are outside. Today my 12 week old puppy had tapeworm segments in her stool. After some research it seems this is contracted after eating a flea carrying the eggs. I just got done giving her last dose of parasitic and this comes up. Going to the vet in the AM to see what he says. I am worried my other dog can get the worms, as well as my wife and I! Anyone have any personal experience dealing with fleas, and worms? I am also looking to buy a good insecticide for the yard and for my carpet inside the house. Any recommendations? Thanks guys!
