A combination of Nitenpyram and Lufenuron (generics of CapStar and Program, respectively) would be the cheapest, safest option. Little City Dogs is the brand I buy for Lufenuron on Amazon, as well as their own website (little city dogs .com) sometimes amazon is cheaper, even with shipping, than the website, even though it’s the same people company, so just price check the two. The “Flea Killer” is the CapStar and the “Flea Control” is the Program. Both are safe for momma dogs, and both can be given directly to puppies once they are 4 weeks old. Use Nitenpyram daily until most of the fleas are dead, and then continue Lufenuron, at the same time, monthly to prevent eggs from hatching. Any existing eggs will hatch, so keep the Nitenpyram handy for the second generation. Also keep the house and furniture vacuumed and flea comb all pets daily, rinsing the comb in warm, soapy water often. It doesn’t take long until you’ll see a difference.
