Preventing a Flea Infestation from a New Cat

Ditch the frontline. It is poison after all. Get dry 20 mule team borax into all carpets, rugs, furniture. Carpets, 2 cups (or more) dry sifted for average size room. Leave down 2 weeks before you vacuum. It takes 2 weeks for life cycle of egg larvae and adult. No fleas will survive in the house for over a year and a half if you don't reintroduce from the outside. Outdoor yard, fleas will freeze over winter. In spring and summer if no fleas are introduced you should be flea free. I never had to try it but I am told Sevin dust powdered into lawn areas kills fleas but has to be replaced periodically.
