Just found a interesting web site sounds like great products to get rid of Fleas in the house & Yard sounds very safe too.

I remember these guys! I used to have them come out once or twice a year back when I had my last kids, Fred and Jessie (and Chester and Simon kitties). The product seemed to work great and they told me then it was safer than common table salt, the guys baby would crawl around in the powder. Hallie has not had fleas since I got her, so I haven't had to use anything since or I'd probably still be using them.
