Thanks for the great recommendation Sur3fir3! I went with it after doing some more research. The neighborhood Feed & Seed store had a big bag available and I used a small children's nose mister do spread it around the floors in my house. I wore a respirator and while it created a 'chalky-like' cloud in the room, I never felt any irritation. I also ended up sprinkling it on my dog and rubbing it into his skin. After returning from dinner a couple hours later, I checked the dog and didn't see any more 'live' fleas. So far it looks like it's doing it's job! Kudos to your helpful tip!!
