Dry 20 Mule Team Borax (2 to 2 and 1/2 cups per average carpeted room), I put it in a sifter or veggie drainer and spread over carpet, dog bed, couch etc. Leave for 2 weeks and vacuum. 2 weeks to complete life cycle of egg - larvae - and adult. Good reports although I have not tried is rock salt in the yard.
Natural way is bathing your dag in warm salt water. Steeping rosemary and adding it to the warm bath of salts will help keep fleas off the pet. I read this somewhere, when I had a dog it worked great. I never wanted to use the chemicals on her. Try this, worked for me.
If they are where your pet sleeps,put lavender oil on cotton balls or on bedding. Tea tree oil works ,too. Just dampen the area with these oils, flees cant stand the smell is what I thought. Either way it works!
