Salt should not be used at all on the carpet or furniture.
Think about it. Your pets (and children if you have any, especially little ones) will be walking, laying, playing and everything else on those carpets. No matter how well you vacuum there will still be salt in the fibers, which will get into their paws and fur (and onto children's hands and feet). Then the pets and children will be using those same paws, hands and feet to rub their eyes with from the irritation the salt has caused their eyes. It can be extremely painful and extremely dangerous to your pets and to your children.
The same thing goes for Borax. Either one can possibly cause blindness.
I would not use salt. I use 20 mule team borax. It's in the sop aisle of most stores. My friend told me about it 2 years ago. She has not had any fleas and neither have I. We tell ever body, even the vet. Try it (it works).
No. Just sprinkle it liberally all over where you see fleas. You can sprinkle under cushions, under the bed sheets, etc. It is a great way to kill fleas. They hate salt.
Also vacuum all the time after it has sat for a few days. Make sure you either put a flea collar in the vacuum bag or that you empty the vacuum each time you use it to some trash receptacle outside.
Here is a great resource for home remedies and also the dish soap in one half inch of water works great too if you can set it up where the animals wont drink it and the light doesn't fall into the water!
I just sprinkle it all over the carpet and leave for a few days. If there are babies or animals with feet issues, then I would lay down a blanket over the salt. Also sprinkle it liberally under cushions and under the sheets on the bed and anywhere else you see fleas.
Once it has sat for a day or two, then vacuum all the time, it a a wonderful way to get rid of fleas. Put a flea collar in your vacuum bag if you have a vacuum bag or else empty it the minute you do the vacuuming, to some trash receptacle outside.
