To keep fleas from biting you take a spray bottle and some lemon juice from a lemon and and some water to make a lemon spray to spray on your body.
The fleas hate the scent of lemon and will leave you alone.
Consider even spraying some lemon juice on your couch, bed or anywhere else you're sitting or laying down.
Also if you have carpet sprinkle salt into the carpet as salt works as a natural home remedy for getting rid of fleas in your carpet.
Leave the salt in the carpet for up to 2 days to dehydrate and kill the fleas and then vacuum and steam clean the carpet.
Also steam clean your upholstery as well to get rid of the fleas.
