Pet owners will inevitably face the problem of a flea infestation in their home from their beloved pets. Instead of reaching for chemical sprays or calling a pricey exterminator, try this household item instead: salt. Salt is a dehydrator and will dry out the bodies of fleas, effectively killing them without the use of chemicals. To de-flea your carpets, sprinkle a finely ground salt all over them. Use a light coating, but be even so it covers the whole carpet. Let the salt sit there for 24 to 48 hours (the longer, the better), and then use a vacuum to clean it all up. The fleas should be sucked up with the salt.
