What's a Good Household Flea Killer?

A variety of common household items can be effective in eliminating flea infestations, including table salt, citrus fruits, flea combs and Dawn dish soap. The best way to eradicate fleas is to combine multiple methods, as a single one is unlikely to completely work.

Table salt and borax sprinkled on household surfaces dehydrates flea eggs and prevents new generations from emerging. This is best combined with frequent vacuuming to remove all the flea eggs and larvae from the house. Citrus fruits and essential oils such as cedar and lavender can function as repellents and reduce the likelihood of fleas jumping onto pets. Washing pets with Dawn dish soap can kill fleas on contact and works best with a post-bath flea combing.
