Have you ever been told that vinegar kills fleas? Well, fleas do hate vinegar. So much so that it makes a handy homemade flea spray. A pet who has been soaked or doused in a vinegar mixture will not be nearly as tasty to fleas. Here is how to make it: Simply find a clean spray bottle (one that has not been used with cleaning agents or anything similar) and fill it with ½ water and ½ apple cider vinegar. We like the apple cider vinegar because cats and dogs tend to lick themselves after an application, and the taste is a bit less offensive to them. But white vinegar will work just as well.
Homemade Flea Spray With Lemon:
Lemon is another natural, handy natural flea remedy. It's really easy to make a lemon flea spray. Take a couple of lemons, one to three depending on how strong you want it to be, and slice them very thin, keeping the peel on. Place the slices in a pint of water and bring it to a boil. Then let it steep overnight. Place the lemon infused water in a spray bottle and spray away!
