Are there any homemade remedies for fleas in the house?
Borax is great! It acts as a desiccant. The fleas eat it, then essentially die of thirst. (Crummy way to go, but karma aside, it’s a good solution.) Sprinkle borax liberally on your carpets/rugs. Vacuum up after about an hour. It’s probably best to do it a few times a week at first, but as time goes on you will only have to do it once or twice a month to catch newly hatched eggs and the live fleas your pets carry indoors. In case you’re not familiar with borax, it’s commonly sold as a laundry booster although it has myriad uses. You can find it at the grocery store or mega store near the laundry detergents or fabric softeners. It’s very reasonably priced, so you won’t go bankrupt using it frequently. For fleas on your pets, I also endorse the vinegar in the water an earlier user recommended. Brewers yeast tablets are also supposed to be helpful, but I admit I’ve never used them. Good luck!
