Stick to an all-natural flea-killing recipe such as one made from Borax and salt.

Things You Will Need

  • Vacuum cleaner
  • Garbage bags
  • Bucket
  • 1/2 lb. refined salt
  • 1/2 lb. Borax
  1. Vacuum every room infested with fleas. Place the vacuum cleaner bag in a sealed garbage bag and set in an outdoor trash can.

  2. Combine 1/2 lb. of refined salt and 1/2 lb. of Borax in a bucket. For larger areas, simply use equal parts of salt and Borax.

  3. Sprinkle a light coating of the Borax/salt mixture over the floor. The fleas will crawl over the mixture, which will pierce their exoskeletons and cause death from dehydration.

  4. Wait 12 hours and vacuum up the dead fleas along with the Borax/salt mixture. Immediately remove the vacuum cleaner bag and put it in a sealed garbage bag. Set the bag in an outdoor trash can.

  5. Repeat application two weeks later to kill any new fleas hatching from eggs that were not harmed by the Borax/salt mixture.

The Drip Cap

  • Fleas are known for plaguing dogs and cats, causing serious itching and skin irritation.
  • The fleas will crawl over the mixture, which will pierce their exoskeletons and cause death from dehydration.
  • Wait 12 hours and vacuum up the dead fleas along with the Borax/salt mixture.
