How to Kill Fleas on a 6 Week Old Kitten

| Updated September 26, 2017

Things You'll Need

  • Dish soap

  • Water

  • Towel

  • Flea comb

It is common for adult cats to pass fleas on to their babies. However, veterinarians advise that kittens under the age of eight weeks not be treated with flea medication. The fleas can cause anemia in kittens, and they will cause the small kittens to scratch constantly, which can be very annoying and uncomfortable. You can use some safe home methods to get rid of the fleas so that the kittens can relax.

Fill your bathtub with about an inch of warm water. Make sure the water is lukewarm, not too hot.

Add a few drops of dish detergent and lather up your kitten. Let the kitten stay soapy for a total of five minutes. This should be sufficient time to kill all of the fleas.

Rinse your kitten off and then dry her with a towel.

Run a flea comb through your kitten's fur to collect any dead fleas.


  • Wash all of the kitten's bedding in hot water so that the fleas in the bedding do not reinfect him.

    Treat the mother cat with flea medications so she does not reinfect the kitten.

    Vacuum the flooring and furniture near the kittens and discard of the bag in an outdoor trash can. This should get rid of fleas in the area.


  • If you don't get rid of the fleas on the kitten, it could get anemia. The condition can be fatal in kittens.
