How to Get Rid of Fleas Without Chemicals

The easiest way to get rid of fleas without using chemicals is to keep the fleas out of your home by washing bedding and vacuuming at least once a week. Using a vacuum cleaner is especially beneficial, since fleas live up to 100 days without a blood meal and lay eggs within 36 to 48 hours.

Diatomaceous earth is a natural insecticide made of skeletons of tiny organisms, and it works to kill fleas by drying them out. Be sure to use it safely, though, as it can cause respiratory issues if inhaled. Another natural way to kill fleas is by growing plants that repel fleas. One plant that repels fleas is pyrethrum, also known as painted daises or Chrysanthemum cinerariaefolium.

Another effective way to get rid of fleas is to make a homemade flea spray. A mixture of four parts vinegar and two parts water can be used to kill fleas and their eggs. Make sure to wash your bedding, window sills, and floors thoroughly before you apply the homemade flea spray.

You can also use essential oils to kill fleas. However, essential oils should be diluted in a carrier oil, like grape seed oil. Various essential oils can be found in the home, and some are water-soluble.
