Try These Four Natural Solutions To Fight Fleas And Other Household Pests

Love your cat but hate the fleas that come with it? Constant bites causing itchiness and killing your mojo? Want to get rid of the problem but are excessively worried about the chemicals in most commercial solutions (you shouldn’t be by the way, they are perfectly safe). Well no worries, because we got you covered: check out these four natural solutions you can use to fight fleas (and other household pests). Check them out below.

#1 – Put Them in the Ground with Diatomaceous Earth

diatomaceous-earthDia-what? Those fleas are dying, that’s what! Diatomaceous earth is a soft, crumbly, porous sedimentary deposit formed from the fossil remains of diatoms (a type of algae). They are lethal to fleas and other insects such as cockroaches and ants (by absorbing lipids from their waxy exoskeletons and causing death by dehydration) and can easily be purchased at most hardware stores. You can use it outdoors as well but keep in mind that that would require a very large quantity in order to be effective.


Food-grade diatomaceous earth


  1. Sprinkle the diatomaceous earth all over your carpets and wherever you think those fleas may be hiding. Make sure you use thin layers so that fleas will walk over the earth and not around it or by jumping over it.
  2. Leave for 12 to 48 hours, depending on how bad your infestation is, and vacuum thoroughly after.

Important Considerations

Diatomaceous earth is used in pool filtration systems as well, so make you use the food-grade one, as although they are both non-toxic, the former is hazardous if inhaled. Also, moisture and humidity reduces its effectiveness so make sure any surfaces you apply it to are completely dry.

#2 – Keep Them Away with Pennyroyal Herbs

pennyroyal-herbsPart of the mint family, pennyroyal herbs have been used for centuries to deter pests such as fleas, as well as ants and cockroaches. While it is a mint, please note that it is highly toxic to both humans and animals, causing cardiovascular collapse and liver toxicity. While it is also available in essential oil form, this is even more toxic and should be handled with even more care.

Ways to Use Pennyroyal

  1. Grow pennyroyal in your yard as an outer line of defense against fleas.
  2. Place some dried pennyroyal leaves in teabags and place them in strategic infestation locations. Make sure these teabags are not accessible by your children or pets.
  3. Wipe a small amount of pennyroyal essential oil on your pet’s collar, making sure it does not come into contact with its skin. Remove immediately if skin shows signs of irritation or allergy.

Important Considerations

As mentioned above but worth mentioning again, pennyroyal is highly toxic so take all precautions necessary.

#4 – Fleas HATE This Essential Oil Mix!

essential-oil-against-fleasWhile essential oils might attract hippies and annoying new-agers, the right mix of essential oils is an effective natural way of killing and repelling fleas and other insects. This new method on how to get rid of fleas will be easy for those who also have pets in their house since they are most likely the source of a flea invasion. It will also leave your home smelling nice; however there is a chance that it may attract hippies instead, which can be just as annoying as fleas.

Geranium essential oil (5 drops)

Lemongrass oil (10 drops)

Citronella oil (20 drops)

Water (1 gallon)


  1. Mix all the ingredients together in a bucket.
  2. Commence mopping; mop daily with this mixture for a few days, then when the infestation shows signs of abating, you can reduce it to once a week.
