Getting rid of fleas is one thing, but keeping them away can be hard too. Try our homemade natural flea-repellent laundry soap to keep your pet's bedding flea-free.

Making your own laundry detergent is a great way to make your household greener, so why not extend this to your pets too? While choosing a natural flea treatment is the best option to keep fleas off your dog or cat, this can’t guarantee that you’ll be keeping the fleas out of their bedding. Luckily, with a few simple ingredients and a bit of DIY spirit, you can make a homemade natural flea-repellent laundry liquid that can help keep your pet’s bedding clean and flea-free.

The combination of these ingredients is not only powerful enough to deeply clean pet bedding but also effective at naturally repelling fleas. Lavender oil has a pleasant smell and calming properties that may help soothe your pet’s skin, while tea tree oil has natural insect-repelling properties that can keep fleas away.

Makes 2.5 quarts of natural flea repellent, keeps for up to one year


  • ½ cup liquid Castile soap
  • ½ washing soda
  • ½ baking soda
  • 10 cups warm, distilled water
  • 50 drops lavender essential oil
  • 25 drops tea tree essential oil   


  1. Mix liquid Castile soap, washing soda, and baking soda in warm water.
  2. Add lavender essential oil and tea tree essential oil to the mixture.
  3. Store in an airtight container. Optional: reuse an old laundry bottle for easy storage.

Make sure to mix the ingredients gently before each use and use ¼ cup per load of washing. Please note that while this recipe is a homemade natural flea repellent, this is not a treatment for fleas. It’s always best to speak with your vet for health advice and guidance on the best course of action for your furry friends.
