How to Kill Fleas With Household Supplies

Fleas can compromise your pet's health and cause him distress. They are small, blood-sucking parasites that make their homes on your household pets and even on you. What can start as a few fleas on your family dog can quickly turn into a full-blown infestation of all your animals, yourself, your furniture and your carpet. Fortunately, there are home remedies employing items you have around the house that will kill the fleas without harmful chemicals.

Step 1

Add brewer's yeast to your pet's food. Use one teaspoon for cats and small dogs and one tablespoon for a dog of 50 pounds or more. Stop using the yeast if your pet shows signs of an allergy to it.

Step 2

Grate a clove of garlic into your pet's food every three days. For cats, cook the garlic before adding it.

Step 3

Give your pet a B1 supplement. Check with your veterinarian for the specific dosage for your pet.

Step 4

Add one teaspoon a day of apple-cider vinegar to your pet's water bowl to increase her immune system.

Step 5

Bathe your pet daily since fleas cannot live in water. Do not use flea shampoos daily because this can cause excessive drying of the skin.

Step 6

Inspect your pet daily for fleas. Use a flea comb that has been coated with petroleum jelly to catch the fleas in the teeth of the comb. Dispose of fleas in a cup of water that you then flush down the toilet to drown them. Use a white towel under the pet when you are brushing him to catch any fleas that try to jump off.

Step 7

Set a bowl of water in the middle of the floor at night. Add a few drops of dish soap and mix slightly. Place a desk lamp over the pan to attract fleas. Dump the pan of water into the toilet and flush away the fleas in the morning.


  • Check with your vet before giving a food supplement to your pet.
