Regular brushing and grooming can help you get rid of both live and dead fleas from your cat. Focus on regions like the neck, armpits, groin, and base of your cat’s tail, where fleas like to hide.



Fleas can also be eliminated by bathing your cat in a flea shampoo designed for pets. To avoid reducing the product’s effectiveness with increased bathing, follow the instructions for topical flea prevention. Flea shampoos should only be used sparingly because they can dry out your pet’s skin.

Pine Chips

Pine Chips

The smell of wood chips is well known to repel fleas, and there is a possibility that your cat will feel the same way. But you may try scattering cedar chips over your cat’s guest bedroom in your backyard garden. Since cedar oil is a safe, quasi-scented oil, you can use it to ward off insects by misting your cat’s fur or even its collars.



As citric acid is one of the most efficient natural flea killers, lemon juice is a well-known home remedy for treating fleas. Applying a mixture you made by cooking one or two sliced lemons and then filtering the liquid to your cat’s coat is possible.

Work the solution carefully into the kitten’s fur while being mindful to avoid getting it in their eyes and keeping an eye out for any burning or other discomfort signs. Once the fleas are gone, repeat the process as often as needed.


One of the simplest things you can do for cat fleas is to add natural ingredients. You can find them in your home for their food. Due to the presence of carvacrol, which is effective against fleas, oregano oil can be very effective.

Start by combining one tablespoon of essential oils with three teaspoons of olive oil, and then use a small amount of the mixture on your cat’s ear, belly, tail, and throat. Try powdering rosemary leaves and scattering them in areas of your home where your cat regularly coalesces because rosemary repels fleas.

Apple Cider Vinegar

Spray water on your cat’s fur with a sprayer. Before bathing, gently rub soapy water into the fur, paying close attention to the areas where fleas like to lurk.



Lavender is a robust and fast-acting flea repellant that also has a calming effect on your pet’s skin. It might even make you fall asleep. According to some studies, diluted violet solutions were equally effective at killing fleas as professional chemical sprays. Fresh lavender should be soaked in milk for a day before being filtered and sprinkled onto your cat’s coat to use correctly in your home.



You can also use loose chamomile tea, another ingredient with a good track record for skin healing, to eliminate fleas on your cat. Apply the mixture to your cat’s coat after the tea has cooled. Both treatments can be repeated daily for as long as necessary.


Cats can become ill from flea saliva owing to skin irritation, scabbing, and hair loss. Just one or two flea bites might set off symptoms, making even minor infestations problematic. The consumption of cat blood by mature fleas can cause hypoglycemia, lethargy, and even death in young kittens.

Fleas are necessary for cats to transmit the “cat scratching illness” to humans. The bacteria Brucella hensellae infects the host when parasites eat plasma. Nonstop scratching, areas with hair loss, and other behaviors are typical indicators of a cat with fleas.
