The Science Behind Coconut Oil and Fleas

What is coconut oil and where can I find it?

Coconut oil is a highly saturated fat extracted from the meat of mature coconuts. It has gained popularity in recent years due to its numerous health benefits, versatility in cooking and baking, and skincare applications. Coconut oil can be found in most grocery stores, health food stores, and online retailers.

How does coconut oil kill fleas?

Coconut oil kills fleas by suffocating them. When applied to a flea-infested area, coconut oil forms a thick, slippery coating that makes it difficult for fleas to maneuver and breathe. As a result, the fleas eventually suffocate and die, making it an effective way to kill these small pests.

What compound in coconut oil is lethal to fleas?

The primary compound in coconut oil that makes it lethal to fleas is lauric acid. Lauric acid constitutes approximately 50% of the fatty acids found in coconut oil. When ingested or absorbed through contact, lauric acid has been shown to possess insecticidal properties, making it a successful treatment for fleas and other pests.

Is coconut oil good for controlling fleas?

Yes, coconut oil is an effective natural solution for controlling fleas due to its insecticidal properties and suffocating effects. It is also safe to use on pets and humans, as it poses minimal risk compared to chemical treatments. However, as with any remedy, its effectiveness largely depends on the severity of the infestation and proper application.

Does coconut oil repel fleas on humans?


Coconut oil can help repel fleas on humans due to the lauric acid present in the oil. Since fleas are sensitive to lauric acid and other components in coconut oil, they tend to avoid coming into contact with it. Applying coconut oil to the skin acts as a natural barrier, helping to deter fleas and avoid infestations.

Additionally, the lauric acid found in coconut oil has insecticidal properties that further assist in killing fleas and keeping your dog’s skin healthy.

Does coconut oil kill fleas on cats?

Yes, coconut oil can be used to kill fleas on cats. It works in the same manner as it does for dogs by suffocating fleas and utilizing the insecticidal properties found in lauric acid. However, it is essential to carefully apply coconut oil on cats as they are more sensitive to oils and are prone to lick it off their fur.

How long does it take coconut oil to kill fleas on pets?

The time it takes for coconut oil to kill fleas on pets can vary depending on the severity of the infestation and the proper application of the oil. In general, it may take between a few hours to a few days for the oil to completely suffocate and kill off the fleas. It is important to continue treatment for at least a week to ensure that all fleas, including those that were in their egg or larval stages, are eliminated.

Can coconut oil be used on kittens and puppies for flea control?

Coconut oil can be used on most pets, including kittens and puppies, as a flea control measure. However, it is crucial to use the oil with caution on pets younger than eight weeks of age to avoid potential health risks. Always consult a veterinarian before using coconut oil or any other home remedy on kittens and puppies.

What type of coconut oil is most effective at killing fleas?

Unrefined, cold-pressed, virgin coconut oil is the most effective type of coconut oil for killing fleas. This form of coconut oil retains the highest levels of lauric acid and other beneficial nutrients, making it highly potent against fleas and other pests.

Coconut Oil as a Flea Repellent

Does coconut oil repel fleas?


Yes, coconut oil can act as a flea repellent. The lauric acid present in the oil, which has insecticidal properties, deters fleas from coming into contact with surfaces coated in coconut oil. When applied to your pet’s skin and fur, coconut oil creates a natural barrier that effectively keeps fleas away.

Coconut oil can help repel fleas on humans as well. By applying the oil directly to your skin or incorporating it into homemade repellent blends with essential oils, you can create an inhospitable environment for fleas, reducing the likelihood of infestations.

How does coconut oil act as a flea repellent?

Coconut oil acts as a flea repellent due to the presence of lauric acid, which fleas are sensitive to and avoid. It creates a slick, oily barrier on the surfaces it’s applied to, preventing fleas from effectively moving and attaching themselves to the host. Additionally, the insecticidal properties of lauric acid help kill fleas that may come into contact with the oil.

While the lauric acid in coconut oil possesses insecticidal properties, eucalyptus and lavender oils have various chemical compounds that are toxic to fleas. Additionally, the strong scents of eucalyptus and lavender oils make them effective as repellents. However, eucalyptus oil may not be suitable for cats, and it’s essential to consult a veterinarian before using any essential oils on your pets.

How does coconut oil for fleas compare to apple cider vinegar, dawn dish soap, and diatomaceous earth?

Each of these remedies has its unique properties that make them effective against fleas. Apple cider vinegar, while not killing the fleas, can help repel them due to its strong smell and acidity. Dawn dish soap works by breaking down the fleas’ exoskeletons, effectively killing them. Diatomaceous earth, a naturally occurring sedimentary rock, acts as a desiccant, killing fleas by causing them to dehydrate. Although all these methods have their benefits, they may not be as gentle on your pet’s skin and fur as coconut oil.

What essential oils kill or repel fleas?

Several essential oils are known to kill or repel fleas, such as eucalyptus, lavender, peppermint, lemongrass, and cedarwood oils.

However, it is essential to follow proper dilution ratios and application methods to ensure safety, and consult a veterinarian before using these combinations on your pets.

Exploring the Role of Oils in Flea Control

Do fleas have a natural aversion to certain oils such as eucalyptus, lavender, or peppermint oil?

Several essential oils can help get rid of fleas, including eucalyptus, lavender, peppermint, lemongrass, and cedarwood oils. When used correctly, these oils can effectively kill or repel fleas by utilizing their insecticidal and repellent properties.

Can oils be used for flea prevention as well as treatment?

Yes, essential oils and coconut oil can be used for both flea prevention and treatment. By applying oils with flea-repelling properties regularly to your pets and household surfaces, you can create an unwelcoming environment for fleas, helping to prevent infestations before they occur. Similarly, these oils can be used to treat existing infestations by killing or repelling fleas.
