How Do You Make A Lavender Spray For Fleas?

[3] Ways To Make Lavender Spray

1- To make Simple Lavender spray for fleas, just mix a few drops of lavender oil with water in a spray bottle, then spritz it on the pet’s coat or another flea-infested area. This will not only keep fleas under control and leave a lovely smell, but it will also keep pets calm and energized.

2- Mix three tablespoons of cornstarch with one teaspoon of finely powdered dried lavender flowers to create a herbal flea powder spray. While brushing the pet, combine the ingredients in a spray bottle and mist the solution onto their coat. The fleas will quickly go if you do this indoors, so make sure you do it outside.

[6] Most Effective Essential Oils To Kill Fleas Besides Lavender Oil

Rosemary Oil


Rosemary has been used to repel fleas as a preventative step against flea infestations, even though there is no proof that Rosemary kills them.

To keep fleas from entering your home, soak cotton balls in rosemary oil and scatter them around. Focus on places where fleas might enter, such as around window and door frames or locations where flea activity has been particularly intense. To build an imperceptible flea barrier, place droplets of rosemary oil at window sills and door thresholds.

Peppermint Oil


The leaves of the peppermint plant are used to produce the essential oil known as peppermint oil. It has been proven that peppermint oil can potentially kill or repel fleas. Fleas can also be killed by products made with peppermint oil and other essential oils.

Peppermint oil may kill fleas in highly concentrated doses because it includes a small quantity of linalool and limonene, which are efficient flea killers.

Eucalyptus Oil


Eucalyptus oil is a pungent-smelling chemical obtained from eucalyptus tree seeds. This chemical can be applied on furniture, bedding, carpets, and other items of furniture with flea infestations to kill and repel fleas on people and animals.

Dust the carpets and furnishings with a simple flea-repellent powder you’ve made by combining 1 cup of corn flour with 10-15 drops of eucalyptus oil. After 15 minutes, vacuum up the powder. Pets will be protected from additional flea reinfection in a home free of parasites.

Tea Tree Oil

Peppermint oil

Tea tree oil can both kill and repel fleas when used properly and diluted. However, due to the difficulty of appropriately diluting tea tree oil in home kitchens, it is one of the herbal remedies classified as “terribly dangerous.”

Tea tree oil, eucalyptus oil, and one cup of witch hazel should all be added to a spray container filled with water. Spray it on your rugs, flooring, and furniture that are infested with fleas after aggressively shaking the container to combine the oils with the water.

Citronella Essential Oil


Citronella not only keeps fleas away but is well-recognized for keeping mosquitoes away. Fleas, ticks, and other insects are repelled by the natural pyrethrum chemical released by these lovely blossoms.

Mix 10-15 drops of citronella oil, ten drops of lemongrass oil, ten drops of tea oil, 5 or 6 drops of geranium oil, and 1/2 gallon of warm water to create a citronella flea spray. To get the solution to the pet’s skin and kill fleas, make sure to massage the spray into the animal’s fur.

Lemongrass Essential Oil


Fleas are very well-repelled by lemongrass oil. Fleas find the stench to be highly repulsive, while people enjoy it very much. Two drops each of Rosemary, Lavender, and lemongrass essential oils are combined with two drops of water in a spray container. Spray your dog’s coat as necessary. Make sure to avoid getting it in their eyes, ears, or face.


Fleas cannot be killed by lavender oil. Only fleas are repelled by lavender oil. Thus its use is entirely preventative. Cedar, lemon, eucalyptus, tea tree, and mint oils are among the essential oils that are known to fight fleas. Highly concentrated plant materials are used to create essential oils.

The poisonous qualities of many essential oils, especially for pets that lick them when grooming and become ill, can outweigh the benefits, such as repelling fleas, that have been recorded.
