Best Essential Oils To Kill Fleas

Introduction

There are all kinds of different parasites that can infest your pet, and fleas are among the most common. Even if you take care to keep your house clean and your pet groomed, they still may be vulnerable to an infestation. Fortunately, there are steps you can take to prevent or treat a flea problem, including essential oils. Here are a few of the best essential oils for killing fleas:

Peppermint Essential Oil

Peppermint essential oil is the perfect choice for a flea repellent, as it’s natural and safe for use on cats and dogs alike. However, it should not be used on cats because of its strong menthol content. This ingredient can cause an allergic reaction in some pets or even induce vomiting in others. If you’re worried about putting peppermint essential oil on your cat or dog’s skin, consider using another variety instead (like citronella).

Peppermint essential oil has many benefits when it comes to killing fleas—it works well as a natural flea repellent and will kill insects that come into contact with it. This makes it ideal for treating bedding, carpets and furniture where you typically see infestations occur. The same goes for any areas where your pet hangs out like kennels or crates; these are prime breeding grounds for small bugs looking for places to hide! Just add 5 drops of peppermint to 1 cup vegetable glycerin soap (or other liquid soap base), lather into suds then rinse off after 10 minutes’ contact time with clothes/blankets/etcetera

Eucalyptus Essential Oil

Eucalyptus essential oil is a powerful insect repellent. It’s natural flea control, so you can use it as a spray or rub it into your dog’s fur to prevent fleas from biting and lay eggs on them. The high concentration of eucalyptus oil in this recipe makes it one of the best essential oils to kill fleas on dogs, cats and other animals.

To make an eucalyptus flea spray:

• Fill a 4-ounce spray bottle with warm water, then add 10 drops of eucalyptus essential oil (or 15-20 drops if you’re making an all-natural bug repellent).
• Shake gently to combine ingredients; label the bottle and store in a cool place for up to 3 months.

Cedarwood Essential Oil

Cedarwood essential oil is one of the most powerful insect repellents, and it’s also an excellent choice for killing fleas. Cedarwood essential oil is toxic to fleas, but not to humans. As such, cedarwood oil can be used directly on your pet or diluted with a carrier oil before being applied directly to your pet’s fur.

Cedarwood essential oil has been shown to kill over 90 percent of adult fleas after three days of treatment (source). The primary active ingredient in cedarwood essential oil that kills fleas is sabinene hydrate (up to 72 percent), which causes paralysis in insects as a result of interference with their nervous systems (source). This paralysis causes death by asphyxiation; insects cannot breathe when they’re paralyzed like this!

Lavender Essential Oil

Lavender essential oil is a good insect repellent and flea repellent. This makes it a good option for people who want a natural way to repel insects and fleas from their pets. You can use lavender essential oil in your pet’s bedding, on their bed, or in the air around them. It’s also safe for humans so you don’t have to worry about accidentally getting some on yourself if you’re sitting down with them when they’re taking their daily bath.

If you want to know more about how much of this stuff you should put on your dog or cat, we recommend doing some research before applying lavender to an animal’s skin. Some vets say that using too much lavender can cause irritation or allergies in animals—so be careful!

Rosemary Essential Oil

Rosemary essential oil is a great choice for killing fleas, ticks, mosquitoes, lice and bed bugs. Rosemary has been used for centuries as an insect repellant. In fact, it’s one of the few essential oils that has been shown to be effective at killing all four types of insects we just mentioned—fleas, ticks, mosquitoes and lice—so you can use it to repel these pests from your home or yard.

To use rosemary as an insect repellent:

• Add 20 drops of rosemary essential oil to 2 tablespoons (30 ml) carrier oil such as coconut or almond oil.
• Apply the resulting blend to exposed skin areas so that they are well covered by the mixture (don’t apply too much). This usually means applying more than once per day until relief is felt (again depending on how many pests there are). If necessary repeat application daily until symptoms subside completely.

Lemon Essential Oils

Lemon essential oils are another effective option for killing fleas. If you have a pet that is allergic to lemon essential oils and can’t use them, try using peppermint or lavender instead. Lemon essential oils can be used on pets but not humans and they are safe to use in the diffuser with no adverse side effects.

You can kill fleas with these essential oils.

While you can safely use essential oils around your pets, they are not safe to use on cats. Cats are more sensitive than dogs to certain oils, so it’s best not to apply any on them.

Of course, you should use caution when using any kind of chemical in the home or yard. If you want to avoid harsh chemicals, natural solutions are a great choice!

Conclusion

All of these essential oils will work to repel and kill fleas. The reason that some may be better for you than others is in the side effects. For example, eucalyptus is toxic to cats but safe for dogs. Lavender, peppermint, and lemon are all safe for both pets. Keep in mind that some of these oils cannot be used on pregnant animals. Also, never use an essential oil directly onto your pet’s skin as this will cause irritation or a burn from over-concentration of the oils. You should always dilute them with a carrier oil such as coconut or olive oil before applying it directly onto your pet’s skin or fur using a cotton ball or soft cloth dipped into the mixture so that it doesn’t get into their eyes by accident!
