How Tea Tree Oil Can Easily Repel Fleas On Your Pets

Many pet owners are hesitant to purchase store-bought flea remedies for their dogs or cats as there have been many reports on these flea remedies poisoning pets. There are certain types of flea meds that are dangerous for cats but safe for dogs. The trouble for many pet owners is that cats lick themselves clean several times a day, while dogs generally aren’t as dedicated to this practice. It’s a lot harder treating a cat for fleas, as anything you apply to their fur can quickly be licked off.

There are safer flea medications you can purchase from a vet. But often fleas can also infest your yard and inside your home. You may wish to use a variety of natural treatments first, before resorting to pesticides, sprays, or prescription medicated flea remedies for your pets.

Tea tree oil is a natural essential oil. In order for it to be safe to use on pets, it’s recommended that it be diluted first, before application to pets. When you carefully follow directions, the oil can be safe for use on both dogs and cats.

Where Does Tea Tree Oil Come from?

Tea tree oil’s official Latin name is Melaleuca alternifolia, from the Myrtaceae family which is similar to the myrtle trees. This plant has a wide white coloured paper-like bark. Its green leaves are thin and oval shaped. It’s officially an essential oil, but can simply be called an oil too. This oil has a strong camphorous scent that is unappealing to fleas. But it’s much safer to apply a tea tree oil dilution to your pets, then using camphor or eucalyptus on their fur or skin.

In order to extract the essential oil from the plant, the leafy green parts of the plant are steam-distilled. The oil is collected and then treated and packaged into small amber-coloured bottles for the consumer market.

Tea tree plants are commonly grown in South Africa but can also be grown in other parts of the world too. When it’s sourced from Australia it can be called Australian tea tree oil. Besides being a flea repellant, the oil has antiseptic properties that make it useful for aromatherapy and other healthcare uses.

Is Tea Tree Oil Safe to Use on Pets?

Tea tree oil can be safely used on pets, but it MUST be diluted first. It’s not safe to use straight out of the bottle. It can also be expensive, so you never want to treat a dog or cat with drops directly out of a tea tree oil bottle.

Tea tree oil contains toxins called terpenes. These are what gives the oil its antiseptic, antifungal, and antibacterial properties. Fleas instinctively steer clear of these types of toxins, making it a good flea-repellant.

Unfortunately, there is no 100% safe way to keep fleas at bay. Every type of flea treatment for pets contains chemicals. Every type of flea treatment involves some risk. Many pet owners prefer a small risk from a natural ingredient, such as tea tree oil, than from more toxic store-bought flea medications.

Many pet owners may also prefer the small risk that tea tree oil has around children, while pet flea meds and sprays can be more harmful to smaller children or babies.

And the great thing about tea tree oil is that if your pet shows allergies or reactions to it, you can simply wash your pet and not use it again, whereas with oral flea meds, it’s a lot harder to treat an overdosed pet.

The safest amount of tea tree oil to give a pet is a small concentration, anywhere from 0.1% to 1% dilution. This small amount is safe for dogs and cats, yet it’s enough to repel fleas.

Just like a human would never swallow tea tree oil, it must never be given orally to pets.

You can also water down the tea tree oil and use it to spray on your sidewalks and pathways outside, in order to repel any fleas.

Other Ways to Control Fleas in the Home

Fleas can be pests but are rarely harmful nowadays. In the past, they have harboured the plague and other types of bacteria. They can be as common as other insects, and hard to get rid of. Follow these steps so that you can have a relatively flea-free home. The trick is to keep up with regular house cleaning and exterior maintenance, otherwise they can come back.

  • If you discover fleas on your pet, treat them with the tea tree oil outside, then leave them outside while you clean indoors.
  • The vacuum cleaner is your first defense for indoors. Use your vacuum cleaner to vacuum all carpets and upholstered furniture.
  • Vacuum your non-washable pet beds. In the future, you may wish to cover these pet beds with clean but old towels, blankets, or pillowcases, which simplifies cleaning in the future.
  • Place your pet’s blankets and washable pet beds into the washing machine. You can simply use cold water, as fleas drown in water.
  • Wash floors and flat surfaces with water and vinegar.
  • If your pets sleep on your bed, wash your linens too.
  • For outdoors, set your sprinklers to work on city-approved watering days. This will kill any fleas inside your lawns or your pathways.
  • Use your garden hose with a spray nozzle and hose down all hard surfaces around your house.
  • Consider keeping your cats indoors. They stay safer this way and are less likely to pick up fleas or get sick. You should never chain your dogs up outside. They get lonely and can get health issues. Dogs should be supervised and kept inside when you’re inside.
