Does Vinegar Kill Fleas? – Deter Fleas With Vinegar Spray – (Pet Safe)

The battle against pests in one’s household is a challenging task, particularly when it comes to dealing with fleas. Some homeowners, in an attempt to save money and minimize the use of chemicals, resort to household items as potential remedies. One commonly suggested solution is using vinegar to eliminate fleas. But does vinegar really work in killing fleas? Let’s explore the scientific explanation and ways to ensure the safety of your pets and a flea-free family!

Does Vinegar Kill Fleas?

The short answer is no, vinegar doesn’t kill fleas. Vinegar, particularly apple cider vinegar, is often touted as a flea killer. However, it doesn’t kill fleas in the way you might expect. The high acidity of vinegar is said to be able to deter fleas, but the vinegar doesn’t actually kill the fleas. Instead, it makes your home and your pets less inviting to these pesky critters and helps to get rid of the infestation as they leave for a more suitable environment or die out naturally.

Vinegar is not a quick fix to a flea infestation. It is more like a deterrent rather than an exterminator. Fleas dislike the taste and smell of vinegar, thus bathing your pets in diluted vinegar can help to keep the fleas at bay.

How Fast Does Vinegar Kill Fleas?

Given that vinegar acts more as a deterrent, it doesn’t really “kill” fleas rapidly. However, if fleas come into direct contact with vinegar, it can cause them discomfort and can eventually kill them, but this process isn’t instant. The fleas first have to ingest the vinegar, which can take up to a few days. Even with professional flea treatments, you’ll still probably see fleas for a bit after treatment because they can live inside your home and outside your home.

This is why vinegar is often suggested as part of a wider anti-flea strategy, rather than a standalone solution. For a more immediate effect, professional pest control treatments or over-the-counter flea products might be a more efficient route to take. For a more immediate, but still over-the-counter solution is to use bleach for fleas!

What Is Vinegar?

To understand why vinegar can work against fleas, it’s helpful to know what vinegar is. Vinegar is a liquid that consists of about 5–20% acetic acid, water, and trace amounts of other chemicals, which may include flavorings. Acetic acid is produced by the fermentation of ethanol by acetic acid bacteria.

Vinegar has been used for thousands of years for a multitude of purposes, from preserving food to treating various medical conditions. Its acidic nature can create an environment that most pests, including fleas, find unfavorable.

Is Vinegar Safe To Use For Fleas?

One of the reasons many people consider vinegar as a solution to a flea problem is because of its safety profile. Vinegar is safe to use around the house, including on most surfaces and fabrics. Plus, it’s generally safe for use on pets, although it’s essential to dilute it with water to avoid causing skin irritation.

However, you should be mindful that while vinegar can help deter fleas, it might not fully eradicate a severe infestation. Furthermore, it is crucial to remember that not all pets can tolerate vinegar, especially cats. Always consult with your vet before applying any home remedy on your pet.

How Do You Get Rid of Fleas With Vinegar? Or Apple Cider Vinegar

Getting rid of fleas with vinegar requires a comprehensive approach. Here’s a step-by-step guide to using vinegar in your fight against fleas:

  1. Create a Vinegar Solution: Mix one part vinegar and one part water. Apple cider vinegar is commonly recommended, but white vinegar will also work.
  2. Bathe Your Pet: Bathe your pet as you usually would and then rinse them with the vinegar solution. Be sure to avoid their eyes, ears, and nose. Let the solution sit on their fur for a few minutes before rinsing it off.
  3. Use Vinegar Spray: For added protection, you can create a vinegar spray by mixing equal parts of vinegar and water in a spray bottle. Lightly spritz this on your pet’s fur (avoiding the face), their bedding, and other areas where fleas might hide. Since fleas can live on furniture, it’s important to also spray furniture if you notice flea activity.
  4. Repeat Regularly: Because vinegar doesn’t kill flea eggs, it’s essential to repeat this process regularly to deter new fleas from taking up residence.
  5. Clean and Vacuum Your Home: Additionally, thoroughly clean your home, focusing on your pet’s favorite areas, and vacuum regularly to pick up any fleas or flea eggs.

Vinegar can be an effective, natural part of your anti-flea arsenal, but it may not be enough to combat large infestations. If fleas persist, it’s a good idea to contact a pest control professional for a more comprehensive solution.

Can You Mix Dawn and Vinegar To Kill Fleas

If your pet has fleas and you’re ready to take their treatment to the next level, then you should consider mixing dawn dish soap and vinegar together while giving your pet a bath!

By adding a cup or two of vinegar to your pet’s bathwater, and then adding a little bit of dawn dish soap as you scrub them you’ll notice the fleas falling off their body into the water. Although fleas can swim, the combination of the bubbles from the dish soap and vinegar will drown them in the bath.

Final Thoughts On Using Vinegar For Fleas

Fleas can be an annoying pest to deal with because they are so small but agile. Although fleas don’t have wings, they are extremely good at sneaking their way into your home. If you have pets you should always be looking for hitchhiking fleas when you return indoors with your pets.

As mentioned above, vinegar doesn’t necessarily kill fleas, but vinegar will help deter fleas from your home, and can eventually get rid of an infestation. That being said, if you have a serious flea infestation then you should look at using vinegar in combination with a traditional flea treatment.
