Flea Bite Prevention Diet

| Modified on May 26, 2023

Perhaps the best natural solution for the irritant of flea bites is to avoid getting them in the first place. However, for pet owners this is not always easy to do. In this case, eating certain foods or taking certain supplements may make your body less desirable to fleas and keep you from getting bitten by fleas.

Some Foods to Add to the Diet

  • Garlic
  • Onions 
  • Cayenne or other spicy peppers

Some Foods to Limit in the Diet

  • Salty foods
  • Foods high in sugar
  • foods high in carbohydrates

Alkalizing Tonic

Apple cider vinegar is a popular topical treatment to prevent fleas in pets. Apple cider  vinegar can be taken internally. 1 tablespoon of raw and organic apple cider vinegar can be added to a glass of water 1-3 times a day. It is possible that as your body is more alkaline, it will be less attractive to fleas.

Hydrogen Peroxide Inhalation Therapy 

If the reason that you are attractive to fleas is because of carbon dioxide gas that your body is excreting, hydrogen peroxide inhalation therapy may be helpful to counteract this as it helps to oxygenate your body.

Supplements to Prevent Flea Bites

Brewer's Yeast

Some people find that feeding their pets brewers yeast will prevent them from being bitten by insects. This nutritional supplement is full of nutrition, including B vitamins and can be taken by people as well to prevent bites. Brewer's yeast tablets can be on the large and dry side, making it difficult to take them as often as needed to prevent bites, however.

B-1 (Thiamine)

B-1, one the vitamins in brewer's yeast, may be a nutrient that makes a body less interesting to fleas. A B-1 or B complex supplement can be taken daily and may reduce your desirability to fleas.

There are many theories about why some people are more attractive to insects than others including certain blood type, acidity of the body, presence of sweat, and excretion of carbon dioxide. The same approach will not work for every person. You may need to experiment with different methods to see how to minimized the bites you get. Let us know what you find about about diet and its affect on the frequency of bites!

Hi Earth Clinic,

Thank you for your help in many different areas. Do you have a category or have you thought of one for people who are prone to flea bites?. I would love love love to find a combination of foods to eat that would change my system enough to keep those horrible fleas from biting. Garlic by itself doesn't work.. Brewers Yeast by itself doesn't work..Not eating sweets by itself doesn't work. I battle these fleas every year from walking my dog and if anyone has found a dietary system that changes one chemistry enough to not get bit, it would be a godsend... Thank you for considering this category...

Ocean: One theory or scientific explanation of attracting external parasites is Carbon Dioxide. Evidently Fleas, Chiggers, Tics, Mites, etc have sensors that detect Carbon Dioxide exhaled from warm blooded animals and make a quick leap in that direction. For people who experience seeming higher incidence of infestations it is a sign of lowered body Oxygen content from toxicity issues. Any Detoxification or Whole Body Cleanses would be encouraged, followed by supplementing antioxidant nutrients.

Until you may embark on the former, you might try taking Neem capsules orally and applying Neem insect repellent spray on feet & legs. Oxygen Therapy like adding H2O2 drops to beverage or water will increase tissue Oxygen content.

A little electrical devise called a Zapper could be used during & after exposure times to remove the paras.

Blackstrap molasses is made from a third boiling of sugar cane after the making of refined sugar. the result being a product with less sugar and a very dense nutrient rich product that that is very healthy for you. It has a bitter taste to it making it an acquired taste. The one without Sulphur is less bitter than the one with Sulphur. But if you live in a chigger or tick area the Sulphur will come thru skin keeping you almost bite free. My grand mother lived into her late 80's and never had any gray hair we were always told it was the copper and mineral content in the well water. But looking back there was always black molasses on the table eaten at most meals. So this makes sense to all coments about helping gray hair. The next less nutrients and sweeter would be ribbon cane syrup. Just stay away from any mixture with corn syrup.
